The fight

Mechanics

Guthan's warspear hits count as crush, for up to 24.

His set effect has a 25% chance per hit to heal him for the damage dealt, and Protect from Melee stops that too. He's weak to magic, so tridents, Iban Blast, wind spells or Magic Dart are common. Entangle or ice spells let you fight him from a distance.

Which style: Magic. He wears melee gear, and wind spells do 50% extra.
