Nonweapon items that add damage to your attacks.

[pastorman1974]

I just got the Quiver of Venom and it adds poison damage to ranged attacks. I was wondering if there were any other items that added damage to attacks. I'm not talking about socketed gems or the like, but other non weapon items that give bonus damage.

Deadly (https://ddowiki.com/page/Deadly), Seeker (https://ddowiki.com/page/Seeker), and Backstabbing (https://ddowiki.com/page/Backstabbing) / Deception (https://ddowiki.com/page/Category:Deception_items) bonuses are available from gear. I'm blanking on other imbue-like effects similar to Quiver of Poison, but there's probably some. You should also look for gear with Melee / Ranged Power and Doublestrike / Doubleshot bonuses - depending on whether you're a melee or ranged toon, obviously.

adding:

the memory lapse helm that adds poison damage
another quiver adds flaming, I forget which one
old red dragonscale added flaming 'eternal fire'
some older stuff out-of-date out of Amrath (edit: mentioned above)
jidz for monks and other unarmed strike boosters, too many

rune arms...

frozen tunic but that is technically not damage

Straight up non-weapons that add damage to anything:
Dragon Masque (FoTP)
Echo of Icon of Ravenloft (Baba)
Shadow Killer Thunder-Forged Armor

Melee only:
Spiked Gauntlets (Crystal Cove)
Charged Gauntlets (Chrono) - vorp only
Crazy New Charged Gauntlets (KT) - vorp only

Spells - maybe outside scope:
Resonation (DoJ)
Lantern Ring (Haunted Halls)

nice additions
Crystal cove also has the trinket with lightning hit
Those Killing time gloves are a play off of the Pendant of the Stormreaver, so we can add that too
Sanctified gages add light damage
the Trace of Madness items can be upgraded for solipsism but that is a Sap
effect, not damage

Monks specifically have the Jidz-Tet'ka (which can give a damage die) and Perfect Pinacle (which, besides Reinforced Fist, which is a half die, can add electric and bleeding damage in storm stance). While mentioned previously, obviously, the Quiver of Poison and Purifying Quiver are the most direct examples I can think of, along with a few like the Dragon Masque that I haven't personally used. There are others, though I don't think that you're looking for a list of things with deadly or sneak attack as those are kind of generic compared to the quivers.
