PoE2 Gearless & Gemless* - Arbiter of Ash (*support gems allowed)

Defeating Arbiter of Ash without any gear or skill/spirit gems.

I wasn't happy with how easy my previous gearless fight turned out to be so I upped the ante and I'm quite happy with the result. Not very happy with my performance in the successful attempt (especially that sprint fail - I thought it's a foolproof strategy, but I found out it isn't). I was supposed to change the "Heft" support gem to "Execute II" at the last 35% of HP, but I just didn't find a good time to do it.

One thing to add is that I could've taken the "Punctured Lung" node to stop the Arbiter from healing in the transition to the second phase (at least I think so? Even though it's the minions that break the armour?), but I consider that to be an exploit as it clearly is not an intended interaction.

Self-imposed rules:

• no weapons, armour, jewellery, flasks
• no jewels
• no skill or spirit gems
• no lineage support gems

About the bug shown at the end: I'm getting killed by the small projectiles from the "bullet hell" shooting balls in the first phase. My theory on what is happening is that once the big balls that shoot projectiles get far enough away from the player/arena they get flagged as "not to be rendered" so it doesn't even do the typical check if entity is in view or not to check if it should be rendered or not which includes the small projectiles that shoot back to the arena. I tried a strategy where I intentionally make Arbiter shoot it to the middle of the arena and follow the balls and I belive it helped, but ofc it made dodging the projectiles much harder. I don't have big enough sample size to say for sure it worked, but I decided to just do the strategy of using the water bubble to help tank a single hit + just gamble that it won't happen.
