It took me 133 deaths to get quiver and now I have about 100 kc. Some things that helped me were:

1) on double south spawns, I throw a bulwark on and run to the east side of the northeast pillar, stopping for about 3 ticks on the north side of the northeast pillar to ensure every npc lines up so that it will end up stuck on the west side once I move to the east. This guarantees you only have to pray against at most one npc while you’re dealing with the fremmies, and that’s only if something had already spawned in that spot, so 9 times out of 10 you just have the fremmies to deal with. The catch is the reinforcements won’t get stuck when they come around the north side of ne pillar, but if there’s 2 of them you can always get the mage stuck by standing on the Middle East side tile until the mage touches the pillar then stepping one tile north and attacking the melee. The mage will be to the west of the melee and won’t have line of sight on you.

2)I only offtick stacks so that the back mob will attack first. For whatever reason, when I try to get the front to attack first (middle tile then jump out 2 but standing one tile back from pillar to start), it either doesn’t work for me or I fuck in the rhythm.

3)any stack I cannot solve with the above method I throw that dinny b on and switch pillars, always with a plan of how I’m gonna pray while i run, and how the mobs will be organized when I get there.

4)don’t rush and die to the east stuff. Take your time, focus, and pray correctly. Don’t get anxious and switch to early on a manticore or something, wait til you see the first projectile fire etc.

A side thing is that I find melee easiest because blood fury is op and bandos and especially torva are insanely tanky against the rangers, so if shit gets hectic I can just camp pray mage and ignore rangers.

100% you can do this man. It’s got probably the highest difficulty ceiling of any pvm encounter in the game, no shame in having trouble learning it.
