Help, for Ispen Castle

[Sepho]

If you don't feel like rebuying weaker weapons, you should be able to find some within the first ten minutes you spend at Ipsens.

I never noticed that the weakest weapons are the strongest, surrvived without problems anyway, and yes, tonberries are easy to defeat, as long as you've got Zidane in your party, he sure as hell can kick @ss! And no, you're not stuck there forever, start by beating some of the low level monsters (escape from others) and as your level grow the easier it'll get. And as SePho_zO says, you'll find some weapons while searching the castle. Good luck!

Another thing to note is that every enemy in Ipsen's Castle except Tonberries and Gargoyles can be afflicted by Freeze (or Quina's Frost spell, and as said earlier, Gargoyles are easily killed with a Soft). So in short, either have Quina with the Frost spell or Steiner with the Ice Brand sword + Add Status and give them as high a Spirit as possible. Freeze + any physical attack with kill a monster instantly.

Just bring in magic users and don't bother with physical attacks.
