Reward: Jack of Blades hero doll.
Hero dolls can be found in various places, but in most cases you have to win them in mini-games placed in all of the game's taverns. If you have at least one of them, go to Bowerstone South. You will meet a kid who'll tell you that the local teacher is quite a collector and you should see him once you have all the dolls (your own impersonation doesn't count here). There are 6 of them to get.
HINT: you will find Slow Time spell very handy in all the mini-games based on time and reflexes.
1) Briar Rose - win Card Pairs in Bowerstone South in less than 30 seconds.
2) Whisper - win Coin Golf in Oakvale hitting the coin 11 times (par -2).
3) Twinblade - win Spot the Addition in Twinblade's Camp in less than 25 seconds.
4) Scarlet Robe - win Card Sorting in Knothole Glade in less than 25 seconds.
5) Maze - win Shove Ha'Penny in Hook Coast scoring as high as possible.
6) Scythe - win Coin Golf in Snowspire hitting the coin 10 times.
And the reward will be.. Jack of Blades Hero Doll. I hope you didn't expect anything better. It's pretty useless, you know.
