Black Dog Style Death Attack?

[tuesdayscoming]

So levels in the Black Dog class from Dragonmarked give a Death Attack whose DC explicitly stacks with levels in Assassin. Thus, a level 10 assassin, level 5 black dog with 10 int would have a death attack DC of 25.

Anyone know of any other class that increases death attack DCs in this way?

Telflammar Shadowlord from Unapproachable East

Black Flame Zealot from Complete Divine... or was it Complete Champion?

Marchosias, the King of Killers is a Vestige that grants a Death Attack, and stacks some fraction (I'm AFB and can't check; probably 1/2 or 1/3) of your EBL with Assassin and the like. Unfortunately, as a 7th level Vestige, Marchosias requires a minimum of 13th level Soul Binding (plus the Improved Binding feat), which is going to be hard to fit into a build with 5 levels of Black Dog and 10 levels of Assassin, heh. In Gestalt you could maybe do it, though most would probably take pause from having both sides improve the DC.

The DC for any of the binders abilities is 10 + 1/2 EBL + cha modifier. And it states nowhere that that the DA stacks with DA gained from any other classes, while Black Flame Zealot and Telflammar Shadowlord have it explicitly stated in their DA entry.

Uuuh, what I actually came back for was this thread I stumbled upon when I tried to build a optimized death attacker. http://www.giantitp.com/forums/showthread.php?p=9887632

Tellflamar Shadow lord also has this clause IIRC

Here is (http://www.giantitp.com/forums/showthread.php?p=9887632#post9887632)a list of death attack classes I put together a while back. Nearly all of them stack with assassin if I recall. Telflammar Shadowlord is my favorite of the bunch besides Black Dog, though I'm currently playing a Deathstalker of Bhaal in a campaign.
