Spy Action

Spy Action determines your ability to use spies offensively. Higher spy action increases the likelihood of a reconnaisance or sabotage mission completing successfully, and allows you to see the gold of more players on the battlefield. You will be able to see players' gold on the battlefield if your Spy Action is greater than two times their Sentry Action.

Formula
Spy Action = (P + U) * 1.6^C Where P is the total power of your spy tools

U is the number of unequipped spies you control

C is your Covert level (1-15)
