What is your suggestion?: Fix almost all of Vorkath's damage, this would include lowering/properly negating all 4 dragon fire hits, buffing the rapid-fire hits, and the fireball damage.
Detailed list: The yellow/green/purple dragonfire attacks should do NO damage if a super anti fire and pray mage are on when hit (that's how it is in OSRS), something on Alora isn't coded right and those 3 still smack you for 15s. The white dragonfire that summons the undead spawn should do NO damage, as it never does in OSRS, it's just an animation to summon the undead spawn. The rapid fire phase is a joke here, with the max I've been hit is a 10, and half the time it hits 0s, on OSRS with mage prayer+super anti fire it will kill you in 3-5 hits. The fireball attack here is underwhelming and needs a damage boost to match that of OSRS. The light blue ball is the magic attack and protect from magic should block it 100%.
Is this in OSRS?: Yes
Has this suggestion been accepted already?: I suggested this before on June 2nd, 2018.
How would this benefit Alora?: As of right now killing Vorkath doing EVERY mechanic correctly, you still chomp through quite a bit of food per kill, and this damage is from the dragonfire hitting incorrectly. With fixes to the dragonfire, and buffs to the rapid-fire and fireball attacks, this boss would be much better to kill, as long as you can do the mechanics properly.
