Storm Sorcerer / Tempest Cleric Multiclass Build Guide: Baldur's Gate 3

One of the STRONGEST multiclasses in Baldur's Gate 3, the Storm Sorcerer and Tempest Cleric are a perfect match. There are a few different ways you can take this build, but here is my interpretation on the storm sorc tempest cleric multiclass after build testing it. I think that this It's so powerful because create water in Balder's Gate 3 is really easy to do compared to tabletop DnD 5e. Lightning damage and Thunder damage both get doubled whenever the target is wet and you can use things like mage hand to throw a water bottles or even just have your other teammates set you up to deal massive damage. This is one of the best Multiclasses in baldur's gate 3

BG3 is just unbelievable...there are so many different possibilities on whatever charachter type you want. UnFREAKINGbelievable...

[@JasonDunna]

It is incredible the amount of freedom you get! This build in particular is incredibly powerful as well

[@powerfitness135]

this is an AMAZING build guide jason thank you once again for making these great videos for us

[@JasonDunna]

Ayyy im so happy you enjoyed!!

[@8thgod769]

Character creation is on point bruh

[@JasonDunna]

Thanks bro it’s a bunch of fun modifying Tav / hirelings

[@marshallwilver8831]

Yeah having at least five levels of sorc on one of my party members is including in every single one of my teams. Twinned haste is the strongest thing you can possibly concentrate on as a support/caster in non honor mode runs. I wouldn’t worry about including it in honor mode though. It’s needed to what is in in d&d where the extra action point doesn’t benefit from extra attack. It’s still good there but it’s not the default strongest thing

[@JasonDunna]

Great points on honor mode! Twinned haste is so ridiculously broken. If you have two sorcerers with haste and water set up, it’s the highest burst damage possible. Extra powerful if one sorcerer is level 11 and twins chain lightning… so much damage!!

[@chrisxcrozz5186]

can this build also work if you focus more on the cleric side on leveling up? maybe like 8 or 9 levels into cleric and the rest on sorcerer? im doing a melee/lightning caster on my run.

[@JasonDunna]

You can definitely but the sorcerer is very strong so more levels for sorcerery points is great. Entirely up to you though!

[@VikingZeroReviews]

The gooooaaaaattt

[@JasonDunna]

I think you’d like this build because it’s basically Thor. Heavy armor, hammer, and calling down crazy lightning attacks

[@tiagozom]

if you pick chain lightning as a wizard, will you cast it using your Int ou charisma modifier?

[@JasonDunna]

Unfortunately all wizard spells will use your INT modifier but chain lightning is still good regardless

[@IVISMiLESIVI]

Wanted to play an original character so I chose shadowheart and made her a call of lightning build since that spell is great and can be repeated for free. I have gale for haste and create water and lemme tell ya casting 2 free call of lightnings every turn with shadowheart is fun and stupidly good. She's my only need for crowd control. I wasn't sure what other class to multi into so sorcerer does seem like a good choice but I'll most likely switch your wisdom and charisma stats with eachother since call of lightning is my main focus.

[@IVISMiLESIVI]

I made this comment too soon, I didn't realize storm sorcerer gets call of lightning too. Your build might actually be more optimal since you get the twinned spell and quickened spell abilities from sorcerer. Nice!

[@JasonDunna]

Yeah the sorcerer is really powerful! You can also fly after casting a spell as a bonus action which is really useful. The sorcerer is very powerful, I think it’s the strongest class in the game

[@aaronchenhall3079]

Great video, thinking about running 2 of them for my first honor mode attempt. Any thought’s on what my other two party members should be?

[@JasonDunna]

2 more storm sorcerer / tempest clerics 😂 just kidding. A druid with wild shape for tanking which also has create water is great. Moon Druids make for some of the best tanks in the game. I am also a fan of a battlemaster Fighter to fit the role of tank. Sword bard with control spells works great too! Check out my sword bard build guide for more information, it’s an extremely powerful crowd controller that can use its CC as a bonus action. It’s strong

[@ejire4407]

