Thunderous Blessing on ogryn shovel lowers damage done

Issue Description:
The Thunderous blessing on shovel states that the target receives 3 Stacks of 5% Brittleness on hit, which I suppose should increase damage done by the entire team on the target hit.
However, what happens is the opposite, the target becomes more resistant to damage, lowering your damage output for each stack of brittleness.

Steps to Reproduce:

  1. Have a shovel with Thunderous blessing.
  2. Hit something multiple times in Psykhenarium.
