champion concept: Kaphir

I am very fond of the assassin roles is league of legends especially Yasuo as he is a unique assassin who thrives in the top lane so my concept takes a lot of inspiration from him and more specifically his night bringer skin as you will notice later on. my champion concept is that of an assassin who can go in the top lane but is also more supportive through his use of cc and immobilisation as well as some sustain. His appearance is that of a hunched man with a cowl possibly from the shuriman deserts with spikes protruding out of his body seemingly randomly yet this is no corruption or magical being and could be considered like a distant relative to rammus or the vastayan due to his humanoid features. Firstly his passive which would give him that assassin feel through form of mobility attached to the rest of his basic abilities which goes on cool down after use per ability specifically on his Q and his W for the following reasons. His q is a quick ability similar to talon q in which the assassin will snap a spike from his body and stab his victim in a very swift motion ,this ability would stack up to 3 times before going on cool down and have a short window between use as well as applying a stack with a max of 6 and the spikes visually reside inside the victim whilst the stacks linger. His Q's form of mobility if his passive is off cool down would do the same yet could make him move behind the target after the Q's activation before going on cool down. His W works in the quite the same way but with different functions and animations whilst sticking with the 3 stacks until cool down his w though would have him make use of spikes he has prepared before hand and aren't just snapping off his back these spikes he stabs the victim once again but in a swift spinning motion like (like darius w) this ability ,upon activation causes the target to become immobilised lasting 1 second and adds a slow which percentage grows with every W spike used up to a max of 3. his W also adds a stack of a spike visually residing in a person making you able to stack up to 6 spikes in a person at once. The movement ability for this would be something that makes you sticky and able to keep pestering your target so maybe some sort of temporary movement speed and ability to go through units. Thirdly his E would be a detonation ability on the stacks of spikes inside a person upon activation this would make all the spikes burrow deeper into the target before siphoning blood which is given back as health as a percentage of damage dealt. This ability would be unable to have a movement option due to its longer cast time than other detonation abilities as he is recalling his spikes but taking a part of his enemy with them. his ultimate ability (which i am most proud of) will add to this supportive feel along with his W. His ultimate would relate in some way to his blood lust becoming stronger and would have a 1.5 second cast time of which after wards everyone standing behind him would become impaled on giant spikes which stick out of his back keeping them knocked up as long as the channel lasts for a maximum of 3 seconds and a maximum of 3 targets with each second applying a tick of missing health damage. I also believe that due to the nature of his abilities, like snapping off his spikes and using them that his abilities should cost health to cast but not his E as it is the ability he uses for sustain. EDIT: i just learnt recently that we are told about people that have failed ascension are called baccai and thought that this would suit his backstory really well due to his malformed appearance.
