and what is Enchant revelation skill from berserker eagle

 

Enchant Revelation Skill means if the revelation skill you choose has Lv2 then you will get it.

E.g.

Savage Lv1: For 60 sec., P. Atk. + 10%, M. Atk. + 20%, Atk. Spd., + 10%, and Casting Spd. + 10%. P. Def. / M. Def. - 10%. Duration: 60 sec.

If you choose Enchant Revelation Skills from AP you'll get the same effect but without the P. Def. / M. Def. - 10%, i.e.:

Savage Lv2: For 60 sec., P. Atk. + 10%, M. Atk. + 20%, Atk. Spd., + 10%, and Casting Spd. + 10%. Duration: 60 sec.
