The Evolution of Astrageldon Slime Boss (Terraria Calamity Mod)

[@GitGudWO]

I forgot to mention, this boss is a SUPERBOSS , meaning it is very hard & challenging to fight! So don't get confused if you struggle fighting it! Catalyst Mod Official Discord Server: discord.gg/Z6Pdm53mTs Calamity Loadouts Playlist: kzbin.info/www/bejne/hnjCmHWqZcp_m5Y More Notes & Details: - Phase 2 of the boss gives infinite flight, so you don't have to worry about running out of flight time. - You'll get insta-killed if you use Rod of Discord during Space Distortion. - Astrageldon won't despawn if you leave Astral Infection Biome. - I'm using an old build in the video, so this boss might be slightly easier or harder by the time you fight it.

[@borger4505]

Phase 2 honestly looks terrifying to fight, expecially for being a pre-moonlord boss

[@rio-bq2tn]

shit, no wonder why he's quite bullet hell and other stuff, i thought he's quite casual when he first release but no, he became the superboss?

@@nguyentandung42 yet its still one of the most popular mods? its not like they're making it from scratch which would be way easier to choreograph a bossfight imo, and plus they did heavy graphical reworks/creations to a few bosses eidolon wyrm (partially), SCAL, Draedon. And its not like th graphics are bad, but doing something off of something already built is difficult enough, they have to worry about balancing and bug fixes, not just bossfights, appreciate the mod a little more and you'll have better days.

[@shifan9085]

I like how this boss follows a specific patterm, hard but memorable, compared to Scalamitas which relies heavily on reaction. this one as a bullet hell enjoyer, this fits my description of a well made boss for a person who relies more on to pattern memorization Very challenging with every death being 'you' as the reason. everything just gives me the pleasure of sight just seeing it, from the sprite to how it rains bullets on you and to how it attacks you. It's a mix of of EoL and EoC and kingslime It rams you, it stomps you then it rains projectiles over you which I would say, it's pretty awesome.

[@heitorboladao2166]

I also love bullet hells, and i have to say that this boss seems to be so fun, since it clearly shows where and what It is doing, you just need to memorize the pattern, and every death is your fault, boy i wish scal was like that instead of a rng bullet hell, such a Shame

[@eliasstanciu2405]

Gotta say that the partical effects are amazing. I even like how the end of the bossfight just looks like a universe turning inside-out.

[@Sethg98]

Tried this boss out now that it's public, kicked my ass yesterday but today I managed to clear it. Really cool boss, I like that getting to phase 2 will make him automatically spawn in phase 2 (you can right click the spawner if you still want to fight phase 1 first). It makes the second phase a lot easier to grind out attempts on, as you don't have to get through the easier part just to practice it again. It's something I really appreciated about the nebuleus rework in mod of redemption and it fits nicely here with phase 2 being such a huge jump in difficulty from phase 1.

[@ZaratosBlack]

That one is much better than several Calamity's bosses. It really shines!

[@Event_Horizonn]

First we have Subspace Serpent redefining worm bosses, now it’s slime bosses’ turn with the abandoned Astrageldon Slime, coming back more powerful than ever. Very challenging but fair mechanics reminiscent of Fargo’s style, coupled with the stunning visual makes you feel like you are fighting with an actual star. Really hoping to see more creations like this in the future of terraria modding.

[@vortexofrainbows8262]
