The build is in poe forum at the witch thread, Detonate dead of chain reaction CI. It is super super tanky, but lacks damage and it feels clanky sometimes. You cant scale the damage even if you have lot of currency, it has a ceiling in damage. Unless new mechanics are introduced.
sanctuary is the T17 map that has Caterina as a boss and the Abyss bossess too? If yes I did a sanctuary, it had %life as extra energy shield, and enemies get endurance charges whehn hit, monsters have +1 maximum endurance charges... it took forever. Took me like 5 minutes or more to kill all those bosses. But still never died, the energy shield never dropped from full. The build is immortal, but it has very low DPS, even with super investment, you wont have good DPS. Even if you have 10 mirrors, you cant add more damage.
@@adamkaszonyi3660 I did that map , it has the Lycia or something as a boss. It did not go well, map had 45% increased damage, 150 physical as extra lightning, and I clicked a pillar that gave boss 98% phys as extra cold. So I was two shoted when I entered arena. I have to try with different mods.
