Sage Elemental Change?

[Leviathan123]

I just made a Sage and talked to the Special Skills person and he wants me to pick an element for Elemental Change? What is this and which one should I pick? O.o

Permanently changes the element of the target monster. Of the 4 elements Fire, Water, Earth, and Wind, your sage may only learn to change to one of of them. When the skill is cast, it will use one Elemental Converter of the element you've chosen. This skill does not affect boss monsters or players. The chance of success is based on your level of that elemental endow, as well as your DEX, INT, and Job level. With medium to high INT/DEX and high level Endows, you should have close to 100% success rates.

Choose wisely though, you can only have one elemental change. If you plan on using Waterball in the later stage when you get yourself a Drake weapon, then fire. 

Otherwise it is up to you which spell you love most.

Since it's only use is in PvM, pick one that best benefits you and other players, like party members. Fire works well since many attacks are water type (Storm Gust, Suiken FO's, Water Ball) and Wind works nicely for Heaven's Drive spam.
To make the catalysts, you need their respective ingredients and blank scrolls, which you can buy from an NPC in Yuno, directly north of your spawn point.
I wish it worked in PvP, but oh well, I don't think anything will be done about that.
