Though I'd type a few things about will power for you guys. The way Kimi was talking about will power sounded a bit more like base will spends: "Once per scene, you can spend a single point of base will (or more if you're supporting a Motivation) for one of the following effects:"
Immediately gain 10 willpower points
Increase the width or height of any roll by 1
Add 1wd to any pool
Keep yourself alive (but comatose) for 1 hour even if you've taken fatal damage
Negate the penalty for a failed Trauma check
Negate the effects of mental control or coercion, or a mind control power
In certain circumstances immediately improve/gain a power (I remember you guys talking about this one)
Base will can only be gained through spending XP.
Willpower, on the other hand, is gained in several common ways. The biggest is that if you're below your base will, you gain 1 per night. You also gain 1 if you roll a set of 10s naturally (no hard/wiggle dice). You also gain it for chasing your motivations/passions and defeating bad guys. Basically, you tend to always have a supply of willpower, and probably have some spare. You're not expected to always use it, but a couple points per session would see you neutral a lot of the time.
In the right circumstances, you can gift willpower to another player
Spend up to 2 WP to gain +1 dice per WP on a roll
Declare like your sense is 1 higher
Reduce the width of a power against you by 1 (stuff like mind control)
Turn 1 killing to 1 shock or 1 shock to 0 shock when you take damage
Stay alive for 1 round
In a similar vein, there are some rules for getting extra dice. If you take extra time you get 1d per time unit up to 2. If you're not under threat, you can use the extra time to reduce the difficulty of a task by 1 instead. People cooperating on a task start with the largest pool and each additional person adds 1d to it.
Between cooperation, extra time, and willpower you can really shore up some of your weaker power/skill pools. Or if something is really important/hard you can get an edge.
