They say fixed (instead of changed or rebalanced) but the game still clearly states the original intention of Vaul’s Quiver:
Amaranthe also recovers arrows each time it restores health.
@ShellaSunshine the thing that is wrong is the tool tip. No matter how much I dislike the mechanic and it breaking of the original intention.
Note that Amaranthe only recovers health up to 50%. (in case you got confused by the patch notes)
