Battle System Experiment

All skills have a cooldown time. 
Most basic skills have a warmup time. Ie, they become usable later in the battle.

Cripple - lowers physical strength. Although it does not prevent the use of basic physical skills, 
nevertheless it does lower their power.
Similar logic with Disoriented and Fuddled for elemental and arcane skills respectively.
