While the 1750 reward of a +2 stat tome may be nice for new(ish) characters, it is not helpful for multilife TR projects.
I have seen suggestions in years past about making the tome BTA instead of BTC. That is a worthwhile idea for players who want to start a new character or improve on another, but still a TR project player might want to do something for that character.
How about a +1 or +2 skill tome? I think 2 is better, but 1 might allow one to clear all those skill tomes upgrades 1 to +2 of w/e that are taking up bank space.
