Plasma Dragon

For effects targeting creatures by type, disintegrator dragons count as both dragons and constructs (whichever allows an ability to affect them for abilities that affect only one of those types, and whichever is worse for abilities that affect both types). They receive a +2 racial bonus to saving throws against disease, mind-affecting effects, and poison unless those effects specifically target constructs. Additionally, they’re protected from environmental effects as if wearing armor (of an item level equal to the dragon’s CR) with its environmental protection active.

A plasma dragon can shoot plasma bolts as a ranged attack. This attack has a range increment of 60 feet, targets EAC, and has the boost weapon special property (boost 1d8 + 1d8 per 5 CR), and burn critical hit effect (1d6 burn + 1d6 per 4 CR). Attacks with the plasma bolt benefit from plasma immolation (as the soldier gear boost), using the dragon’s CR as the item level of the plasma attack.
