Raise Zombie of Slamming + Violent Dead

Does Violent Dead work with Raise Zombie of Slamming at all? I have a few Violent Dead stashed in Standard, but there is no change to slam recovery speed on tooltip, and I can't really see any difference.

Raise Zombie of Slamming Gem at level 26 gives +100% recovery, so slam drops from 6s to 3s cooldown (6/1+1). This works, and can be seen in game.

2 active Violent Dead jewels should add 200% recovery, so 1.5s (6/1+1+2).

I don't see that in game. Is the interaction broken? Should I replace my treasured Violent Dead jewels with some Ghastly ones?

E1: Bump.

I'm using two Violent Dead jewels as well. But to be honest I see no difference. The increased cooldown recovery speed doesn't seem to be working properly. Is this intended?

Most likely they forgot about those jewels since they are legacy jewels and didn't connect them to the alternate gems, internally so the interaction doesn't work.

You should file a ticket about bug in the proper section.
