Out of all the quest reward cards that Sacred Pools introduced, 4 really stand out to me as amazing:

Might of Giants: Increase your Strength value by 1

Chant of Wisdom: Increase your Craft value by 1

Ironskin Charm: Increase your Life value by 1

Good Luck Knot: Increase your Fate value by 1

A question arises for me, though. Does increasing the base value of these stats also mean you gain a corresponding counter to them as well? It doesn't seem like that's stated. Might of Giants and Chant of Wisdom would of course effectively gain you a counter if your current total in either of those stats were at the base value (as you can never go below that number in these stats), but what if you were already above it? Would a character with a Strength value of 3 but with 5 total strength who draws Might of Giants be at 6 strength? or would he simply be at 5 strength and have his value increased to 4?

Ironskin Charm and Good Luck Knot are for stats that CAN go below their value, so do they gain a counter if they're below? Let me know what you think/know!

I should say that it increase your power or craft by 1.

So if a strength 4 value becomes 5, and you have 2 counters, then you have strength 7

Good point, I see the logic there. I get confused I guess because when we play we assign counters to the points of strength or craft granted through the stat values. So if a character has a strength value of 3, we go ahead and assign 3 red cones at the beginning of the game to him to count that (I realize this is not in keeping with the normal rules, because we didn't realize this at first and it's become a bit of a habit). Going by the rules though, where you use counters ONLY for the strength and craft beyond the base values, this makes sense.

Life and Fate, however, DO have their counters used to represent their values as well as any additional points in them, but I suppose the same rules apply to them for these quest rewards.

Also good with warhorse and those spells that double a stats value..

not only they sound really powerful (not only for warhorse or monk: consider also all those effect that restore your life to your starting value!), but AFAIK they are the first game effects that tweak the base stats, arent' they?

yes I believe you're right
