Best if paired with abilities like Frenzy or Zeal, for extra fast killing. Find any 2-socketed weapon with Very Fast Attack Speed and you’re good to go. This effect has a chance to shave off a percentage of the enemy’s life (the health reduced varies by the type of monster in question, with champions, uniques and bosses taking less damage than normal enemies), meaning the faster the weapon, the more damage it’ll do regardless of what the damage numbers otherwise indicate. While it does require an Amn rune and yields little in the way or +% Enhanced Damage, Strength does provide one incredibly useful modifier: Crushing Blow. Bonus points if you shop around until you find a normal (non-magical) staff that adds +3 Fireball, in which case Leaf will last you until you get a Spirit sword. The +3 to Fire Skills is just killer, and best of all, works with classes like the Fire Auradin and the, too.
Perhaps the most compelling reason to play a Fire Sorceress at the beginning of the game (even if you ultimately want to respec into something else), Leaf is cheap to make with runes easily farmed from Normal.
