Thank you kindly, MaxQuest.
I think the Helmsman's Uniform is pretty insane. The only thing that offers that level of Deflection is of course the Cape of the Master Mystic, which means as a surrogate your cape slot is freed entirely - so you can use something that offers a high attribute boost (Mantle of the Excavator, Finreah's Grace, Shroud of Morning, etc.).
I'm not a big fan of % affliction chance per hit/crit weapons (as with both the Soulbound and non-Soulbound ones), I prefer guaranteed rolls on crit (We Toki, etc.) - but they still seem decent and pretty interesting, certainly not underpowered by any stretch. Someone should certainly think about slapping on all of Fulvano's stuff now.
The belt is good, but I can't see it surpassing the Looped Rope defensively. Still, with the hat too, I like the idea of some of these higher level attribute boni being concentrated on a single item - certainly frees up other slots without losing too much, particularly with the belt if you aren't too bothered about defensive boosts.
Good stuff, and thanks again!
