I’m not sure it is a bug but I wonder if Multistrike is working as intended.
First, I’ve seen one of my skeletons being killed by the second hit of a Multistrike, but I had a Pegasus in my team. I think the Pegasus should have intercepted as least the killing blow but I’m not sure.
Second, I wonder if the following blows of a Multistrike should proc abilities and effects ? My Fallen Carnage procs its abilities when killing a creature with a following blow so I believe the answer is yes.
