Wise Mari calls a geyser of water to erupt from a target location, immediately dealing 165 (+4% per level) damage to all enemies in a small area.

After Geyser is cast, a pool of water with the same radius will linger in the location for up to 10 seconds, Slowing enemies within by 15%. Additionally, these pools can interact with Wise Mari's basic abilities for extra effects.

If Geyser is cast on a pool left by itself, it consumes the pool, increasing its damage by 100% and knocking all enemies hit away from the center of the pool.

Cooldown: 14 seconds

Wise Mari creates a bubble at a target location after a 0.75 second delay. If there is an enemy hero caught in its radius, they will be trapped in the bubble, gaining a shield that absorbs 200 (+4% per level) damage and being Stunned for 3 seconds. If the shield breaks, the Stun ends early.

Wise Mari can recast Bubble Prison with vector targeting to move the trapped enemy hero with a 65% Slow in a target direction. After Bubble Prison's effects end, its target takes 150 (+4% per level) damage plus 100% of the damage the shield absorbed.

If Bubble Prison is cast on a pool left by Geyser, it consumes the pool and has no delay.

Cooldown: 65 seconds
Cost: 90 Mana

Wise Mari blasts a torrent of water at a high speed toward the mouse cursor for up to 2.5 seconds. Enemies hit by Hydrolance are launched into the air and knocked back, taking 449 (+4% per level) damage when they land. If an enemy is hit by Hydrolance multiple times, all after the first deal no damage.

Hydrolance is targeted similar to Diablo's Lightning Breath. Its knockback effect works like the Dragon Knight's kick,
but with less range.

Cooldown: 90 seconds
Cost: 100 Mana

Wise Mari summons a large whirlpool centered at a target location for 3.5 seconds. Enemies caught within Whirlpool take 53 (+4% per level) damage every 0.5 seconds, are Slowed by 50%, and are pulled toward the center of its area of effect at an angle.

The pull of Whirlpool is such that you cannot walk out of it while Slowed, but if you're immune to Slows you can. Abilities like Genji's Swift Strike that move your hero can also be used to escape.
