Notes

Despite its fragility and limited armor access, this mutation line makes for a superb melee fighter. Fighting intelligently and managing encumbrance are vital, but the combination of speed, dodge, and stamina boosts with reduced detectability mean targets might not even realize you're there until you've stabbed them a few times. The high healing rate and moral bonuses available to the line, meanwhile, help compensate for the occasional fight where you actually get hit. Martial styles that further increase your dodge or provide armor bonuses pair well, as do styles with frequently triggered stun or knockback, and those that give bonuses for movement or waiting for an opponent to come to you.
