I often struggle to hit the things I need to hit most of all, even as an 18 str lvl 9 PC. As the main looter in our gang, I know that we do get some favour/bless, but not many compared to all the other potions available.
Would you be amenable to increasing the rate/quantity of favour/bless potions in random loot tables?
I'm not against your suggestion but...
These are extremely cheap to brew, and now every cleric gets brew potions. How come you did not just trade for those?
My experience is that there's an abundance of Bless potions, Divine Favor is somewhat rare, and Aid almost never drops. That said, I think it's fine as is.