For me i prefer draconic bloodline because you get your charisma's modifier to any spell that deal lightning damage (if you take a lineage like blue and you are at least lvl 6 sorc) and you get (if you don't play heavy armor) +3 AC and more hitpoint. You can also get lightning resistance with a sorc point. This boost is like +5 to +7 damage without using a reaction when tempest gives you only 3 damage with reaction (so no cleric boost as it uses a reaction). The only good thing i think is the fly ability of the tempest but you get it with illithid so it's great only in early game. Tempest is also great lvl 11 with the passif but you need at least 2 lvl in tempest cleric to max damage so useless. Also a better option than Chromatic Orb of lightning (if you use the cleric boost, higher level spell slot and SINGLE target) is the simple witch bolt as you get +12 damage per spell slot compared to + 8 damage per spell slot (so it's better at lvl 3+ spell slot --> 36 vs 32, even at lvl 2 --> 24 and worse at level 1 --> 12 vs 16).

[@JasonDunna]

Yeah the draconinc bloodline blue is also quite strong. The draconic sorcerer gets fly at level 11 but if you want the cleric's channel divinity you can't get both sadly. Chromatic orb lightning is very strong! I got roasted on a video once for taking witch bolt but your application of it is very powerful. Thanks for commenting!

[@ejire4407]

@@JasonDunna Yeah witch bolt is great vs single enemy or if you want to oneshot ONE troublesome npc but if you have a zone of 2-3 npc then blast all 3 of them with double orb of lightning (but it uses 2 or 3 sorc point). I didn't take into account the "wet" statue in the calcule but it's the same thing starting from lvl 3 spell slot witch bolt deals an amazing 72 damage on wet with cleric boost at lvl 5 so basically nearly the entire health bar of ANY npc at that time and can 2-3 shot boss fight. If you have the draconic bloodline it's 82-90 damage and with other boost you can get nearly 100 damage with 1 spell at lvl 3-4 spell slot. BALANCED ! So depending on how the enemy are position on the map you deal more damage than orb of lightning.

[@keatongraffis6232]

All spells cast through items will scale of WIS if you take Cleric LVL 1 after Sorc LVL 1.

[@JasonDunna]

Yes that’s true

[@section4344]

The best piece of gear for this is easily the Markoheshkir. Using Kereskas Favor for lightning, you get a free use of Chain Lightning and a level 6 Lightning Bolt on a short rest, get your proficiency bonus added to lightning spells, and Arcane Battery gives you just a free spell each day, which can come in handy if you took a Wizard dip and learned Conjure Elemental to get a free Myrmidon. Also, something of note, the Chain Lightning from Markoheshkir can still be twinned when it can't be from scrolls or knowing it anymore, letting you delete entire groups of enemies and even some tankier targets.

[@JasonDunna]

Great point! The Markoheshkir is really strong, being able to twin chain lightning is straight up broken haahha. So much damage alongside create water Thanks for the comment!

[@blazesmith3678]

What did you do for background?

[@JasonDunna]

Noble, Sage or acolyte make the most sense for a sorcerer cleric but pick the one that feels best for role playing

[@sasori2749]

is this better or pure storm sorcerer? i don’t really care for heavy armor

[@JasonDunna]

Tempest cleric gives the lighting attack reaction, and their channel divinity can allow you to deal maximum lightning damage which is really strong!

[@Quantum_Bluntz]

Oh yes. It’s time lol

[@JasonDunna]

This build is straight up broken, having guaranteed 224 lightning damage w/chromatic orb on critical hits in water is insane 😂 I am loving my durge sorcerer it’s strong at 12 sorcerer but adding tempest cleric for heavy armor and guaranteed max lightning damage is wild.

[@Quantum_Bluntz]

@@JasonDunna ahhhhh man right now I’m tempted to turn this into my Shadowheart (Who I completely randomized what she’d do with Nightsong by saying nothing. I had the mission to kill Isobel that I think would’ve happened if that triggered I guess). Currently running her as a Land Druid with mainly Swamp Spells to focus on adding Difficult Terrain and nuking people in it unable to move. All my characters have immunity to difficult terrain. Then I had to add a bit of survivability because some of the difficult terrain does damage to you even if you’re an ally so yeah. It’s a work in progress. Just haven’t really seen anyone make builds themed around applying conditions to the terrain like that and the one I made in particular is themed around a very strong Concentration spell that can only be seen through with a specific ring (that I don’t happen to have so there’s that. I’ll just mention it in the video). Working on fine tuning the Thumbnail then imma go back through my script and make sure I can record everything right lol

[@JasonDunna]

@@Quantum_Bluntz I think this is the highest damage a cleric can do honestly! Shadowheart as a Druid is funny but the strategy you’re using is great. Difficult terrain is unreal for crowd control which the Land Druid is a master of. I let Shadowheart do what she wanted with Isobel and on my Durge playthrough she let her live which was not what I was expecting, I think it depends on your characters approval rating with her, if it’s high I think she spares her but I’m not sure. Looking forward to the video!

