i had a look on a different website, and they say to cast bad breath on it… but i tried that 6 times, and every time it missed….. and then i died(for like the 4th time lol) its kinda frustrating… am i missing something?
Hopefully Zidane has a powerful weapon at that point, so have him attacking (using his skills like Thievery will also help – although Thievery works in relation to how much Zidane has stolen from enemies) as well as using his Dyne Trance attacks when they become available, and have Quina as the medic for the battle. Have him/her cast Mighty Guard immiedately, and then heal with potions if needed (although they may be somewhat ineffectual. Having Auto-Regen also helps a great deal). Most likely though it will turn into a slugging match between the boss and Zidane, with Quina KO’d.
As the Earth Guardian is undead, throwing curative items at it also helps (although I can’t remember if a Phoenix Down or Phoenix Pinion kills it in one hit though…). Also, because the Earth Guardian is classed also as a flying enemy, use Quina’s Twister Blue Magic spell, as it should cause quite a lot of damage.
everything enyone said helped me, so thanks heaps. i beat him in like 5 minutes. maybe it was just bad luck previously…. oh well thanks anyhoo.
