Sworn enemy.

Yes, but if the game drags on and I choose to play as the Elves with Winrael, and level up a Mage depending on the guild's situation, then the Rain of Arrows spell works great, plus the "Sworn Enemies" ability. For example, against Barbarians, charge with a Secret Stone and cast Rain of Arrows, and you'll block all the archers. It will be interesting to see what happens if a Cyclops casts it, as it destroys all the stones, and they deal a lot of damage with Wrath and Bloodlust. This is a very good ability, one of the best, and it will be better than Ulighi's Shadows.
