you just have to find the item called "Life Tab" in the dinosaur-forest... but its a bit hard to get it, because its the rare steal from the very rare "Czar Dragn" (I heard he appears instead of the 150th Bracosaur, not sure if this is exactly right)

After obtaining, just use it either in narshe (there, you can get Biggs or Wedge back), Thamasa (Leo) or Vector (Banon)!
In Doma, you can get this Ghost called ????! The Ghost is pretty fun, I'd suggest you choose him ;-)
