A major improvement from the original composure set. The new composures included in End of the Earth are, in my opinion, auto includes. 2 constant stat boosts, 0 cost, soak, slotless, a way to spend resources you don't need, and to top it all off it doesn't even cost an action to play. All you need is a way to find it in your deck, and as long as you can protect that 1 damage/horror that will send it to your discard then it can stay in play all game, easier said for Survivors probably. Much like the original versions, I personally think moxie and Plucky are two of the stronger ones as they help protect against treacheries and can help with monsters/clues respectively. Rogues really can get a lot of treachery protection out of moxie especially if you can generate a lot of resources (and which rogue can't). And honestly, who doesn't love the art for this card? Save the puppy!

Important to note that allies and armor can soak before Moxie has to go!

Sadly, rogues usually could make better use of sanity soak than health soak. Gladly, rogues are often rich enough to pay for more will to protect against treacheries.
