Completed with minimal stats! This is my guide to colosseum waves. Credits to people like molgoatkirby, gnomonkey, aatykon, ReynoldsWrap, and others who showed me a lot of the tech throughout this video.
Wave setup: maximize prayer bonus, bring tbow or shadow with minimal melee switches (only bring accuracyincreasing gear, the rest doesn't matter), 10 restores, 9 brews, super combat.
As simple as that.
