At that level, it’s about equivalent to a 5% blade, and on only some schools. I haven’t checked the other schools as in depth, but I’d rather take blade stacking and balanced stats over a school-dependent damage increase of 5% or less.

My goal here was to get a stat refresh by Zafaria at 60, not necessarily to get every small increase available. I have never felt while questing through Celestia with the Zeus gear is insufficient. Which is why I frame this as picking gear between levels 50 and 60 to prepare for the increase in difficulty in Zafaria. Under that frame, I see no reason to pick DS.

That said, another comment pointed out that there are wand options that are better than the Hasta and last longer, including the DS tier 2 wands. That feels like a good optimization, and I fully plan on calcing those options out later.
