If I read the DDO Wiki correctly, none of the in-game vendors sell the Topaz of Deathblock (ML12) augment. I'm looking for one, but have never seen one on the AH. How much would one of these set me back?
I'm planning to stick this in the Nightsinger's Mantle on a Drow Enlightened Spirit Aura/Burst Fey Warlock tank build, along with a +7 Diamond of Spellcraft (if I can find one). Is that a decent idea, or would I just be better off waiting until Mabar to grab a Cloak of Shadows as her Deathblock item?
I'm still trying to learn what's best to stick into augment slots. This game has changed so much since the time I was super active back in 2010-2012!
