how to encounter warmech(?)

[Black Mage FF1]

I'm going to again reccomend being at a HIGH level for this fight. Not only does he have more HP, he regenerates every round. I'd say level 34 all around MINIMUM.

Minimum? That is an extremely high lvl. WarMech is easily beaten on both versions at lvl 27 or less. Unless you are using a weak party, like 4 thieves or 4 White Mages.
