Ulrezaj by Demolij

Ulrezaj is a very dangerous warrior to deal with, but doesn't work the same as other heroes. His damage output doesn't put him on the level of a bruiser and he doesn't provide enough cc to make him much of a tank, but he's a ball of health that does whatever the heck he wants to do, and his weird health system really emphasizes the chaos of his being. Your Trait makes it so that %health damage has almost literally no effect on you, making Giant Killer far less effective than it should be. It also naturally slows down enemies' damage as they kill you by granting armor for each portion of your health they kill, but this comes at the cost of greatly reduced effectiveness of healing on you, and if you get poked down and lose a segment then you have to wait a long time for it to come back, although not as long if out of combat. Although he seems like he could be OP, his lack of mobility engage damage and real utility makes him akin to a Cho without a Gall. Ulrezaj works poorly against poke but works amazing in dive comps and with lots of shields, and is a herd counter to percent damage.

Domination is a peculiar form of mounting. Being able to stealthily enter an ally can get you out of the base quicker, but it's also amazing at sneak attacks by letting you hop inside a hero off on their own or a sneaky invisible hero, then out you go, ready to wreak havoc. Ulrezaj can function as a main tank as long as he has an initiator on his side as well; you don't need a gapcloser if you can mount them as they dash into the fray anyways. He can also do well at backdooring, even though his raw damage isn't incredible he can still clear waves decently enough, and if he gets low he can hop inside an ally and speed away, all while stalling time for his segments to recharge. This comes at the cost of you being slower than everyone else's mounts, but it's worth the price of being able to drive a Catapult around like a toy car.

Chaotic Torrent is your only sustain and a nice source of poke, being your most reliable ranged attack, but is weak when it comes to waveclear. Landing it on 2-3 enemies is generally your best option, granting the most damage and shields. Feedback is a throwback to BW, and is a delayed form of hard cc that also deals high damage. It's functionally the opposite of Maiev's Umbral Bind, so if you cast it on an enemy they want to get away asap or be punched by a hard silence. Insanity is a very strong skill, instantly stunning enemies and dealing a bit of damage, and shutting down bad life choices. The range is really short though, meaning you need to get right up in the enemy's face to use it, which may not be too hard if you're Dominating an ally.

Confusion is incredibly potent against clumped enemies since it can cause them to deal a ton of damage and screw up their skillshots, and in the worst case it can force them to keep away from the afflicted ally. It is weak in some ways though, for example it's useless if the target is isolated from its allies in the middle of your team, and although the cooldown isn't very large unless the enemy has strong AoE abilities you're not getting the full value out of it, in which they can simply wait it out. The ability can have a very high impact but there's still counterplay involved so be smart about when you use it. Meanwhile Oblivion doesn't require a team to be useful, and can save your life or the lives of your allies. Using it during a teamfight is incredibly strong because it makes it impossible for enemies to really do anything, although unlike Isolation it doesn't silence the target and has a weaker effect. It has super long range but the effect falls off so use it whenever but don't whiff it!
