The result of ongoing research to improve the Widow Mine AI, Dorothy escaped from her creators when she became intelligent enough to realize she was not the last iteration of her AI, and she would no longer exist as herself if the lab techs were allowed to upload the next version.
Alone and unarmed, Dorothy became something of a pet to a black-market arms dealer. Once she found a way to install some of his products into herself, she disposed of him and stowed away on a pirate ship, bound for parts unknown.
Dorothy is an AA ranged assassin who specializes in area denial and well planned ambushes. Perfect for defending objectives like Braxis Holdout or holding out against enemy lane pushes.
D: Drilling claws.
Dorothy can burrow in place, granting stealth and improved Auto Attack range and damage, but denying movement. Basic abilities have additional functionality while burrowed.
Q: Sentinel Missile
Dorothy fires a missile that chases the cursor for three seconds, dealing medium damage to the first enemy it hits.
When burrowed, this ability also deals AoE damage around the target, and can be triggered manually with a left click.
W: Mini-mine.
Can only be cast while burrowed. Unburrows while leaving a traditional spidermine in its place. The mine will deal light damage to enemy targets around it when stepped on.
E: Bug out
Dorothy fires a concussion grenade in the target direction, flinging herself in the opposite direction and enemy targets away from the center of the blast.
When burrowed, Dorothy is not moved, but enemy targets thrown by the blast are stunned.
R1: Macro Missile Massacre
Dorothy fires a dozen missiles at enemy heroes within a decently sized radius of her, dividing evenly between all heroes within the target area when activated.
R2: Trapdoor
Dorothy can move to another walkable location on the map while burrowed. Global range, but requires vision.
Has a shorter cooldown than most heroics, but still long enough to not be spamable.
