... drop locations in Solsthiem, please.

Been there once to collect schematics for Sorine, but dont want venture to deep in the dlc till I feel I am ready. Any good drop locations for em, most notable?

Smash an grab type situation, in an out. Level 25 invis castin assasin with level 80 sneak skills, will be my guy.

Thanks.

P.S. High drop count.

I believe it is called exploration, buying them or making your own. They seem to appear randomly to me.
