Destructive link not working while unarmed

Tested with a friend in hideout.

When attempting to use destructive link while unarmed (with rigwalds curse equipped for the +7% base crit), linked target's crit chance does not get updated to match the main hand crit chance stat in my character sheet (using default attack to check).

It is possible that the skill only counts the crit chance from an equipped weapon item, but in that case the tooltip is misleading and should probably be updated.
