Hunters: Grab a Handgun and a good Saber and/or Dagger. Use that
Handgun to aim and shoot at the feet until its head comes down. Switch
to either your Dagger or Saber and keep smacking the head. The Dagger
might be your more powerful weapon at this point. After the Dragon gets
smart and keeps its head up, use the Handgun to hit the feet and use the
Saber/Dagger while it breathes fire.
Rangers: Grab a Rifle and a Saber. Smack the feet with the Rifle
till its head comes down. If your Saber is more powerful, use that instead
on the head. After that, just gun the feet for the duration of the fight.
Forces: Grab a Handgun and a Saber. Make sure you have Barta on
your main configuration (when you don't have to hold down R to use it)
and Zonde on your secondary configuration (when you do have to hold down
R). Keep casting Barta until the head comes down. Now find out if your
Saber or Barta is more powerful than the other, and continuously use it
against the Dragon. When the Dragon flies up, pelter it with Zonde spells.
Resume with Barta when it walks on the ground.
Hard/Very Hard Offensive Strategy:
Hunters: Use a Slicer! It'll hit 4 parts of the body for greater
damage. Don't use Swords or Partisans.
Rangers: Use a Shot! It'll hit 5 parts of the body for greater
damage. Keep using it for the whole fight! Use a Rifle-type weapon if
you need to.
Forces: Use Gizonde! Avoid Gibarta! Gibarta wastes TP while Gizonde
hits multiple areas.
Ultimate Offensive Strategy:
Hunters: Same deal as before.
Rangers: Same deal as before.
Forces: Use Foie, and avoid Gifoie! Gizonde still works here.
