use your meteoric boots for the aura. also get rid of the poison brace and get a physical dmg one/ aggy brace/ energy regen brace. same goes for your other brace. also try to get a comrak set at lvl 140. if you dont get one buy a dmg or a bat charm. idk what rings you are using but i hope a ss/riposte/ls ring or something like that. if you like the dagger stay with it and if not get an axe and a haste ring
No, the aura doesn't speed up the levelling process nor is it any good.
He should get a damage helmet, scrap the haste dagger and get a slaying dagger and haste gloves. Yes get rid of the poison brace and get rid of the red one whether that's heat or hp regen. Hp is regen is not valuable, get an energy regen brace and buy a physical damage brace or a nooby wyrm one(just ask any high level I'm sure they've killed wyverns enough to own some) and pick up a kron's(level 90 I think) charm for now. They do suck but it's better than leaving it empty.
Don't say you can't afford it, you asked for advice. Farm for some cash is all I have to say.