[@re_syz]

Why can you cast chain lightning?

[@re_syz]

Nvm, just saw that wizard 1

[@JasonDunna]

Markoheshkir legendary staff can also give it with the Kereska's Blessing lighting option!

[@Keyroye]

I still dont get the lv1 wizard into the class

[@JasonDunna]

@@Keyroye since you have full spellcasting levels you can take any wizard spell, so you can grab conjure elemental to set up water for your lightning/cold spells Other utility like minor elemental for dual ice mephit, globe of invulnerability, and whatever scrolls you find. You can use intellligence circlet to prepare 4 wizard spells with 1 level You also don’t have to take the wizard level if you want another sorcerery point! There’s like 5 optimal ways to run this build it’s that OP

[@Emolilyx]

Could you do 11 sorrocer 1 cleric?

[@JasonDunna]

Yes! You won’t get the channel divinity from cleric but you’ll get chain lightning from sorcerer

[@Emolilyx]

@@JasonDunna decided to do 2 cleric for the destructive

[@JasonDunna]

@@Emolilyx it’s quite strong!! I usually play with 2 storm sorcerer / cleric multiclass because twin haste + create water = everything eliminated on the first turn of combat

[@Emolilyx]

@@JasonDunna what's a better multiclass storm sorcerer cleric or 10 sorcerer warlock 2

[@JasonDunna]

@@Emolilyx personally I think cleric for heavy armor and the channel divinity. Also being a cleric gives you lots of unique dialogue options

[@thegrandmasterrevan9424]

Does this still work?

[@JasonDunna]

Yes it does!

[@dyinggiraffe2922]

did you just say you get firebolt from half wood elf lol

[@JasonDunna]

Oh man I derped on that 😂 My dark urge is a high half-elf with firebolt and I forgot I was playing on my other durge playthrough where I remade the character from a hireling. Wood elf has 1.5m increase to movement speed

[@bobkatfan2013]

If you go sorcerer first, your items will use wisdom modifiers instead of charisma. Might be best to go cleric first.

[@JasonDunna]

Whatever skills you take for each class will scale off the respective class’s spell-casting ability score

[@bignickm27]

@@JasonDunna They're talking about the bug that causes any spells you cast that are granted by items (i.e. casting Scorching Ray from the Circlet of Blasting) to use the primary spell-casting ability of the most recent *new* class you multi-classed into. So in the case of a this build that levels as Sorc>Cleric, any spell you cast that is granted by an item you're equipping will use Wisdom as the spell-casting ability in its calculations (because the Cleric's spell-casting ability is WIS, and Cleric is the most recent *new* class you leveled up as). Then if you take a level in Wizard for level 12, all spells you cast that you get from items will be using INT in their calculations. So the way to avoid this bug *should* be to make sure that you don't take any levels in a new class after taking your first Sorc level. This way, if you cast any spells from items or scrolls, they'll use CHA, which is what you'd want for this build. :) www.reddit.com/r/BG3Builds/comments/185s5kl/determining_what_ability_modifier_casting_stat_is/

[@besgarknightshade3241]

@@bignickm27 My plan is to take 1 level of sorcerer to get Con and Cha proficiency, 4 levels of storm cleric with a feat, and then 7 levels of Sorcerer... which will end up with Alert feat, 16 Con, and 20 Cha (which are starting at 15 and 17 respectively). And since I am ending with sor (and not taking wiz) I should be good with items?

[@bignickm27]

@@besgarknightshade3241 sadly no, the only thing that matters is the most recent “new” class you take a level in. And since you started as sorc, even if you go back to sorc later it isn’t the most recent “new” class. Your most recent new class would be cleric. So scrolls would use your wisdom modifier
