I decided to run a little comparison for every ten levels, to see how much XP/Hour you need to gain to have Wisdom aura beat Jack of all Trades' Strange/rock per day XP. Seeing both can be done in the same amount of time, it gives a clear reading of just how much XP you need to have Wisdom be worth the trouble (over JoaT):

 

 

Additionally:

 

Lv. 110 - 11,980 - 958,400

Lv. 120 - 14,260 - 1,140,800

 

 

So yeah, at lv. 80+ all you need to be able to earn over 507,200 XP/hour for Wisdom's bonus to beat Jack of all Trades' bonus. Have fun with that.

The Reward book from Jack of All Trades is bankable, and stacks in your bank.

 

<3:

Wow nice, so I don't have to worry about getting levels up for doing tears of guthix (don't want to level up the skills i want to do ToG with faster with those tomes because then I would have to train other low skills first :P ). Still JoAT is not at the top of my list.

Never mind about it stacking in bank.

 

I have the Reward book banked, and when I went to activate my Aura today, it politely told me:

 

You must claim and use your reward from the Jack of Trades aura before you can gain another.

 

-.-

EH, that is a bit of a bummer, but not too unexpected. We seem to already have entirely way to many bankable exp methods now a days anyways. <_< ...(though I still have loads of Trek tokens/tombs as well as effigies banked...irony much right?)

 

Ive also seemed to notice most blahblahblah "books" aren't bankable. Where just about everything else seems to be. I guess that seems to be stemming from the "it was only meant give you 1 per x timeframe, so use older one first."
