Not sure if you can change stats on the fly, without respawning the character (I've never tried, but I remember hearing iffy things about changing stats mid-game).
If crpg uses/ has an equivalent to the damage, speed and HP operations from 1.153, you could apply a boost through those on the fly.
Something like a 10% boost would be cool, as your character's build would still be the core of what you become (magnified).
PS: Impressive necro!
Couldn't you have coded it yourself by now
?
