Lady Vashj (Sea Witch Concept) by Lehmyare

When dealt damage while at/under 25% health, summon a Myrmidon to protect you. When summoned, the Myrmidon will stun the closest enemy hero near you for 2 seconds, then attack the last enemy attacked you, unless you're further than basic attack range from the target. Myrmidons will protect you until you are above 75% health or are slain. While they're protecting you, 25% of the damage you take is transferred to the Myrmidon. Myrmidons have 514.12 (+10% per level) health and deal 65 (+4% per level) damage per second. Only 1 Myrmidon can be alive at once and can be only summoned once every 30 seconds.

[Unending Devotion] Myrmidon dies before your healthy, reduce cooldown.
[Increased Detail] Increased maximum number of Myrmidons on the battlefield, and reduced requirement.
[Watery Surprise] Myrmidons leave a puddle upon dying, and reduce cooldown of Dive.
[For the Matron] Prevent fatal damage and heal, if Myrmidon is alive while taking fatal damage.

Mana: 15 per Basic Attack | Cooldown: 1.5 seconds | Toggle

While active, basic attacks deal 121 (+12% per level) damage, slow enemies for 10%, stacking up to 40%, costs 15 mana per basic attack, and slow lingers for 1 second after not being hit by Frost Arrows.

If the enemy is wet (not in puddle), Frost Arrows root them for 0.5 seconds.

If the enemy is in a puddle, all enemies in the puddle are rooted for 1.5 seconds, the puddle is removed, and the enemies are no longer considered wet.

[Lingering Frost] Hit enemy heroes to increase duration of slow and root.
[Dynamic Frost] Increase basic attack range while active.
[Calming Cold] Basic attacks reduce cooldowns while active.
[Siphoning Chill] Frost Arrows heal you for half the damage.

Mana: 50 | Cooldown: 15 seconds

Shoot a bolt of lightning that deals 83 (+4% per level) damage to non-hero enemies along the path, but stop on the first enemy hero it hits. If it hits a hero, Shock Blast explodes doing 25% damage to nearby enemies (explosion doesn't benefit from the wet debuff or puddles).

If the enemy is wet (not in puddle), Shock Blast deals 200% more damage and removes the wet effect.

If the enemy is in a puddle, all enemies in the puddle receive 150% of Shock Blast's damage.

[Rolling Thunder] Increase damage every time a enemy hero is hit.
[Piercing Sparks] Shock Blast pierces the first enemy hero it hits.
[Emanating Thunder] Shock Blast causes an expanding nova instead of a bolt.
[Cascading Energy] Every time Shock blast hits an enemy, refresh duration, but cost extra mana.

Mana: 20 | Cooldown: 12 seconds | 2 Charges

[Engulfing Waters] Debuff enemies to increase duration of debuff.
[Familiar Waters] Using Dive reduces cooldown, but costs mana.
[Growing Tide] The puddle grows in size over its duration.
[Cold Water] Isolated Storm's puddle slows and reduces armour.

Cooldown: 15 seconds

[Thunderous Storm] Selected Area's ability is now global.

Mana: 50 | Cooldown: 80 seconds

Become Invulnerable and summon 4 Tainted Water Elementals, each having 357 (+15% per level) health. You are invulnerable until all 4 water elementals are killed. When invulnerable you are unable to move, but for every second that you're invulnerable, your basic abilities deal 10% more damage, this effect stacks up to 100% additional damage. When the elementals are slain, retain the bonus damage for 10 seconds.

Can be canceled at any time.
