"""Explicit, offline damage sanity check; reads no live game state or RNG.

Supply every relevant field/type/item/ability multiplier yourself. This uses
the ordinary damage formula as a planning estimate, not a battle simulator.
It reports the complete multi-hit move to prevent per-hit undercounting.
