Catching Monsters Easily
Do not give Ovaseeds to your monsters. Instead,
throw them at monsters you need in the Tower to
get their eggs. The game will not tell you what
the egg is called.
Getting The Dragon Kings
Get a Kid to the Dragon stage or catch a Dragon
in the basement floors. Then, catch a Bomber and
evolve it into a Daedalus (they turn into the
upper forms at level 10). Fuse them together to
get Blith. Next, get a Daedalus and Vevil (Vevils
are found around the 90th basement floor). Fuse
them to get Yankash. The other Dragon King is
obtained by the same process, but use a Glacier
to fuse with the Daedalus or Vevil.
Get A Kid Egg
Find all three bells by defeating three special
Souvenirs. After you give them all to the old
man, go on a quest and return. Go find the old
man and he will give you a Kid egg.
Capture Rare Monsters
If you have an Ovaseed, just throw it at the
monster you want to catch. This is useful when
catching Souvenirs and Guardians.
Getting An Almost Invincible Monster
Catch an Alloyer and an Arachne. Make them both
transform into their upper forms, then fuse them.
You now need a Souvenir. Once you get one, fuse
that with your new monster (hopefully it is the
transformation of Arachne) to get a monster with
double speed. Next, you need a Barong. Fuse that
with the new monster (evolution of Arachne with
double speed) to get an evolution of Archne with
an ability that lets it gain extra experience.
You should now have a powerful monster. To make
it even more powerful, get extra Arachnes and
Alloyers and fuse them with it. Just make sure
you constantly have the evolution of Arachne.
After you get Gance, fuse your new monster with
it when ready. Your monster will be invincible
when it transforms into S-Gance. Get Mai-Soul and
fuse it S-Gance (if you do not mind losing it),
to become even stronger.
