To bring out a monsters best skills you should...

1. Capture 2 monsters that have never been breed,and have the skills you want. Preferably a male and female which you will breed when they get the right skills.

2. Bring those monsters with you on your journy to a travelers gate with stronger monsters in it. Also bring lots of lovewaters, meat treats, and anything else that's usefull(like warpwings and warpstaffs.)

3. Prolong battles with 2 to 3 monsters in it and give meat treats to the monsters you want to level up and learn skills.

4. When the monsters get the skills you want them to learn (you might have to get them to their max level)breed them.You'll have to get the new monster up to the right level so it'll have the skills you wanted.

5. Remember,a monster can't learn a skill its parents did not. If 2 monsters are breed and only learn heal, than the baby can only learn heal.

You must breed together a Servant and Great Drak, with Servant being the pedigree.
