"Wraithblade" ?

3) I don't know what 3) means as I am not aware of any encounter-based sneak damage limitation. But at least it's harmless (doesn't need errata, because it doesn't do anything)

Sneak of Shadows....Nuff said.

I disagree, although not strenuously.

If you have combat advantage already, you automatically can already do sneak attack damage. With your interpretation I think the only way the weapon has an effect would be on those very rare circumstances that you attack (and get sneak attack damage), spend an action point, attack again and get a critical. I guess you're welcome to hand out such an item if you like, but that seems woefully underpowered to me.

While not a big deal for rogues, this interpretation is a big deal for Sneak of Shadows users. Non-rogues who MC into Daggermaster could go from one SA per encounter to roughly one in every seven attack rolls, regardless of whether or not they have surprise or a teammate to flank. That's pretty nifty, especially for Rangers or Tempest Fighters. Luck into a couple of crits with Rain of Blows or Blade Cascade and the Wraithblade is all kinds of awesome

Tasty cheese then, melty and goey all over your character sheet

Hello kinda new both to 5e and DMing . One of my players wants to create a Wraithblade PC . Not the 5e rogue archetype , but rather a recreation of the DDO Rogue / Wizard multiclass . A magic wielding assassin who specialises in briefly assuming undead form via Shroud , which , alas , don`t seem to exist in 5e ...Ironically , Libris Mortis has a Ghostform spell that would work , if it weren`t 8th level...
Thus far , the closest that we`ve been able to come is a Rogue 7 / Wizard 13 . Take Rogue at 1st level for skills , equipment , sneak attack and Expertise . Later the Assassin path. For the Wizard side , Necromancy Tradition , Disguise Self , Alter Self , and spells that duplicate as much as possible the wraith abilities. Suggestions?
