Captain Greenskin

Ironclad Cove
Follow the docks to Mr. Smite at the boarding ramp before climbing the ship. Cookie is an optional lower-deck detour. Continue upward through Captain Greenskin, clearing his group before approaching Edwin VanCleef above. After VanCleef, leave through the passage behind the ship and meet Alba outside if you planted the forge explosives.
Captain Greenskin
Captain Greenskin's Cleave and Poisoned Harpoon punish a crowded tank position on the climb toward VanCleef.
Abilities

Cleave
Cleave also hits the tank's nearest ally; keep other players apart from the tank's position.

Poisoned Harpoon
Inflicts normal damage plus 30 to an enemy, then an additional 45 Nature damage every 10 sec. for 1 minute.
Remove the poison if your group can; otherwise heal its continuing Nature damage.
Tank- Bring Greenskin's group back onto cleared deck rather than fighting at VanCleef's approach. Keep other players away from your position so Cleave cannot catch a nearby ally.
Healer- Remove Poisoned Harpoon if you can dispel poison; otherwise keep healing its periodic damage. Stay apart from the tank to avoid becoming Cleave's second target.
Damage- Finish Greenskin's escorts before the captain, fighting apart from the tank's position. Clear this group completely before climbing toward VanCleef.
