Secrets

Instantly kill enemies
First you need the Vanish spell and the Doom spell. (X-Zone could also work) Cast Vanish on the enemy and then cast Doom on the vanished target. This also works on about 95% of bosses!
Easy Level Ups
Note: you must have a turbo controller to do this trick

When you make it to the Lete River, set your window commands to "Short" and switch Banon’s "Health" and "Attack" then switch the commands back to "Window" so you can have Banon’s Health as the default command. When you get to a point where you have a choice of going "Straight" or Left set your controller to turbo and tape down the A button. Leave your game on overnight and you will likely be around level 50-60.
Save Cid
When you’re supposed to catch some fish for Cid, be sure to catch the fast ones that moves around in the water and give those to Cid so he can live. If you catch the slow ones and feed them to Cid, he’ll die because the slow ones are the sick fish and the fast ones are the healthy ones.
Save a Character (spoilers)
As the world is collapsing on the Floating Continent, and you have six minutes to get off, make your way to the very end where you can jump down to the airship. Instead of jumping, wait and do not move. When there is five seconds left on the clock Shadow will appear and jump down to the airship with you instead of dying.

Glitches

Get lots of items
When you have Vanish and Relm, go into battle, have one other character cast vanish on a desired opponent then have Relm Sketch that opponent and QUICKLY run away, check your items and voila! *Note, may not work on all carts. 1/1000 chance of freezing the game.
Another Game Glitch
Put Gau and Relm in the same party. Have Gau jump on an opponent. Fight until he comes back, but before he does his little speech, have Relm sketch him. If your game is glitchable, then there is a chance at switched up character sprites and/or many items added to inventory after the battle. I recieved 255 MagicBoxes and 255 Atmas Weapons this way the 5th time I did it. (Note this only works on the early carts. Will not work on all carts.)
Evade Glitch
On all versions of the SNES cartridge, the evade% stat has no effect.

All algorithms use MBlock% to calculate dodging/blocking an attack, magical or physical.

128% is where MBlock% is maxed at effectiveness (higher isn’t worse, it just isn’t any more effective)

Therefore, equip your characters to 128 MBlock% or higher and you’ll be nearly invincible (block or dodge any unblockable attack.)
Psycho Cyan
In a battle, have Cyan use Retort, then cast Imp on him. Then use an attack that kills him without triggering Retort, such as magic, or killing him in one hit. Now revive him and use the Fight command with anyone. Cyan will counterattack every move that is made, including his own. In other words, Cyan will attack his enemies over and over again, uninterrupted, until they are all dead.
Double Mp with Runic!!
Equip Celes with a Cursed Shield. If she absorbs (with runic)a spell the shield makes her weak against (fire is what i used) she gets back double the mp of the spell.
Save anywhere in Kefka’s Tower
First start by getting one of your groups onto a save point. Now cycle through the groups until you arrive back at the one on the save point. Switch groups one more time and go to the party screen and the "Save" command should be useable (and you can even use Tents!). Even after walking around and getting into a battle, the Save command should still be available.
