-Lose 5 unspent Ability points to gain 1 Attribute point
-Lose 1 unspent Talent point to gain 10 Ability points
Add these together and there is no reason to take All Skilled Up, Bigger and Better, Light Stepper, or Know-it-All ever again. And Politician and Scientist are very dubious investments indeed.
(Well I kind of knew that before, except for Light Stepper. That one was a little surprising.)
All skilled up is available at level 3 where 2 abilities point is really huge. For a third of the game it's a decent talent. After acquiring moloch of course, it should be respeced away and never be picked again.
That's a bit far fetched, but it can have its use early game. Still, maybe it would have been simpler if it just gave a straight 2 abilities point + 1 ability point every other odd level up?
Scientist may be worth as much as 6 ability point for henchman or 4 ability point for pragmatic main character. At least it scales better than the current all skilled up.
