Disintegrate. A target reduced to 0 HEALTH by an exterminator's disintegration attack is completely and permanently destroyed. No trace of the target remains.
Integrated scanner. Exterminators have scanners integrated into their audio/visual sensors. This means that they are always considered to be using a scanner.
Self-destruct. An exterminator reduced to 0 HEALTH explodes, doing 6d6 heat damage to all within 30'.
Disintegration ecstacy. When an exterminator disintegrates a living creature, it heals 2d6 HEALTH immediately.
Damage modes. An exterminator can use a free action to change its attack from disintegration to any one of heat, cryo, electricity, or ion damage. It can change to another damage type or back to disintegration with a further free action.
