[Conditional FX] - Multiple effects if conditions arise during cast
For example, a unit who is affected's HP drops 100, for every other unit with HP greater than 100 the spell runs some sub-spell effect, or completely copies itself
This probably sounds like it could get far too broad, but I think its validated by the fact that you'd need to be rather creative and think up a unique condition, not just some simple easy one like unit HP's
Perhaps if this theme were chosen, the theme points could be easily derive by the creativity of each effects and the conditions that cause them
