Official update released April 21, 2020. Key highlights: New Hero: Popol and Kupa , Icefield Companions Hero Adjustments Battlefield Adjustments: Battlefield, Equipment, Spells New Functions & Events System Adjustments Bug Fixes.

All Documented Modifications (6)
Designer Note
The strongest duo from the northern icefield.
Popol always fights side by side with his best partner, Kupa. Popol takes good care of Kupa. If Kupa hasn't taken any damage in a few seconds, it will regen certain percentage of the max HP every second. When Kupa is down, Popol can pray to summon it back to the battlefield. After consecutive attacks by Kupa on an enemy, the next attack of Popol will be enhanced. Kupa receives Popol's attributes, as well as his equipment effects (except those of the active, jungling and roaming equipment items)
Popol throws a spear at the target that deals physical damage, and orders Kupa to bite the target, dealing damage and following up with attacks. Alpha Wolf Form: Kupa strikes ferociously, stunning the target with rapid bites, dealing large amount of damage.
Popol summons Kupa to protect him, gaining a shield, dealing damage to the nearby enemies and slowing them. Kupa will assist Popol in attacking nearby enemies. Alpha Wolf Form: Kupa darts back to protect its master and knocks nearby enemies airborne.
Popol sets a trap at the target location, which will detonate after a short delay when an enemy is near, immobilizing the enemy and creating a freezing field that slows enemies within the area of effect. Popol can store multiple traps.
Popol and Kupa both become enraged for a period of time. Popol and Kupa gain attack speed and movement speed. Kupa enters Alpha Wolf Form, restoring full HP, increasing its max HP and physical attack, and enhancing its other skills.

Adjustments applied to Fist Break, Fist Crack.

All Documented Modifications (3)

Kaja
Kaja hero Nerf

Adjustments applied to Lightning Bomb, Divine Judgement.

All Documented Modifications (3)
Designer Note
Since we've improved the "Suppressed" effect associated with Kaja's ultimate, he provides better control now. We decided to lower the damage of his ultimate.

Total Magic Power bonus increased from 80% to 120%.

Carmilla
Carmilla hero Buff

Adjustments applied to Crimson Flower.

All Documented Modifications (2)
Designer Note
Being able to constantly harass her opponent with a high movement speed makes Carmilla hard to deal with. After careful consideration, we decided to remove the movement speed boost provided by her skill 1, Crimson Flower, and improve her durability in return.
Removed the Movement SPD Boost. HP restored on each hit increased from 50-125 to 60-150.
Role: Support, Tank
Tier: A
Patch History: 13 Updates
Ling
Ling hero Nerf

Adjustments applied to Cloud Walker, Defiant Sword.

All Documented Modifications (3)
Designer Note
We believe it makes more sense to have Ling relatively weaker in the early game, given his dominance in the late game. From there, we decided to lower the crit chance on his passive once more, so that he farms reasonably slower.

battlefield Adjusted

Necklace of Durance values and gameplay tuning.

All Documented Modifications (1)
Designer Note
We've fixed the issue that healing reduction effect doesn't work against skill lifesteal and magic lifesteal. To avoid some of the equipment items with this effect getting overly strong, we decided make adjustments in advance.
Sanctum Island & Competitive Map Scope Impacts neutral creep pacing, lane economy & objective control.

Flameshot
Flameshot battle spell Adjusted

Flameshot values and gameplay tuning.

All Documented Modifications (1)
Designer Note
Flameshot seems to be too well rounded in current meta, especially some melee, heroes can take advantage of the knock back effect to finish their attack combos. Thus, we adjusted the close range damage and long range slow, so that players will have to make a choice between damage and control.
Cooldown: 50s
