Just FYI, as I had to check it out first. All classes will use the stone of wise for one of their skills to use. If you think about it, after the fact, all stuff sold in the open market by an NPC is usually for all. But I checked the Titan +100 skills and saw a skill that had to use the stone of wise.

But then you have to be a level 132 RK before you will need the stone of wise. You use it for the Aura of Accuracy which is a party buff. The buff lasts 30 minutes (1 hour game time = 2.5 minutes real time. So 30 minutes = 1,25 minutes real time). Then it costs you 2 mill, 3 mill and 5 mill for each level. The level 140 buff SOUNDS good, cuz it says it gives party members 500 HR increase. That is nearly the equivalent of the HR for 3-ToK which is 498 hr. With the 3 ToK that i got, at level 112, i got something like a 650 hit point damage increase now or about a 6% increase. But then 5 million gold a buff for 1.25 minutes might get expensive now. But When i ever get up there, I will put my 2 cents in, on good or bad for the buff.
