Setup
Keep in mind you can probably do it with gear even worse than mine and you should obviously replace the row (i) with seers or whatever, I was just too lazy and don't have a better ring..
Inventory
I honestly don't even use those brews I might use 1 or 2 if things get buck wild but you generally heal enough to not need food.
1 - 63
1 - 31 is fairly easy you just want to prioritize the npcs in the order of Xil> Mejkot> Kek> Kih I try not to use prayer as much as I can help it usually until around wave 21 or 22 is when I leave pray up
Pay attention on round 29 cause that is the wave I end up taking the most damage on every time it has a Mejkot and 2 Xil just make sure you're praying melee and kill the Xils first
31 - you basically pray mage the entire time until you get to wave 63
Wave 38 is when Mejkots, Xils and Zeks spawn, I always kill Xil before the Mejkot because the Xil should die before it does any real damage to you and you should be able to outheal the damage Mejkots can deal alone. Worry about this until round 45
45 is A Zek and 2 xil which is another wave that you want to watch for
I don't really know many tricks to any safespots or any of that I normally just go to the spot in the picture and focus the Mejkots which spawn in the red circles and kill the Xils that spawn south of me on those waves
Jad Wave (No healers)
Protect from MAGE when he crouches down and leans backwards.
Protect from RANGE when he lifts both of his front legs straight up into the air.
I needed help with my first Jad kill but I have done the fight caves twice like this on my own for the achievement.
(Shout out to 52xp lol)
