At what point does this kick in

Last night we had a weird thing happen. I'm sure it's been asked before but I can't find the answer.

I had a Gaki with 2 wounds attack and kill a Dead Marshall. The Dead Marshall uses his slow to die action to strike back and kill the Gaki. The Gaki then uses his slow to die action to strike and kill the Judge that was also in combat with him. The Judge then attacks an Onryo there and misses.

At what point can the Gaki use his (0) ability to fully heal himself since his melee strike killed the Dead Marshall (and actually the Judge too)? Would it have been before the Dead Marshall used his slow to die or after (I'm thinking after.) Would it then happen before or after the Gaki's slow to die action?

It kind of made our heads hurt since it was a (0) action and not a (1) action to have him heal.

Yeah he can't use the (0) action to eat the Death Marshall as he doesn't have a (0) AP to spend before he falls over dead. You could choose to spend the (1) AP you get from Slow to Die to eat a Corpse Counter, but if you did that you couldn't attack with your Slow to Die action.

Gotcha
