Minion InstabilityMinion, Fire Tier: 1 Level: 1Supports skills which create Minions, causing them to violently explode when reduced to Low Life.Minions from Supported Skills explode when reduced to Low Life, dealing 15% of their maximum Life as Fire Damage to surrounding EnemiesPlace into a Skill's Support Gem socket in the Skills Panel to apply its effects to that Skill. You cannot have multiple copies of the same Support Gem socketed at the same time.
The explosion is an areahit from the minion, dealing secondary damage. Its base critical strike chance is 0%.
Minions summoned from the Supported Skill must be reduced to Low Life to explode. Anything that causes a minion to die without ever having low life (e.g. dying in 1 hit, replacement, expiring duration) will not cause an explosion. Minions summoned from supported skills that are set to low life when spawned will explode instantly.
Minion Instability does not scale with the Gain X% of Damage as Y modifier. Nodes such as Seething Body do not increase the explosion damage of Minion Instability.[Likely due to a bugThis bug may already be documented in the POE2 Early Access Bug Report Forum.][citation needed]
Module Error: No results found for item using search term "item_name = Fire Exposure": Ignites inflicted by Minion Instability explosions benefit from Fire Exposure support when they're socketed in the same gem.
Module Error: No results found for item using search term "item_name = Fiery Death": Ignites inflicted by Minion Instability explosions do not benefit from Fiery Death support.[Likely due to a bugThis bug may already be documented in the POE2 Early Access Bug Report Forum.][citation needed]
Modifiers
Minions do not have the player's global stats; player stats have to be specific for minions or allies to directly affect the explosion. Stats from Auras, Sceptres, and Presence modifiers will continue to apply to nearby minions as they explode.
Because support gems affect all minions summoned from that minion skill, this support can be modified by other support gems despite itself not being a skill. The additional support gems need to be compatible with the supported minion skill, and said support gem's stats need to be compatible with the explosion's damage.

Lowering Minion Life
It's possible to make minions reach low life in the following ways:
letting them lose enough health during normal gameplay to get to under 35% life
adding Module Error: No results found for item using search term "item_name = Infernal Legion" alongside this support gem to the desired minion skill.
