POE Forged Maw Beast Spectre
These use a Basic melee attack with average damage.
They have a vomit spell on a 6.5 seconds cooldown which triggers 2 spells;
A vomit mortar that deals physical damage with 25% of physical damage converted to fire, it also has 30% less damage, and does not seem to benefit from additional projectiles.
And it triggers a knockback wave spell that deals low physical damage which knocks enemies back with 600% increased knockback distance.
These have 35% to all elemental resistance and 20% to chaos resistance.
They have about 60% the life of the Primal Crushclaw.
Overall,
cool looking spectre, the large knockback distance might be interesting for a niche mechanic.
Don't think they are good enough for an actual dps spectre however.
These can be obtained from Verisium Ore nodes in the 3.25 league mechanic.
