#Script: Limit Break 7

=begin
This is a rather basic implementation of the Limit Break system from FF7.  To
use it, start with the settings below.  You create a skill category much like
the default Skill/Magic, and place it's number in TYPE_ID.  Then you create
skills in said category and have your actors learn them.  They don't need to
have the "Limit" category under features as the command will appear on it's own
when the conditions have been met(Full TP gauge).

Also of note, any skills placed in your "Limit" category will automatically have
it's TP cost equal your current TP, or max TP since you need it at max to
access the command.

Finally, the Limit command will only appear to actors/classes who have the
notetag <use_limit_break_7>, or are equipped with an item/state that has it.
