I'm fond of using Wraith Crowns at certain points in the game - against many troops, even summoned ones, it gives twice the benefit of luck (3/4 attacks negated vice 1/2). In addition, the initial mini-swarm of undead tends to slow down flyers (aquatic and terrestial) long enough for some buffs to be successfully cast.

I've used the robe of shadows less often, because there's usually a better suit of armor for most combat chassis's; however I have used it a few times on commanders with high innate PD and water magic - since they can self-haste, they don't need the jade armor.
