Triggered Actions

Trigger: The yuan-ti obelisks are destroyed.

Attack (Immediate Reaction): Close burst 10 centered on the ancient shrine (creatures in burst); +14 vs. Reflex

Hit: 2d10 + 12 damage, and the target is pushed to the nearest square outside the burst, falls prone, and is dazed until the end of its next turn.

Miss: Half damage, and the target is pushed to the nearest square outside the burst and falls prone.

Effect: A 45-foot-diameter hole fills the space where the ancient shrine used to stand. Tendrils of arcane energy rise from this jagged rift.

Countermeasures

For each obelisk that was deactivated, reduce the burst radius by 1.
