Countdown ( Loop 1d4). When the Giant sees a hostile target for the first time, activate the countdown. It ticks down when a PC rolls with Fear. When it triggers, the Giant makes a standard attack against up to three targets within Close range. Targets the Giant succeeds against lose a Hope.

When a creature within Far range of the Giant critically succeeds on an action roll, the Giant clears all Stress.
