A blade dancer in the battlefield.
During flight, Fanny deals 10%-20% extra damage to enemies hit (scales with flying speed) and applies a stack of Prey Mark to them (up to 2 stacks) on each attack. Her subsequent skill hits on marked enemy heroes restore 8 energy per stack for her. The energy restoration is reduced if she hits multiple enemy heroes within a short period of time.
Fanny counters squishy heroes that lack targeted CC like Karrie and Irithel who cannot stop Fanny's extreme mobility while she bursts them down.
Fanny is countered by heroes that can restrict mobility, such as Kaja and Khufra, since they can easily shutdown her main advantage.
