Pistol skill #1 “Explosive Shot” doesn’t trigger aoe bleed on explosion as indicated on the tooltip.
Instead, explosion damages multiple adjacent targets, but only triggers bleeding on one.
That may be related to a bug combining this skill with the flamethrower tool belt skill “Incendiary Ammo: Burn foe with your next 3 attacks”.
Attacking 3 times a target, with the buff on and Explosive Shot, will only trigger the burning effect once, even on a single isolated target. Also, the buff will be removed after only 2 attacks.
It seems the game considers Explosive Shot to be 2 attacks at once?
