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.


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.

Phase Attack Description
Phase 1 & 2 Random Debuff A purple, slowly closing in circle will appear around the player. After about 2 seconds, a random negative status effect will be applied. The effects can be, but are not limited to:
  • Drunk
  • Twitchy
  • Heartache
  • Boomerang Spells
  • Neutralized
Green Meteor A fast, green meteor, that deals 125 explosion damage.
Summoning Spark A sparkly, yellow projectile, that doesn't deal damage, but upon expiring will summon a random Mestari enemy.
Magical Burst An inaccurate burst of multiple blinding, polymorphing, teleporting and neutralizing magical projectiles.
Phasing Sphere A blue sphere, that travels in a phasing manner. After some time of flight, it will fire 3 copies of itself, which behave similarly. This process can quickly get overwhelming, but stops after enough copies have been created.
Phase 2 Blood Tentacle A long, red tentacle that deals 25 melee damage on contact.
Phase 3 Tentacle Frenzy This attack is constantly used for the whole duration of Phase 3. The boss will fire Blood Tentacles in random directions, and gains a speed boost. In addition to that, any nearby enemies will start using Blood Tentacles, until the Grand Master is killed.


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

Note: These spells might also be unlocked if the Ylialkemisti drops Wand Refresh and you cast that.

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.

"The secret lies in music!
The key to the heavens' lock is borne from music all over the world.
And in a way, as above, so below..."

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.
  • In the first two phases, you can abuse the fact that the Grandmaster will raise its hand to head level when casting its attacks. If you manage to get the Grandmaster to the opposite side of a wall that you are facing and then open a gap in said wall near its lower body, you will be able to freely attack it without any of its projectiles hitting you, as the Grandmaster will generally sit still and cast projectiles that hit the wall instead.
  • 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 heal by shooting Blood Orbs with 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.
  • Stain with Ambrosia is recommended.
  • It loses invincibility for 1 frame every 100 frames in phase 1 that it is possible to kill it with Piercing Shot and Homing.

  1. Although this spell is in the drop/unlock pool for this boss, it currently is never dropped directly from the boss due to a bug.
