Patch Notes: Revenants flee

Revenants

A beaten revenant of rank 1 or 2 now usually breaks and runs, and it really gets away. Before, every flight was run down and it knelt every time, so killing you was almost the only way a revenant grew stronger. Now escaping is the usual way.
A fleeing foe now sprints at twice its walk, which is faster than a player running at average Speed and Running. A fast runner, a bow or a spell can still bring it down.
Fixed: a foe that broke while circling you used to keep circling instead of running away.
From rank 3 nothing changes: you still break its will to make it kneel.

FLIGHT-FIRST: young revenants run and get away instead of kneeling every fight by @Lattymoy in #675
