Davy Bones is sailing the low seas

This is the second champ i came up with and i had a few sketches but sadly they aren't on a computer and i lost them but I might still have a picture somewhere im still looking. if any of these ideas or other ideas sound familiar it is probably because my brother stole them and wrote them down first

Once the infamous Captain Bonebeard of the the pirate ship the Boneyard , Davy Bones was wrecked by krakons swimming together in an unusually large group.Now a reborn ghoul, he is seeking a treasure he buried long ago and is said to return a ghost to what he used to be... [zombie-nunu-bummed]

Q:Sinking Slash: cost:(20 mana) empowers next basic attack and acts like a tiamat but if it kills the target it pulls hit enemies in and stuns if more than one was pulled. range of splash is equal to range of cleave. [also slows]

W:Bone Throw: cost:(25/30/35/40/50 hp) sacrifices some health to throw a skill shot bone that bounces in a large area 6 times if landed. if it kills health is refunded for one kill and increases the more enemies it kills in on throw. if no kill the bone lands in a random area 150 units from last target struck and acts as small terrain. [range on throw and bounce tbd]

E:Disintegrate: cost:(50/50/75/75/100) turns to dust and and reforms at target location in a large range. travel time: .1 sec per 200 units (counts as blink)

R:Pirates Revenge: (cost:100 mana or free if two kills in last 15/30/60 sec) giant pirate ship erupts out of the ground Davy rides it. range = nami ult enemies hit are knocked up.recast to hop off. when aboard your other abilities become cannonballs (1 use each per ship).

P:revenge of the drowned ones: Anyone under 10% health nearby when he dies is dragged in and executed ( 3 min cd) [sg-kiko]

Cooldowns are tbd

For a skin i was thinking either graybeard plus chromas. pre-wreck Davy Bones would work too
