Hey all! So I've been grinding for a while now trying to obtain every unique boss weapon, and I've learned a few things along the way! The following tips are on how to make the boss fights themselves quicker and easier. Enjoy! P.S I'm advising under the assumption you have end-game armor/weapons. Erchius Horror Let's be honest, if you can't beat this boss with end-game armor then you've got other issues than not being able to get the weapon. With end-game armor, you can run through them beams without a problem. Easy as pie! Ixodoom This boss is also pretty straight forward. However, I found it was easiest to use the Doomcannon because each shot will hit the Ixodoom [because of its large size] and Nuru is constantly hitting it [when the Ixodoom is doomed, Nuru's attacks will do MASSIVE damage] Asra Nox I reccoment grabbing a Asuterosaberu DX, because Asra has low health but deals high damage as you fight her longer. You can end the fight after the first phase of attacks [after the first morph ball attack] with the DX before she has a chance to use her more powerful attacks. Kluex Avatar I'm gonna be honest, I don't have many tips on this one. My biggest advice is to grab a sniper rifle and hit from range, because melee takes a long time to hit in the second phase. Big Ape Big Ape's most damaging attack is the laser spray he does after each sentry is downed. This attack is easy to avoid if you equip the wall-climbing morph ball and stick to the wall when he is shooting lasers. The beams are more spread at the far sides. Bone Dragon Two words: piercing shot. Get a sniper rifle with piercing shot, sit at the front gate, and the cultists will line up nicely for you to get 10+ kills at a time. As for the dragon, it really isn't that bad if you use some flame antidote.
