A simple system for everyone.

Admirably simple resolution mechanics. The only suggestions I could call to mind would be to provide renamed abilities in some cases;

DeProtect --> Sunder (removes Protect defenses, increases physical damage taken).
DeShell --> Shatter (removes Shell defenses, increases magical damage taken).
Imperil --> Vulnerability (Specified Element) (specifies which increased elemental type of damage taken).
Zombie --> Inversion (swaps all vulnerabilities and resistances, which could work for better or worse).


In addition, some possible other (rare and powerful) conditions to consider.

Dazed (cannot take magical offensive or defensive actions).
Stunned (cannot take physical offensive or defensive actions).


Short of that, very simple and effective in the hands of fair and well mannered users.

A simple system for everyone.
