A similar question as the previous poster, can you choose an area effect shtick but not use the area effect?
For example, using PPI against monster strong against Elan (mindless) like a normal shtick to get rid of them and then continue fighting since you didn't use the area effect.

A separate example like the fireball one above, if the first monster has a defence of 6 and the second 20, can you choose to just attack the first one?
