Sonic The Hedgehog

Sonic's the name and speed is his game! Sonic is a survivor who's all about quick movements and close range single target damage. Sonic's higher than normal movement speed and many movement skills let him jump from enemy to enemy when in combat, or explore the map quickly when looting. Though he's frail, his quick movements and invincibility frames let him avoid danger while he does major damage to nearby enemies.


Passive - Momentum

Build up speed by running down hill to move up to 100% faster. Lose speed by running up hill to move up to 33% slower.

Primary - Melee

Melee nearby enemies dealing 200% damage. Every 5th hit deals 600% damage. Targeting an enemy in the distance will use the Homing Attack, dealing 600% damage.

5-hit melee combo. Looking at an enemy that's out of melee range but within a certain distance will use the homing attack, quickly bringing you to the enemy and dealing damage on contact. The speed and max distance of the homing attack scales with movement speed. While approaching an enemy with the homing attack, you get 100 armor.

Secondary - Sonic Boom

Fire shockwaves dealing 2x160% damage.

Fire 2 small projectiles straight forward that create a small explosion on impact. Start with 3 charges by default. All charges come back at once after a 5 second cooldown.

Utility - Boost

Spend boost meter to move 35% faster than normal. If health is near full, move 65% faster instead. If airborne, do a short mid-air dash.

While boosting, your movement speed is increased by 35% and you are given 50 armor. If your health is above 90%, you will power boost, increasing speed by 65%. Activating boost gives invincibility for a brief moment. Boosting will drain your boost meter. If the boost meter runs out, you will be unable to boost again until the meter is recharged. The boost meter recharges overtime when not boosting. % based cooldown reduction, such as Alien Head or Brainstalks, will reduce the speed at which the boost meter is drained and increase the speed it comes back. Flat cooldown reduction, such as Purity, will increase the max capacity of the boost meter. By default, you can use boost as a mid-air dash once before having to touch the ground. Any additional utility stocks, such as those from Hardlight Afterburner, will let you use the mid-air dash more times before having to touch the ground.

Special - Grand Slam

Homing. Dash forward into an enemy to attack with 140% damage repeatedly before unleashing a powerful attack from above dealing 2200% damage.

This attack will home in on the enemy closest to the crosshair, similar to the homing attack. The amount of repeated weak hits you will do is 5 by default, but increases with attack speed. After landing the initial dash attack, you will have invincibility for the rest of the move's duration. 12 second cooldown.
