So I was doing One Small Favour, and going along fine (apart from having a hard time finding a white-robed, white-caped Seer in a bunch of white buildings), until I got the scroll from Cromperty. I wasn't expecting a big fight at that stage, so I ran off to get food and armor and the like. Coming back, using the Incredible Reflexes prayer (though not, I think, Ultimate Strength; I forget why) I was hitting occasional twos. I got the Slagilith down to a bit over a quarter health when it suddenly lost interest and turned inanimate. My question, therefore, is how do I do more damage more quickly? Please don't say "grind strength"; I hate grinding. For the record, I have 55 in each melee stat, 48 prayer, 55 magic, 51 ranged, and 39 summoning, and am using Excalibur as my primary weapon.
