Increases your melee attack skills (fist fighting, axe fighting, club fighting and sword fighting) by 35% for 10 seconds. Concentrating on the fight, a knight will neglect his defense being unable to block any attack with his shield.
You can't use this and Protector spell at the same time. If both have been learnt though, Zoltan can easily switch them for a small fee of 500 gold.
This spell is useful to cast before facing a creature that would otherwise drain all your mana, such as a Priestess or Dwarf Geomancer.
