Zenyte Teletab or Max cape
1-2 Super combat potions
6-9 Prayer potions or Super restores
Sharks or better food for remaining inventory space
Mechanics:
Use Protect from magic as a default prayer, as Cerberus uses Magic as his main combat style.
Every 40 seconds Cerberus will attack with a Magic Ranged Melee attack no matter how far you are from her. This mechanic has a cooldown of 40 seconds
When below 400 health Cerberus will occassionally howl Aaarrrooooooo, spawning 3 ghosts. You must pray accordingly to each ghost. Spawn order is random, but they attack from East to West (e.g. Green -> Blue -> Red). If the right protection prayer is used, 30 prayer points are drained in the absence of 30 damage. If you use a Spectral spirit shield, 15 prayer points will be used instead.
Blue is Magic
Red is Melee
Green is Ranged
When below 200 health Cerberus will occassionally howl Grrrrrrrrrrrrrr, throwing out three exploding markers onto the ground: one under the player and two nearby. 10-15 damage is dealt from the marker if the player is on top of it. Seven damage is dealt if the player is next to a marker. After a short period of time, the markers will explode (dealing more damage if you get hit by them), after which it is safe to go to those tiles again.
