Gloo
Gloo hero Adjusted

Gloo, a mischievous troublemaker, is composed of mysterious creatures that merge together.

All Documented Modifications (4)
Designer Note
Gloo, a mischievous troublemaker, is composed of mysterious creatures that merge together.
Enemies gain a stack of Sticky each time they're hit by Gloo's skills, decreasing their Movement Speed. Stacks up to 5. Each stack of Sticky on an enemy reduces their damage dealt to Gloo.
Gloo reaches out and slams the ground, damaging the enemy and leaving behind a "Goo", and after 3s it explodes to damage and immobilize nearby enemies. Gloo can also make the Goo explode immediately by touching it.
Gloo stretches forth to deal damage and immobilize enemies in its path. If this skill hits a "Goo", the Gloo charges over to it, dragging enemies in its path to the destination.

Argus
Argus hero Buff

Adjustments applied to Warmonger, Demonic Grip.

All Documented Modifications (3)
Designer Note
Having listened to your opinions, we've focused on improving the experience of using his enhanced Basic Attacks, optimizing how they feel to use and the damage they deal. In the interests of balance, we'll be reducing his Physical Attack somewhat.
First Two Basic Attacks' Damage: 85% Physical Attack → 100% Physical Attack Third Basic Attack's Damage: 100% Physical Attack → 110% Physical Attack Increased the Attack Speed of enhanced Basic Attacks. Slightly increased the Energy gained when dealing damage. Slightly reduced the Energy gained per second. If an enhanced Basic Attack kills an enemy, the attack will no longer continue.
Slightly widened skill range. Slightly reduced stun duration.
Role: Fighter
Tier: D

Beatrix
Beatrix hero Nerf

Balance adjustments applied to Beatrix.

All Documented Modifications (1)
We realized that playing as Beatrix was a little extreme; in the early game she could exert a lot of pressure upon enemies, creating a snowball effect as she got stronger and stronger. And if this early-game opportunity was missed out on (as it was in most cases), it'd be difficult for her to be of use in teamfights. With this round of changes, we hope to nerf her early-game performance (readjusting some of the previous nerfs) and buff her in the late-game as appropriate.
Role: Marksman
Tier: C
Patch History: 17 Updates
Yve
Yve hero Nerf

Adjustments applied to Void Blast, Void Crystal, Real World Manipulation.

All Documented Modifications (4)
Designer Note
As a core Mage, Yve excels in her damage output. Nonetheless, with no control effects or defensive measures, she appeared to be a little helpless when under threat from the enemy. To deal with this, we've improved her survivability when casting her Ultimate as well as her ability to shut the enemy down; and to keep things balanced, her damage has been nerfed accordingly.
Damage per Hit: 200-375 +90% Magic Power → 180-330 +80% Magic Power
Each Hit's Base Damage: 110-210 → 90-165
Tap Damage: 400-550 +120% Magic Power → 360-490 +110% Magic Power Base Slide Damage: 130-210 → 105-165 The former slow effect inflicted when touching the edge of her starfield has been replaced with 0.5s immobilization instead. New Effect: Yve now gains a large Shield upon casting her Ultimate (500-900 +150% Magic Power, an amount that scales with her Passive stacks to a maximum of 150%). This Shield lasts for 3 seconds after her Ultimate ends, then disappears. We've greatly increased the response speed when attacking with her Ultimate. Slightly adjusted the perspective when using her Ultimate, to improve accuracy when using her starfield. Fixed an issue where the "Hero Lock Mode" could prevent you from sliding when using the Ultimate. Improved the smoothness of movement following the Ultimate, so that you can now move as usual once it ends, no matter when you start moving the joystick.

Natalia
Natalia hero Buff

Adjustments applied to Assassin Instinct.

All Documented Modifications (2)
Designer Note
Having taken everyone's suggestions into consideration, we've decided to keep all of Natalia's characteristics intact; however, we've changed how you silence enemies to delay silencing effects. We've also made her mid-to-late game damage dealing and survivability stronger. We hope this all serves to strengthen her overall performance a little, while still leaving room for enemies to deal with her.
Enhanced Basic Attacks now mark targets. Only when the mark is triggered by the next enhanced Basic Attack will the target be silenced. Silence Duration: 0.6s → 1s Base Damage of enhanced Basic Attacks: 350 → 250 Total Physical Attack Bonus for enhanced Basic Attacks: 90% → 120%
