Why do you want to Multi-class?

[JeffreyGator]

I multiclass because I can.

And if I fail with MC build? Whats the difference between grinding 1-20 levels or grinding Shroud? And on top of that, there is reincarnate/respec.

Leveling is more fun than rerunning shroud and doesn't take 12 people of whom at least half a dozen need to kno0w what they are doing?
