Death 9 bless, Death Weapons, is melee only... but increased affliction chance works for missiles. Wardens with 250% affliction chance at Crossbow range?
Also, it seems there are quite a few LA nations that can't use their native gem income. Ulm gets 2 Death, 1 Astral and 1 Nature gem, but can only get N1 and D1, and even those only through randoms.
