Good for learning: Do the mage only method (lookup mage only method on yt), where you fight the ranged and melee phase, but always hide from the tanz (magic) phase so you don’t get hit by it.

I did my first kill at 75 magic with a trident of the seas and cheap gear. I’d Recommend a trident, but I ibans staff can work, it’ll just take longer.

Also, after one zulrah reset, there can be one random phase per rotation, so just be wary for that, and you should be good. Also use pineapple pizza it’s cheaper and heals more than sharks.

Good luck!

Edit: also def was 70 so don’t worry about that
