Sapper Shovel Special attack counts as 2 hits for serrated blade, but only 1 for Onslaught

Issue Type (Required):

Weapons

Issue Description (Required):

Each heavy special attack on the mark III and VII sapper shovel hits enemies twice.

For “serrated blade” on the veteran talent tree, a single heavy special applies 2 bleed stacks per hit, for a total of 4 bleed stacks.

The Onslaught Talent on veteran’s talent tree does not apply any stacks of brittleness on first hit, but should apply 1 stack of brittleness on the second hit. If you repeat the same attack (hitting twice) it only applies 1 additional stack of brittleness, but should be +2 stacks. This results in each special heavy attack stacking brittleness 0,1,2,3,4 instead of 1,3,5,7,9.

The Limbsplitter blessing also seems to treat it as two separate attacks, only applying the 60% strength buff to the first hit. Trauma also treats it as two separate attacks.
