Add in Target dummies that represent different monster types (Beast, Gremlin, Construct, etc.) to test weapon damage against. Add a small obstacle course/puzzle room for Guild Races or testing a loadout. Add the ability to spawn training monsters that do 0 damage, and drop no items/crowns and give no heat.

Or something similar.

Has this already been suggested? I apologize if it has. I'm just not sure what to search for, and nothing I searched for yielded any real results.
