How would you do it different? What "defines" a wraith in 4e as different than other monsters incorporeal undead? I genuinely interested in how others would design it.
A wraith (Level 5 Lurker) weakens opponents on a hit (vs. Ref...so it's likely to hit), is insubstantial (meaning 1/2 damage), and it regenerates. And with phasing and Shadow Glide, there are no OAs to help out. So it's often the case that at least one person attacking the wraith is
completely ineffective after the first round.
Are you saying that what defines a wraith is that one attacker is always ineffective?
I'm afraid that's not what I think of when I think "wraith". I think of "
a restless apparition [that] lurks in the shadows, thirsting for souls." ...just like the designers do, apparently.
The "weakened" condition sounds good, IMO. It's just when it's combined with all the rest that there's a problem. IIWaD (If I Were a Designer), I'd remove the regeneration, change insubstantial so that all damage is full, and change the hps of the wraith to bring it back in line with other level 5 lurkers. (After all, what to hps represent, anyway? In the wraith's case, they represent how hard it is to damage something that's insubstantial.)
