[@eddieb1346]

Another nice way to rely to purity is using the harvester scythe and infinite Ocular HDU, that combo is similar to a Masive leech efect but with aditional crit. At least in mercenary works very good.

[@arthurtyo3140]

Woolie, try stacking capped crit on Mercenary, prioritise attack speed (choose mostly Predatory Insticts) and after capping the crit try stacking Soldier's syringe (play with command artifact as well, then stack 5 purities and u can spam R nonstop

[@fernando_kba]

i like to stack puritys and double-bands using bandit with Desperado. Gets insane on the late game

[@quintessenceoflife7870]

I like the definition a friend gave me. Basically thing of it as a roll of a dice. if you get a 1 whatever you're proccing happens. if its any other number nothing happens. +1 luck means if it rolls on any number that isn't one you get to roll the dice again. And vice versa for negative luck and negative effects.

[@skyp.a.5777]

The basic idea with Purity is to take it on Survivors who A. Have abilities in their kit that can reach that .5 second minimum cooldown after a SINGLE stack of Purity or B. Can somewhat ignore the downside of -1 luck by merit of not being very good with Proc chains to begin with. It's also worth noting that on a regular Monsoon or Eclipse run, how much purity effects you is based SOLELY on the items you currently have and which items you would expect to get going forward. It's a good decision point lunar, since it gives you a VERY potent immediate effect (if you aren't already loaded up with Ukelele's and ATGs) at the cost of changing which greens you can print / take from tri-terminals in the future. Put another way, if you do take Purity you then need to move as fast as possible through each and every stage since you won't be able to guarantee a higher total dps from those eventual ATG and Uke drops, lowering the overall item value per stage. And one last note, while it's pretty obvious given the two above conditions that you absolutely should take Purity on specifically Loader, Artificer and Acrid, I'd actually say that there are other survivors who you CAN take it on somewhat consistently, albeit at a much higher trade off: -Huntress (when using Strafe and NOT Flurry) can take Purity to both reduce the time between Glaive + Backup Mag stacks and set Phase Blink to the .5 second minimum, DRASTICALLY increasing your movement speed and map traversal if taken early enough. -BOTH of Mercenaries Secondaries reach the .5 second minimum after a single purity, making combo's much easier to maintain and stack while also letting you cheese either infinite jumps or infinite air time. Less time between both Eviscerates AND Slicing Winds also helps A LOT early on. -Engineer can sometimes take it so long as you've opted to go with Harpoons instead of the bubble. It also doesn't hurt Visions too too bad either, provided you can mitigate the luck loss with either extra item stacks or you know, just... Yolo into a Clover :P

[@Buglin_Burger7878]

For most of your damage/group killing having a few Wisps and sacrificing your AtG and Uku will instantly kill everything. It is one of those things that in the situation AtG is useful a Wisp and Voodoo Doll does the AtG infinitely better. The DPS isn't an issue if you have bleeds which max out quickly and attack speed as well. Basically the AtG/Uku benefits quickly fall off versus stacking other items which provide a constant and bigger effect.

[@skyp.a.5777]

@@Buglin_Burger7878 Not Really. Exact opposite infact. Woolie Mentions it in this video, but the big selling point is that AtG and Uke can actually proc OTHER on hit item effects cause each of their "attacks" also have their own proc coefficient. That's what a "Proc Chain" is: one item triggering on hit triggering the rest of your on hit which trigger the rest of your on hits ad infinitum. Not only that, but Will o' Wisp only works off of BASE DAMAGE, while Uke and AtG both use TOTAL damage (or the damage done by the hit that triggered them, modifiers items and crits INCLUDED), meaning you'd need to continually keep stacking wisp to get close to the total damage output that just one or two Uke's and AtG's can provide late game. Will o' Wisps are great for rushing early, but their effectiveness vastly drops off on Monsoon and Eclipse around stage 3 or 4 on everything but Command runs, and on Command almost anything is viable if you stack enough of it. Check out Woolie's item tier list for more details on this as it's pretty thorough with how each green compares.

