Blood Spear is brilliant. Charge time that gives you X-Ray vision and operates like Windrunner's Shackleshot. Regardless of the rest of the kit, this ability is really strong.
I quite like Maledict, though. This is a nice bit of follow-up. The most dissonant thing about this kit is that it's not possible to follow-up on targets hit through a wall. A couple of things are happening in my mind as a designer: I want to see an ability that allows you to create a portal through a wall, so that you can effectively catch enemies hiding behind walls, while also giving your allies target access to them. Maledict looks like a portal--but it's fundamentally a finisher ability. There are a lot of ways that this ability could go, and it's fine as it is (and the character doesn't necessarily rely on attacking targets through a wall), but instead of making Maledict a follow-up, I think I would change its name and instead make it cut a portal through structures instead of dealing additional damage based on how much damage a target has recently taken.
Paralyzing Cask is an ability that I think needs more of an identity in the kit.
Death Ward is interesting, but mechanically I think that it is kind of weird that it incentivizes players to turn away from whatever they were looking at to shoot the death ward instead of targeting their enemies. I don't know how compelling of a gameplay device that actually is. I like that the ward counts as an obstruction. At the very least, I think there should be counterplay in making this destructible.
Capri Sun is a great touch.
