Replenishing
From Talisman Wiki
Characters may recover spent fate by replenishing or gaining fate.
Fate is usually replenished as the result of encounters from Adventure Cards and board spaces.
A character may only replenish fate up to his fate value.
Additional Rules added with The Woodland expansion:
When a character gains or replenishes fate, he must choose to place that fate with either its light side or dark side faceup. If he gains or replenishes light fate, he must place the fate with its light side faceup. If he gains or replenishes dark fate, he must place the fate with its dark side faceup.