[@Saint_Wolf_]

Man, my first go at Mithrix, blind, huntress monsoon with tonic and clover saved me, I read comments of people who had anywhere from 10 to 20+ afflictions upon going off the effect of tonic and me thanks to clover had three when my items were taken from me.

[@travis3403]

I've been having a fun time testing purity builds more specifically with the engi with mobile turrets and uhh visions of heresy? (the thing that changes your primary attack) i thiiink it lowers the cooldown on it

[@mowermen1762]

It does also get 8 soldiers syringe the turrets will shoot faster

[@mowermen1762]

In my opinion if you get the mobility and a few bustling fungus engi is the best

[@samuteel]

So it’s like D&D’s advantage and disadvantage mechanic

[@pokechu5k]

I like purity on merc because it's a nice and simple way to get complete invincibility if you spam eviscerate, and then I can grab as much glass as I want because I wont take any damage anyways.

[@mcx8095]

With a single purity on heavy mode launcher MULT-T, you can essentially fire rockets forever regardless of attack speed.

[@eac-ox2ly]

Damn, now I wanna try a Purity stacking run.

[@DKKiller581]

So one way I like to think of the luck stat is to think of it like advantage from DND, You roll dice equal to your luck stat if it's a positive number, then you will have advantage, if it's a negative number, it's disadvantage. It makes explaining it a lot easier and it's nice

[@ancientpiguardian7462]

yes

[@raynegallaher7661]

The way I see it it's like advantage and disadvantage in dungeons and dragons. Exactly like that in fact. So if you've played DND you now completely understand luck

I'll be honest I think Purity is legitimately the most interesting lunar item in the game. It has a very strong positive effect, and a very strong negative effect, it just feels like it follows the design philosophy of lunar items far better then the rest of them.

[@CreationsFlare]

Purity turns Acrid's ranged right click down to 0.5 territory. Since he can also sprint and spit while running, he can become a pseudo Huntress with just it alone, which is funny.

[@swapertxking]

I have seen someone stack 3 purity’s onto acrid and I have seen that same acrid have no chains of their own R.

[@thepengolem7850]

Hey Mr. Streamer, serious question. How good would you say Purity is on Artificer? Artificer already doesn’t scale all to well with traditional itemization, and the flat cool down reduction would be great for improving her basic attack timing. That’s just my theory craft on the matter though - I have yet to get a Purity on the jet pack gal to test it myself

[@itol2201]

I know I'm hella late, but I just tested this today after finally unlocking Purity. Two Purity gives her essentially seven shots of M1, with another one every half second. 3 negates the cooldown of her M2, and gives her other abilities respectable recovery.

[@mcawesome9705]

I'll just mention that the lower the proc chance of something is, the higher the effect of purity and clover. But while for clover it is linear (at 1 stack, slightly exponential for more), for purity, it's exponential. With a clover, you are 1.95, 1.9, 1.85, 1.8, 1.75, 1.5, and 1.25 times as likely to get a proc at 5%, 10%, 15%, 20%, 25%, 50%, and 75% proc chance. With a purity, you are 20, 10, 6⅔, 5, 4, 2, and 1⅓ times less likely to get a proc at 5%, 10%, 15%, 20%, 25%, 50%, and 75% proc chance. Exact formula for clover: (1 - (1 - x)^(y + 1)) / x, where x = proc chance, y = clovers (note: with 1 clover, this is simply 2 - x) For purity: 1 / x^y, where x = proc chance, y = purities

[@Z4ifir]

Use your numbers to be more time efficient. Game scales faster with more players so you have to scale faster as well. For example if there are still chests and you finished the tp one of you grabs it while the other waits to hit the tp as soon as the other looted to save the time it takes to get back. Coordinate which part of the map you explore but stay together if damage is lacking. You can start the boss before your teammates are there, but ask before so they can loot nearby chests before heading your way. Don't stress to much about who should get which item, running across the whole map with a slow surviver is usually not worth it unless the item is really potent for that character. For example an alien head with an artificer in your team or something like that.
