Attack Styles
Cerberus attacks with all three forms of combat:
Melee - Cerberus bites the player. This attack will only be used if the player is standing within melee range.
Ranged - Cerberus stands on her hind legs and kicks out with her front legs, firing a translucent spiky ball.
Magic - Cerberus lowers her head and fires a smooth black ball.
All of these attacks can deal up to 23 damage, and can be prayed against to nullify all damage.
Cerberus Summons 3 souls when hp is under 400
Red is melee
Blue is magic
Green is ranged
This sould deals 30 dmg if not protected with the correct prayer and drains 30 prayer points regardless you pray correctly
so its recommended to have over 60 prayer when the souls come out.
With the runelit plug it will show you the order in which you need to pray
Using a Spectral Spirit Shield will reduce the dmg to 22 and halve prayer drain from souls to 15 only.
Cerberus also spit 3 lava pools when he does de GRRRRRRRRRRRRR animation.
its easy to evade just move the opposite side and you wont take dmg.
Its recommended to pray Protect from Magic at all times
