SOMEONEMAN'S PROFILE

I'm looking for a way (scripting or eventing) to make it so that when a character uses the Defend command, a spell is cast that depends on the equipped shield.

For example, if the character has a Holy Shield equipped and then guards, the entire part's HP is healed. If the character has a Wide Shield equipped, then guarding will boost the entire party's DEF slightly in addition to giving a large DEF boost to the defending character.
