Tapestry: Elaborately embroidered patterns or scenes on cloth, tapestries hang from the walls of well-appointed dungeon rooms or corridors. Crafty builders take advantage of tapestries to place alcoves, concealed doors, or secret switches behind them.
Tapestries provide total concealment (50% miss chance) to characters behind them if they’re hanging from the ceiling, or concealment (20% miss chance) if they’re flush with the wall. Climbing a big tapestry isn’t particularly difficult, requiring a DC 15 Climb check (or DC 10 if a wall is within reach).
