The easy way to beat Rajang is to watch his moves carefully the first part of the fight it will tend to throw punches they are easy to avoid punches just walk passed him. 🤷‍♀️ if you can time it you won't get hit as much.

Watch how i can avoid all his attacks this can be done very easy with a Heavy Bow Gun Builds of course we all love our Sticky builds 💥
asides that ice weapons work so well and blast damage types tendering the arms are the main area you want to attack as the tail doesn't need to be tendered. also on his third stage of Rage mode when he leans forward hes going to ground pound which can cart you if your not careful! to avoid it turn away from him and run once hes about to hit the ground Roll and you should have no damage taken at all.
