Pyroclast Mine throws a mine that deals damage in an area when detonated, and fires multiple mortar projectiles that deal fire area damage when they land. The skill gains additional projectiles with more consecutive mines detonated. Each mine has an aura that adds fire damage to hits against affected enemies.

Skill functions and interactions

• The innate aura effect of this skill (Each Mine Adds # to # Fire Damage to Hits against Enemies near it, up to a maximum of # to #) has a base radius distance of 35 units and is scaled by modifiers to area, including those specific to auras. Increased aura effect will improve the bonus per mine near an enemy, but will not affect the maximum bonus.
  • This modifier applies globally, and can be used to add damage to hits from other skills by leaving mines undetonated.
• Pyroclast mine can hit the same enemy multiple times from a single detonation: by the initial explosion of the mine, and by every exploding projectile aoe. Both hits count as projectile damage.

Some of the double legacy enchantments have identical mod text with the last obtainable variants. It is because the enchantments were for Fire Nova Mine which converted to Pyroclast Mine. Those that have identical mod text should behave the same as the last obtainable variants in-game, except having different internal mod ids or required level. Note that Pyroclast Mine fires # additional Projectiles from Eternal labyrinth also has a legacy mod value of 2.

The duplicate converted enchantments have a separate item filter on the official trade site.

Pyroclast Mine gems dropped before version 3.8.0 retain their legacy artwork in permanent leagues.
