Got a tip from Flame last week...for the new invention skill, it's going to be about combining gear (as Mod Mark introduced at the recent RuneFest), so he bought 1-2k of whips when they were still dirt cheap. They skyrocketed for some reason after special attacks announced, and I think they're going to rise again when Inventor or w/e comes around.
Also, we've all heard energy is going to be used for it too right? I have about 40k incandescent energy (the last tier one), worth 4.4 ge mid right now, but I'm torn between using it to get 99 faster or maybe saving it and investing in buying some more...opinions?
edit: Also, getting keys at the Ascension dungeon is good ranged training and moneymaking as well. Just now, BPN got 8 keys in 45 minutes for a total profit of 5.3m, including petty drops he alched.
