Das ist ein optionaleer Boss und mit einer der Gründe, wieso ich nicht weitergespielt habe. xD

Gamefaqs sagt dazu übrigens das hier:

Like the Wyrm you must have a Troubador,Protector and a Medic. Every
turn your protector MUST use Anticold. Anticold MUST be at level five and only
at level five. If it's not at level 0 point will still have a chance to OHKO
you. Your troubador must Erasure at level 3. Use erasure when he uses Iceblock
or Regen. When he uses Iceblock you will probably only do about 3 or 2 damage.
Icelance will hit you even if you do have Anti cold on. Icelance is a very
deadly attack and will almost always kill when it hits. Remember to use
Immunize. Out of the three dragons this guy is probably the hardest.
