Was playing Warm Welcome on test server, and a Gnarl warrior used chop on me (5 point attack) with no bonus damage and desperate block kicked in and prevented damage.
Just happened again. This time in Quarry, with Predictable Stab and Desperate block. I'll bet Sbipple is going to stab Gorn Irontusk. Yup. Just like that. Gorn Irontusk blocked with Desperate Block. Predictable Stab was cancelled. Tough Hide failed! Sbipple took 3 Piercing damage. Gorn Irontusk discarded Desperate Block.
