Your best bet is to attack with Magic. Steel Giant has a weakness to lightning, so be sure to have a couple of characters with Lightning above levels 3 or 4. The others should be the healers of the party. Steel Giant can hit inflict a very high amount of damage. After the battle, this enemy might drop a random Genji item, Aegis Shield, or Excalibur.
[view·edit·purge]The mythology and legends of many different cultures include monsters of human appearance but prodigious size and strength. Giant is the English word, coined 1297, commonly used for such beings, derived from one of the most famed examples: the gigantes of Greek mythology.
