Best class to solo glasth instance

I'm playing Ragnarok latam, I already have an sura lvl150 that can solo glasth relatively easy.

Now I would like to create a new class to solo it too, just to earn more zenys, what is the easiest class to do it?

With easiest I mean, minimal investment and early lvl.

I started making an assassin to farm, but I'm not sure if it can handle glasth.

Thanks in advance.
