How a bout JDA call it now, he'll act on the next Init phase at the earliest. And they could assist Sam with the guard near the doors? (That way you could have another guard down by the end of the next IP.)
could work, but i fear that the spirit would not make it in time, materializing is a complex action itself and spirits are not as fast as I or may be even the guard is. He may thou get the ambush so it all depends on how fast he is, cuz i will be able to make just one more shoot and then i will need to relode
opening the door
1st shoot
ini pass change
spirit materelizing
guard suprised no action
2nd shoot [guard is able to dodge]
reload
guard/Spirit? who will be faster
I was thinking to take the full effect of the ambush round, but if we hurry it it can end a bit worse. as if I would only attack SA mode in the second phase
combat turn is 3 sec so opening a door for that period would be a risk to lose the surprise, but thus far there has nothing happened that he knows of, so there should be no way he expects an invisible man coming in shooting.
the same "who is there situation" just without attacking in the back.
p.s. my taser has 4 dart clip and I have shoot 2 already.
