Flow is way better!

If you went scarab drow, I think space would be really good, you could easily maintain all preps. However I think that another underrated aspect to the Maran, that I severely underrated while playing Drissa, is how easy it is to stay very low weight while carrying a ton of Dunya ingredients/limited preps. No need to carry flight/protection/lots of extra weapons is pretty good. I would vaguely worry about weight on that drow.

Swift strike is incredible, the more I look back on that character the more I think that swiftstrike+swiftblade is what made it exceptional in combat even compared to some other examples of the same/similar build on drow.
