Stone Statues After losing 20 HP, Achates will teleport to the center of the arena and become invincible.

Curse Achates will place a blue and red curse on two players The players must move together for a short time to break the curse. If the curse isn’t broken, the player with the red curse will take damage over time until they die
Earthquake The Guardian slams on the ground once and summons cross shaped rifts below and around him. After a slight delay, he will slam once more and cause the rifts to explode Avoid standing in the cracks
Wing Attack Achates lifts up and flaps his wings to deal damage and knock up everyone below him Move as far away from the attack radius as possible as soon as he flaps his wings
Flying Charge Achates charges at a player. If he disappears, he will attack the same player again The first can be dodged, but the second is harder to avoid. Wait two seconds from his disappearance and then dodge perpendicular to the original flight path
Light Explosions Two or three light explosions will happen around Achates Stay away from Achates, and if the light explosions target the player dodge out of them
Breath Achates breathes on a target, leaving them with the Scorch debuff Dodge to the right, left, or towards Achates. If he breathes backwards, go in the opposite direction.
Light Field Fires multiple different conical hail AOEs in a circle around its body. Dodge out of the cones as soon as they appear.
Scorch Mark Two players are caught in an enclosing ring which creates a firey field below whichever it touches first You cannot avoid this, so take the ring to the edge of the battlefield away from others, then dodge out as hits
