Glavoid

Notes:

 * Spawned with items/keyitems: Fat-lined Cockatrice Skin, Sodden Sandworm Husk, Luxuriant Manticore Mane, and Sticky Gnat Wing at (I-5) in Abyssea - Tahrongi.
 * It's stunnable.
 * It casts slowga, stonga IV, quake 2
 * Absorbs physical damage while readying and shortly after TP moves
 * Absorbs magical damage while and shortly after casting spells
 * Absorbed amounts are double the normally inflicted damage
 * Hate gained via absorbed count as the absorbed amount (eg: Healing him for 1500 will net you the hate of a 1500 nuke/ws)
 * Uses Blood Weapon multiple times.
 * Gains stoneskin effect after every TP move / Blood Weapon.
 * The amount of damage stoneskin can absorb depends on how much you healed it in the last period. For example if you hit it once by mistake (healed it 50), it gains a stoneskin of 500~. a 1000 damage Tachi: Gekko can result in a powerful stoneskin (required up to 4 Tachi: Gekko to dispel it).
 * The ability Gorge can also count towards next stoneskin. Same with Blood Weapon.
