Tinnin

Notes:
 * Spawned by trading a Monkey Wine to a ??? on the Wajaom Woodlands Islet.
 * Spawns at 50% HP with only 1 head, and heavy auto regen. Quickly regenerates a second head restoring 25% of its life, and then a third head restoring another 25% HP.
 * Auto-Regen seems to disappear once all three heads have been restored.
 * Susceptible to slow, elegy, and blind.
 * Immune to stun.
 * Has ability to Draw-in, which is then immediately followed by a TP move. (Including single target Serpentine Tail, single target 2000+ damage.)
 * Switches between two modes: Melee immune and magic immune.
 * Pyric Bulwark: Immune to melee attacks.
 * Polar Bulwark: Immune to magic attacks.
 * After using either Pyric or Polar Bulwark, it will immediately use Nerve Gas.
 * Nerve Gas: AoE Curse and 20hp/tick poison. As soon as mages see the use of a bulwark, they should be prepared to quickly cursna, cure, and poisona tanks.
 * Does not have TP regen.
 * Unlike the normal Hydra, black magic works very well against this, and is highly recommended.
 * Islet is accessed from (H-13) in Wajaom Woodlands after purchasing Sicklemoon Salt (key item) for 500 Zeni from Sanraku.
 * Getting the Monkey Wine from Sanraku requires a Charcoal Grey Seal, a Deep Purple Seal and a Chestnut-colored Seal.
 * Uses the 2hr move Mighty Strikes.
