Some info on Dagannoth Kings: http://runescape.wikia.com/wiki/Daganno ... Strategies
Basicly, you need all 3 styles of combat triangle to kill them. Each Kings is vulnerable only to 1 style and immune to others.
It is also advisable to take a yak to bank the bones and hides and other stuff which they drop a lot! The rewards are fairly good . Some of them: Dragon hatchet 800k, Berserker ring 380k, Seers ring 174k.
According to Wiki the drop rate is up to 5 mil/an hour... well.. let´s see if it´s true
If you don´t have a yak, take those magical papers that could note your stuff or just another BOB to hold the hides and bones. ( hides are 3.6k and bones 6.4k, so they´re worth picking up).
As you need all 3 styles you can change your armour or just use some hybrid (Warpriest of Zamorak/Saradomin armour).
If it´s your first time, don´t hesitate to come along or pm me if you have any questions !
