An Idea for thamaturge second job(voidsent pet class)

[shinros]

I have been talking with some friends and the FC I am currently in about what should be thaumaturges second job. Since Yoshi said he wants each class to have two job options.

Since people normally think of necromancer for a second job that is not possible since that play style is taken for summoner we could have a burst pet class.

Now here is my idea we know that thaumaturgy is the dark arts and black magic is connected to the very void itself so how about a class that is centered around diabolos? I mean he is most likely going to be a voidsent if he is added to the game instead of a primal considering he is a demon and all demons come from the void in this game. So like the summoner they can use an enslaved essence of diablos(since we don't want the actual guy flying around).

Here is his wiki page.

He could use void fire, void blizzard and void thunder like the other voidsent and have a skill where the enemy takes extra damage from elemental attacks for X seconds. Anyway I am just throwing around ideas what do you lot think? Or they could use some of his XI skills they would really suit a thaumaturge.
