Doesnt Mind Flayer do damage?

My memory is probably flawed, as this was ages ago when I hacked them into my inventory. But I think it did 1200-2000+ damage and it probably stuns them too.

In FFIV Advance, on my new file, I obtained Goblin at the very start of the game, while wandering levelling Kain and Cecil. (I know that any levelling at the start of the game is near pointless, but I like doing these things)
