Green Slime Tactics
In battle, a green slime attacks the nearest creature and uses rapid dissolution to dissolve the creature into slime.
Engulf (standard; at-will) Acid +7 vs. Reflex; 1d6 + 3 acid damage, and the target is engulfed (save ends). While engulfed, the target takes ongoing 5 acid damage and is restrained. While a target is engulfed, attacks that target the green slime deal half damage to the slime and half damage to the engulfed creature. While it has a creature engulfed, the slime can make attacks only against the engulfed creature.
Rapid Dissolution: A green slime's attacks deal 1d6 extra acid damage to a creature that is taking ongoing acid damage.
