Test-dummy Enemy

I am looking to capture spell graphics from ff6 in a similar method as the one described in this post but would like to hack a monster to be effectively/literally invincible, but unable to attack, or barring the ability to disable attacking alltogether do it to a weak enemy. This way I can capture multiple animations in one go without having to re-find the test enemy.

You can give your enemy 65535 HP and make him absorb all elements. That can be done with FF3usME. That should give you multiple turns to capture the animation. Also, a blank enemy script should make him not attack.

That should do the trick, thank you! Is it also possible to change encounter rates in order to force this enemy to be the only possible encounter in a given area?
