Mestarien mestari

The Master of Masters or Grand Master (in-game name Mestarien mestari) is a boss encountered in the Throne Room, east of the Wizards' Den. Although quite slow, moving in a manner similar to the Ylialkemisti, he uses an array of dangerous attacks, which can quickly overwhelm and debuff the player to the point of death.

Behavior
The Grand Master will remain stationary in the center of the arena until he spots the player. At this point the fight begins, and the boss will slowly move towards the player, stopping from time to time in order to perform attacks.

He has 8 Orbs, 4 Death Orbs, 4 Blood Orbs, all of which slowly orbit around him. The Death Orbs make him invincible, so they have to be killed in order to deal damage. Meanwhile the Blood Orbs are not to be killed, but avoided, as the damage they receive will be unavoidably dealt back to you as Blood Link damage. This can be devastating with high damage, one shot spells. Note that this damage is nullified by Ambrosia.

When the player is visible, the boss will periodically raise his hand, and perform one of the Phase 1 or Phase 2 attacks, granted he is in said Phase. In Phase 3 the boss will only use one attack, while continuously chasing the player. Phase 2 begins when the boss reaches 50% health, Phase 3 begins when the boss reaches 25% health.

Rewards
The Grandmaster currently unlocks the following five spells, but doesn't drop the rare "2x" spell:


 * Wand Refresh
 * Add Trigger
 * Add Timer
 * Add Expiration Trigger
 * Spell Duplication - or "2x" - (not dropped)

In addition to the extremely useful Sauvan Ydin, the Wizard also drops a book titled "A Cunning Contraption". Its contents are a hint to the Crystal Key secrets.

Combat Tips

 * Don't be greedy with your shots, especially when using high damage wands. One missed shot into a Blood Orb, can take down a huge chunk of your health, or even kill you.
 * Lead the Grandmaster to a small structure in the Wizard's Den and orbit it during the fight. This can be a great solution for avoiding the Magical Burst attack, as this can mean death without shields or repulsion fields.
 * It may be wiser to use lower damage rapid fire wands, as the boss does not have invincibility frames or a shield. This also reduces the risk of losing large amounts of health due to Blood Orbs.
 * Make sure to clear the nearby area of any enemies. Kill the Wizards just as they are summoned, if ignored, they can quickly increase in numbers and become overwhelming.
 * Always check what debuff the Wizard gave you. With wands that can hurt you, do not shoot when under the Boomerang Spells debuff.
 * You can exploit the Boomerang Spells debuff to heal with a Healing Bolt.
 * You can try to hide, but be wary. The Grandmaster can't dig by itself, but his green meteor attack can. This can be used to quickly destroy his Death Orbs.
 * Melee Immunity can make Phase 3 trivial.
