Medusa

Medusa the Gorgon is a ranged agility Hero. Highly item-dependant, she acts as a carry who can potentially strike down entire teams at once while protected by tank-like survivability. Split Shot allows her attacks to hit multiple targets, greatly increasing the potency of damage-granting items. Mystic Snake grants Medusa some presence in the lane and skirmishes, and its mana stealing refunds part of the cost to boot, making it an excellent farming and harrassing tool. Mana Shield protects her from the opening damage of teamfights, and if supplemented with items makes killing Medusa a fatally time-consuming process. Stone Gaze acts as a fantastic defensive mechanism against ganks and initiates alike, with crippling effects on all who dare face the Gorgon.

Tips

 * Mystic Snake should be maxed first as it is Medusa's only nuke and primary farming tool.
 * Try to aim Mystic Snakes to bounce off enemy creeps before hitting heroes to maximize their effects.
 * On a standard lane creep wave of 3 melees and 1 ranged, a level 4 Mystic Snake that bounces on the melees first will instantly kill the ranged creep on contact.
 * As more creeps are added to the waves, a few attacks with Split Shot active should be used before casting Mystic Snake to ensure lasthits.
 * Split Shot and Mana Shield are both highly item-dependant abilities. Consider spending pre-level 6 points in Attribute Bonus for a small but more tangible boost in power.
 * By activating Split Shot before you use Manta Style or Illusion rune, the illusions will gain the Split Shot ability which is a very good boost in terms of increasing your DPS.
 * Be wary about leaving Mana Shield active in the early to mid-game without a high manapool or some mana regen items. Heavy damage may leave you unable to cast Stone Gaze, which can turn the tides of a gank or teamfight when used correctly.
 * When pushing, activate Split Shot when attacking towers to whittle down an incoming creep wave.
 * Items built from Ultimate Orb and Perseverance are good for Medusa, such as Linken's Sphere and Manta Style. The bonus stats and regen make Medusa very tanky with Mana Shield active.
