===Crippled===
Your opponent suffers from an injury to one of its leg or other appendage used to move. When crippled, each movement square count as double.

Crippling effects are not cumulative. An opponent suffers only the worse crippling effect and totally ignores other crippling effects. Crippling effects are cumulative only if they are done in the same strike, i.e.: with two total successes, you could cripple your opponent for a x3 multiplier to movement square.

Only creature with discernible appendages that are used to move can be crippled. Oozes and incorporeal creatures are immune to crippling wound.
