Hello, I'm recently returning to RS and I got a task from my Slayer Master to do Airut's. This is a new creature to me so I have no idea what the setup for it should be or what I should use. I'm 99 in Str/def/att/const, 97 magic and 88 range as well as 92 slayer. I dont have a ton of money to spend on gear. I have around 5.8m at the moment. I also have Slayer Helm, and I just a regular pair of gloves as I don't have any good ones currently. I also have a Vine Whip, multiple Dragon Defenders, and Korasi's sword. 

Honestly, I would recommend you skipping them. I'd say you definitely need at least level 80 weapons and a solid form of healing either through a unicorn or soulsplit is a must, otherwise you're going to be eating a lot of food and banking a lot.
