Ruins

The Ruins are the first dungeon that can be explored. The former halls and seat of the Ancestor's power, the Ruins are now a black, shifting maze of corridors firmly under the control of the Necromancers and their continuously expanding undead army.

Provisions
Antivenom less effective here than in other locations due to comparative lack of DOT attacks. Holy Water extremely useful for curio interactions, with Skeleton Key being a close second considering the amount of locks usually encountered.

Party Composition
Characters reliant on doing Bleed damage much less effective in Ruins than in other locations due to the presence of skeletons (which cannot bleed). Conversely, characters proficient with Blight attacks become extremely useful here as most enemies have very low blight resistance, and there are a few enemies with high PROT (less susceptible to regular damage, more susceptible to DOT).

Crusader does realy good in Ruins due to his increased damage to unholy, Grave Robber is fast enough to kill Bone Courtiers before they get a turn.

It's also worth noting that the Ruin's traps only do regular and stress damage, with no DOT or debuff.
