Taken from here: http://www.tip.it/runescape/?max_hit_calc At 99 strength, with 1/99 hp, potted, praying, D-baxe special, activated Salve amulet(e), agressive style, Full Dharok's and all strength boosting equipment you get a max hit of 90. Thats amazing, but very difficult to get and very unlikely. With Keris, 99 strength, maximum strength boosting gear, potted, praying and a D-baxe special you get a max hit of 33. If it does the special (Triple damage I think) thats a max of 99.
