So I've got about 20 fire capes in the past but just got back from a break and got fight caves as a slayer task and I haven't done it since tzhaar update and flasks and gano armor and things like that, so what would be best invy and gear to do caves, gano armour and poly staff or melee and rapier/claws or something else, and is there a good vid that can show how to tell between jads mage and range attack since they were updated, thanks :)

The Tip.it Fight Caves Guide should answer most of your questions. To see the attacks try Youtube.

Use polypore, bring 3 overload potions (4), 3 renewals and about 10-12 prayer pots. Also bring eee and about 8 brews, you wont end up using any brews until Jad. You now have to lure the healers away from Jad to stop them from healing him. Ahrims should be fine for the caves, switch to Gano for Jad.
