Ability Ideas
Toggled Ability Inflicts "Grievous Wounds" on self, but increases AD and AP Radioactivity
Skillshot Ability Projectile cannot move through terrain. When it touches terrain, it bounces off for a max of 3 times. Each time it touches terrain, it gains additional damage. Without touching terrain, it does damage only. When it touches terrain before impact, it inflicts a Slow as well as damage, and for each time it touches terrain its Slow percentage increases. Skillshot bouncing off targets
Targeted Ability Throws head at target, which sticks for a duration. During this time, his team gains reduced vision of the target (if enemy); also, [this Champion] can move its own body but does not have vision of it (other than with wards, ally vision, sight from the head, etc). His head can be attacked after a medium duration, and has [X] health; when it dies, it returns to [this Champion] and returns vision of his body as normal. If his head is on an ally, the head takes damage in place of the ally champion. Once his head is on a target, it gains different effects based on what target it is on. If it is on an enemy or neutral unit, it bites at it dealing damage over time until it returns to [this Champion]. If it is on an ally unit, it increases its Health Regen (Champion) or increases its damage (minion). Vision at the cost of self-vision
These are a few abilities I just thought of. They're not connected and they're rough drafts, but hopefully they gave you some ideas. If I think of any more and remember this topic, I'll share more with you all :)
