  • Any melee weapon that does not require two hands (such as sledgehammers) are useful with this trait, this also counts for any Unarmed weaponry.
  • From a skill point perspective, this trait can be very strong, and the 20% bonus is a modifier rather than adding to the base chance. What this means is that higher skill levels (above 100%) the base level will remain below the 100% threshold, therefore making increases still cost 1 instead of 2 skill points, 2 instead of 3, etc. This allows for more efficient skill increases.
