Slaying Water Dragon grants experience to killer and nearby allies. After Water Dragon is slain, it will respawn at random.
- Restores 10% missing health and 10% missing mana every 18/12/6 seconds (based on stacks; +50% if they have Mark of the Elder Dragon).
According to Riot, the dragons auto attacks will be able to slow - mainly relevant if it's a potentially contested dragon, since the slow will limit your ability to disengage quickly. Some optimizations around getting it to attack an enemy for the slow situationally.
