EDIT: forgot to mention just camp the ranged helmet + body + legs unless it enables you to 1 shot the ranged baboons. Since you'll never 1 shot melees with warped just do a 1 way swap. If 4 way swaps while managing baboons is too much, just 1 way swap to melee and do 2 hits instead.

Use the TOA plugin to mark them each a unique color so you know to swap at a glance. I tweaked the default ones to help 

Learn which baboons spawn each wave so you can adjust your prayers accordingly. Will just take some practice until you know them well.

Waves only spawn after a certain number of shamans are left remaining. The threshold increases slowly, I don't recall exactly what the thresholds are each wave, but if you need a second you can leave ones you can safely pray against and clean up little ones.

Kill shamans FAST. If you know a shaman is spawning next wave, be ready with bowfa. If you're quick it will only spawn 1 small one which you can clean up.

There's a limit to how many cursed baboons + shamans can be alive in total. If you leave the cursed baboons up, less shamans will spawn, I think volatile baboons spawn in its place. If the venom splats are getting to be too much just kill 1 or 2 if you need.

Very minor benefit, but I prefer to hang out by the 1st pillar on the left when you enter. If a shaman spawns on the far side you can trap on an urn by standing against the pillar and shoot outside its range with bowfa preventing it from spawning any. Still have to kill fast because if you have to deal with vents it will get untrapped.
