Altar of Pain
Level 7 Blaster
XP 300

This crude altar is carved from black rock, the dark bloodstains of uncounted sacrifices covering its surface and the ground around it.

Hazard: The altar occupies 2 contiguous squares, and it is imbued with abyssal power deadly to creatures that oppose its purpose.Perception     No Perception check is necessary to notice the altar.Religion     DC 14: This area is oppressive with the presence of this black altar, which is dedicated to the power of the Abyss.     DC 19: The altar deals damage to enemies that fight within reach of its power.TriggerThe altar activates when a nondemon adjacent to it or on it takes damage.AttackImmediate Reaction      Close burst 3
Target: Each enemy in burstAttack: +10 vs. FortitudeHit: 2d6 + 5 damage.Special: The hazard treats all nondemons that are not part of the altar’s demon cult as enemies. It treats all members of the cult and their allies as its allies. The altar blocks movement, but a creature can jump onto it by making a DC 10 Athletics check.Countermeasures     Religion DC 19: A character adjacent to the altar can attempt to sanctify it by making a Religion check (as a standard action). If the check succeeds, the altar makes an attack (as above) that targets its allies rather than its enemies. The altar cannot make another attack until after the end of the character’s turn. With three successful Religion checks, the altar is destroyed.
     A character can attack the altar (AC 5, Reflex 5, Fortitude 10, 40 hit points). Destroying the altar ends its threat.
