Several challenges require you to find the Hall of the Penitent location in Diablo 4 and activate it for more rewards. If you’re not sure where to find it on the massive map of Sanctuary, here’s a guide with the exact location and steps to defeat Grigoire, the boss you’ll find inside.
Diablo 4 How to Beat Grigoire the Galvanic Saint (Boss Guide)
You can find the Grigoire boss in the Hall of the Penitent, which is located in Dry Steppes, near Dindai Flats and The Onyx Watchtower. You can get there from the Waypoint at the Watchtower or from the Waypoint at Kotama Grasslands.
This dungeon is available if you are at least World Tier 3 and if you are below level 60 you may have a hard time against Grigoire, the Galvanic Saint. This of course depends on your build and it is possible to beat him if you have multiple party members.
Once you've defeated the enemies before reaching the boss, you'll need Living Steel to summon Grigoire. Opening Tortured Gifts during Helltides is the best way to farm Living Steel – you only need 2 (World Tier 3) and 5 (World Tier 4) per summon.
