When Baine throws a totem (60,000 Physical damage with knockback) be as quick as you can to throw it back at him. This will inflict 10% Physical damage, stun him for 6 sec, and increase damage taken by 100%
When a player comes in contact with the lava, that player will do 10,000 additional fire damage with melee attacks. However, this ignites Baine Bloodhoof's Mace, causing his melee attacks as well to inflict 10000 additional fire damage
When Baine uses pulverize (which does 30,000 dmg to nearby players in a 15 yard radius) the platform will be destroyed, so stay alert!
