Battle cry (Whenever this creature attacks, each other attacking creature gets +1/+0 until end of turn.)
Heroic — Whenever you cast a spell that targets Rosnakht, create a 0/1 red Kobold creature token named Kobolds of Kher Keep.
Rosnakht, Heir of Rohgahh's last ability goes on the stack above the spell that caused it to trigger and resolves first. It resolves even if that spell is countered or otherwise left the stack.
