Culling Strike and CI

I'm under the assumption that Culling Strike is ineffective against CI players, but as I was just in the Hall of Grandmasters and died with 1k ES left maybe it works once CI players are under 10% ES?

Right, it shouldn't work, you're always on full life with CI. Are you sure you weren't just oneshot or took a bunch of damage at once?

Yeah, if you were culled it was a bug, but I haven't heard any other complaints. You don't have a caustic mana flask do you? Or maybe an item that does damage to you. I think there's an item that somehow links you and your minions so you can take damage wearing it. I haven't played darkshrine, but if that's where you were maybe it had something to do with that.

I was dead and still had 1k es left covering my health but I was 0/1 for hp.

Edit: I don't have a mana flask and didn't have a minion out at the time. No shrine effect was active.
