Still tweaking my character before my entrance.
Just picked up a level 1 Daily called "Decree of Khirad" that attacks vs. Will in an ally-friendly blast 3. I shift around my targets and, on hit, force them to attack creatures of my choice... which can trigger defender mark effects! Granted, marked enemies will take -2 for not attacking the paladin, but they'll also eat the radiant damage! And if they miss, they take 1d6 + mods psychic damage from me.
Sadly, there is almost zero magic item and class feat support for Hexblades. Most of the warlock magic implements have effects based on the warlock curse (which I don't have). Same with the feats.
Hopefully they'll increase the available options at some point.
