I made this guy to be a Tank/Little Support:

Bereon, the Altruistic Fighter

Passive: Avenger Parrot

Bereon has a parrot which accompanies him. If Bereon dies, his parrot will attack the nearest champion in sight, dealing 3/4/5% of the champion's maximum health. If there are no nearby champions, Bereon's reviving time is reduced in 4/6/8 seconds.

Q: Accurate punchs (one-click ability)

Bereon punches the target, dealing physical damage and stunning the target for 0.5 seconds. In the next 2 seconds, Bereon can punch another target, but without stunning. After this second punch, and if Bereon has 75% of his maximum health at most, he can punch again, applying the 0.5 stun this time.

W: Provocation (one-click ability)

Bereon taunts the enemy target for 0'5/1/1'572/2'5 seconds. If Bereon uses this ability when he has 25% of his maximum health at most, the taunt lasts 1 more second.

E: Life Guard

Bereon enters a protective stance for 2/2.5/3/3.5/4 seconds, increasing his armor in 11/22/33/44/55 and his Health Regeneration in 10/20/30/40/50 per 5 seconds for the duration.

R: Sacrifice

Bereon sacrifices a 50/60/70% of his current health to heal every allied champion in a range for a 25/40/55% of their maximum health. In addition, it puts a shield on these allies which absorbs little damage for 2 seconds. Neither the healing nor the shield affect Bereon.
