Thanks.
The reason i asked was because after finishing the game for the 6th time i decided to play again in memory of the good old days and i noticed when i was fighting Sacred that my Zell who was at level 23 was unable to stock life magic and when he was able he only stocked 2 or 3 per turn and my Selphie who was at level 20 was able to stock 6 and 7 lifes a turn sometimes even 9 and i had Siren and Shiva junctioned to her and her magic power was much higher than Zellīs cause i had only had Ifrit junctioned with him and as you know unless you teach it Ifrit doesnīt know Magic junction.
