Something I've been working on for, mostly for me but also for anybody else who finds it handy:
National Action CoS Planner/Calculator
It accounts for literally any known modifier that could affect a die roll, from Personal Attention to crit threshold reductions to Super ACME unlimited. All known traits have been included in drop-down menus, and there are slots to manually put in modifiers that aren't tied to specific traits (e.g. Janna's one-off +40 to Chicken Itza).
It also shows chances of success, chances of critical success, and chances of critical failure for each action, both with and without variable amounts of XP. The type of XP applied (DC reduction, roll modifier, or crit threshold reduction) can be specified on an action-by-action basis.
(I promise I was working on this
before @clockworkchaos came out with her version.)
Anyhow, if you actually want to use it but something's wrong or I messed up the protections or something, let me know.
Or if you have an idea on how to make it more user friendly. I'm just not sure if that's compatible with including everything.
Also, a couple of technical notes:
At the moment the sheet assumes that a d100 can explode indefinitely, so if that's not how it works I'll change it.
It doesn't include Janna's "I Got a Little Bored. No Offense" trait, since that causes the action to
not happen rather than fail, and I decided it wasn't doing something special to account for it. I may come back to this later.
And if you're wondering how it works, the answer is extremely amateurish Javascript.
