Don't think Mack actually needs a breathing mask with his Stormtrooper armor and helmet. But it don't hurt to have a spare for the prisoner we are rescuing.
Having been around the block a few times (PbP wise) now since I started this game, I have seen a few different ways some DM/GMs do Initiative. Might I offer a suggestion, Possum.
In between combats, why don't we each roll 3 Initiatives and you save them in your GM notes or here on the OOC thread. That way we roll them and you don't have to wait for us to roll right before combat starts. Then after you have used them up, we roll 3 more.
Another question. How do you feel about using JC 114?
