The adventurer uses a mighty force of applied technique to create a whirlwind effect with their weapon. The result is an increase in DS against Bolts with a large increase to Parrying odds for bolts. The adventurer will suffer an AS loss. There is a small chance of hurling the bolt back at the enemy or another foe in the room with an AS equivalent or similar to what it was cast at. The mechanics may work something like this: +5 to Bolt DS per rank with 5 Ranks to Master. -1 to AS per Rank. Odds for hurling the bolt back 1% per rank. Parrying increase to bolts +10% per Rank. Much greater benefit to THW users than one hand (recommend 50% reduction for OH).
