Doryani's and Berek's grip leech stacking

I've got a CoC lightning/Cold build that uses Doryani's catalyst, invitation, and Bereks Grip.

+ 1% all elemental for doryani's catalyst
+ 1% leech on cold from invitation
+ 5% on frozen monsters

Will I get 7% leech if I hit a frozen monster with a cold spell? Does anyone know how life leech stacks in this situation?

Leech is Leech. All the aforementioned Uniques grant Life Leech, just under different conditions.
Leech always stacks additively; you get 7% Life Leech.

Thanks. Thought so. Wasn't sure about conditional leech.
