In Ancestor league I made a 1hp character that was decent at mapping but not great at sanctum. I want to take this concept further by investing in niche avoidance stats. Currently, my defensive layers are:

• 45k evasion
• Chaos damage immune
• 75% spell dodge
• 52% attack block
• 75% spell block if I haven't blocked recently
• 30% chance to avoid projectiles
• 8% chance to avoid elemental damage from hits during soul gain prevention (could go up to 24 or even 39 if I lose the phys avoidance)
• 15% chance to avoid physical damage from hits

These numbers can all be tweaked, I'm not sure what stats are worth investing more into as it depends more on the damage types monsters will have (ie: are phys projectiles or ele projectiles more common? are attack projectiles or spell projectiles more common etc.) I'm also looking for other defensive layers that I might be missing.

Here's the PoB I've been messing around with, it's missing mageblood and most of the gear is just thrown together from junk I found in my standard tabs. https://pobb.in/C1lRMNT6Cpke
