Improved Grab (Ex): If any of its tail slap attacks hit, Drifloon may start a grapple as a free action without provoking an attack of opportunity. If both tail slaps hit, it gains a +4 bonus on the check. Spell-like Abilities (Sp): At will: darkness, hypnotism, mage armor; 1/4 rounds: shadow ball (negative energy-substituted fireball), damning darkness. Caster level equals hit dice, and the Save DCs are 10 + Spell Level + Drifloon’s Charisma modifier. The sample Drifloon has a caster level of 8 and save DC of 13 + spell level.
