Please change the Favor tome for achieving 1750 favor in an upgrade tome (x)->(x+1). Base value +2
Let the game check what tomes you have used. For each stat you will recieve either a +2 if none or +1 taken or an upgrade tome, pushing it one step further until the maximum is reached.
Im getting sad each life when i have to kill one of those.
I think it would be a good way to make the favor worth again, even for vets.
If you think it is too powerfull:
no tomes used: 24 lifes for all tomes to max
only +2 tomes used: 18 lifes to max.
It should be save to assume the avarage time is still about 10+ lifes
Should be worth smth.
