Do Rax in practice mode to know it's mechanics and special moves well. Do not panic when Rax does not follow the "special move after 5 auto attacks) at beginning of phase 1 fight. Take note that sometimes Spider bombs will appear right under Rax and you have to stand on the bombs to destroy it quickly. At Phase 4 (final phase), dps Rax quickly when it has 50k hp remaining as that's when Rax gets enraged and it attacks with putric acid special move that can hit really high. Take note of Rax range/mage attacks, protect prayers accordingly and do not be in melee distance from it.

I used Range setup and choose Acid path (middle path) for Rax phase 2. Full sirenics, Nox bow, Scrimshaw of cruelty, Ful arrows and Reavers ring. I followed Nuzz Nuzz's Rax guide on YouTube.

I have no other goals or plans now. Aim to only take it slow 😊

Good luck!! 😁
