Burrower Larva

The Burrower Larva is a difficulty 2 Underschool Boss occurring in the Lava Mines which can be re-battled.
== Location ==
The Burrower Larva is found in the Lava Mines level of the Underschool.
== Combat ==
Unconventionally, the Burrower Larva is fought in a special arena specific to the Lava Mines. During combat, only the Burrower Larva is present on the enemy team, making the fight less dangerous than similar Difficulty multiple enemy encounters due to a smaller Action Economy and reducing the effectiveness of Area of Effect spells such as Miasma. 
The Burrower Larva is Level 2 Difficulty battle which can be rematched after completion by using the Burrower Larva Rematch Effigy found in the Underschool Chamber it is originally fought within. 
The chamber housing the Burrower Larva can only initially be reached through a series of 3 battles that must be completed one after another, as after beginning the first battle those involved in the combat will be locked into the chamber until the Burrower Larva is defeated or all characters have died. During this time, staff or students will be unable to seek Medical Rest or Refill Mana outside the use of Potions brought into the initial combat. It is recommended that players bring several Potion of Rejuvenation, Potion of Recharging, and Revival Flask if available, and to fully rest and feed battle participants before entering the starting battle.
=== Phases ===
The Burrower Larva has two different combat states.
===== Attacking =====
Generally, the Burrower Larva begins combat in an attack state and returns to this state after completing a Burrow.
===== Burrowing =====
Every few turns, the Burrower Larva will submerge itself in Lava for a turn, becoming un-targetable for the duration and triggering movement effects such as Thorns. This action occurs even if the Burrower Larva has been been slowed. After emerging from the Lava, the Burrower Larva will fire an Area of Effect fire attack damaging all friendly staff and students not protected by Shield. Low health characters can be killed by this attack, as it generally deals 40 damage, and potions should be used when Larva is un-targetable to prevent Death Save.
== Trials & Medallions ==
It is common to summon students who have trails such as Detachment which require them to defeat the Burrower Larva solo. 
Due to the ability to rematch the Burrower Larva at any time after completion, the fight is also useful for completion of Trials involving winning battles or landing killing blows once sufficient Wand Level has been achieved.
