Unlike most other characters, Rinoa has two different types of limit breaks. The first one (combine) consist of hitting the opponent with physical hits, while her second (Angel Wing) uses the power of magic.

Rinoa receives this limit break the moment she becomes a sorceress. She doesn't have Angelo at the time, so you are capable of exploring this new attack by yourselves. Even with two limit breaks, it doesn't make it a strong limit break.

This form of attack is equall to the berserk status, you loose control of Rinoa, unless she looses all her power or the battle ends. There isn't any magic or item that has the opposite effect to gain control over her again. While in this state, Rinoa's magic increases up to five times her normal magic stat. So if the stat would be 255, it will reach the 9.999 HP of damage.

Rinoa will only use magic that she has stocked during the course of the game, but as sorceress power can go, she will copy her magic, so you won't loose any of your stocked magics. The magic she casts are mostly attack magic, time magic and status magic. She won't use any life magic nor support magic. If you happen to have forbidden magic and other magic, then there is little change that she might use this aswell.

Rinoa does not have the power to cast spells that she doesn't have stocked, so the best way to use this limit break is when you have a lot of different and usefull magic.

If you are with a boss who you have trouble with defeating, let Rinoa cast only the strongest magic like Meteor, Quake and the full magic like Firaga, Blizzaga and Thundaga. It might come in handy when she might only cast these ones, except for status magic that don't have a effect.

I didn't try this myself, but I have read somewhere that if you do not stock any magic with Rinoa, she will use her weapon to deal up damage, this might come in handy, when the monsters or boss has low defence status, but a high magic defece range.

There have occassional be troubles with casting Limit Break while under a certain status as the Invicible one, do not cast this limit break onto her, there will come a message saying it has missed target, better remove this support status in order to get it work.

Rinoa sometimes has a certain magic she likes to cast, sometimes twice after each other, the magic such as scan is used a lot and might be annoying after a while. If you really get annoyed by her, the best way is to remove the magic you don't want her to cast.

Also it's best not to spil any triple magic onto Rinoa, as she won't cast three times.
