Pyke's self-inflicting harm abilities speculation

Anticipating something like the below for Pyke:

• Some % of damage received inflicted is reflected on the dealer (As with thornmail)
• All attacks inflict grievous wounds.
• If someone attacks a champion Pyke has used one of his abilities on, they are rooted and receive damage.
• For each ability used, enemy champions affected by some Pyke ability inflicts X damage for the next 5 seconds.
