Minion. Minions always attack in groups of 3 to 5. If a minion takes damage from an attack the damage is deducted from their HP like normal. If the damage exceeds a single minions HP, then the extra damage is deducted from the next minion in the group untill all minions are at 0 HP or all the extra damage is exhausted. Extra damage points do not carry over to other groups of minions.   If the minion takes damage as a result of a failed saving throw, their hit points are reduced to 0.   If the minion takes damage from another effect, they die if the damage equals or exceeds their hit point maximum, otherwise they take no damage.   Saving throws against magic or area of affect are done at the group level. If the group saves, none of the minions in that group take damage
