Sacrifice to Caiphon is on my short list of feats, along with Dual Pact (Infernal). The PC is going to have a "Suicide Black Deck" vibe going on, IYKWIMAITYD.
People in the group didn't give the Warlock more than a *ahem* cursory look when making their PCs, but I saw it as a vast improvement over the 3.5Ed version, and it quickly became the front runner for my PC concept.I hadn't really looked at Hidden Sniper for my Feylock because of the name of the feat (and because I haven't used her in many months, but that's another story entirely), but since it was pointed out here... man... that's almost too good!
As a Warlock, unless somehow prevented from moving (which becomes a lot more difficult for baddies to do once you can teleport a lot), you should always be triggering the concealment from Shadow Walk.
So when my Dwarf Starlock kept careening around the battlefield, one of the guys stated it was as if my PC knew capoiera...to which I said "Yah, mon! Hear de riddim of de steel drums!"
...before explaining that it was due to the Shadow Walking class feature. Now, having Hidden Sniper pointed out to me, the steel drums fueling my capoirist starbolt flinging dwarf will sound even louder (, mon)!
