On page 290 of the adventure Waterdeep: Dungeon of the Mad Mage (area 1 of Level 23), there exists a statue with the following description:
Anytime a creature other than Halaster tries to cast a spell in this room, the statue's arms animate and perform the quick series of somatic gestures needed to cast counterspell. After casting its spell, the statue reverts to its inanimate state until triggered again. The counterspell attempt succeeds automatically. The statue is a Large object with AC 17, 50 hit points, and immunity to all damage except force damage.
Given the following facts:
- Only force damage can damage the statue, so any weapon attacks are useless
- No spells can be cast to damage the statue (spells are instantly counterspelled at 100% rate of success, and the statue is not limited to one reaction per round)
Is it impossible to destroy the statue? Or is there any way that I missed?
