Patch 1.8.66B

Season 32 Released March 28, 2024

Patch 1.8.66B - Competitive Balance Adjustments

Official update released March 28, 2024. Key highlights: Hero Adjustments.

1 Buffs
1 Nerfs
3 Adjusted
5 Balance Adjustments
Masha
Masha hero Adjusted

Adjustments applied to Ancient Strength, Wild Power, Howl Shock, Thunderclap.

All Documented Modifications (5)
Designer Note
In the last Patch, we adjusted Masha's playstyle to make her a bit more difficult to play, which has resulted in her not being as strong as expected at the moment. We've fixed several of Masha's shortcomings, including being easily kited while her normal attacks don't hit, being vulnerable to continuous control that prevents her skills from being cast, and having difficulty building up her Energy before late game team fights due to long skill cooldowns and high HP Costs. We hope that the adjusted Masha can shine in the Jungle position. Corrosion Scythe, Sea Halberd, and Blade of Despair are recommended for early and mid game, along with the Ultimate reset from the Passive, she can kill the enemy over the Turret. Antique Cuirass and Athena's Shield are recommended for late game to improve her survivability.
New: When depleted, each HP bar blocks one instance of damage and removes CC effects for Masha.
HP Cost: 24% → 24%-16%
HP Cost: 24% → 24%-16% Cooldown: 15-10s → 8-6s
HP Cost: 34% → 34%-24%
Role: Fighter, Tank
Tier: B
Patch History: 21 Updates
Miya
Miya hero Buff

Increased her Skill 2's arrow damage, but the total damage remains the same.

All Documented Modifications (2)
Designer Note
Increased her Skill 2's arrow damage, but the total damage remains the same.
Arrow Damage: 30-80 +15% Total Physical Attack → 40-105 +20% Total Physical Attack Number of Arrows: 8 → 6
Role: Marksman
Tier: B
Patch History: 15 Updates
Ruby
Ruby hero Nerf

Adjustments applied to Let's Dance!, Be Good!.

All Documented Modifications (3)
Designer Note
Ruby can easily get Spell Vamp from Talents and Equipment in the early game, so we reduced her Base Spell Vamp. Since the short cooldown of her Skill 1 can keep her enemies slowed throughout the fight, we also adjusted the slow duration.
Base Spell Vamp: 10% → 5%
Slow Duration: 2s → 1s
Role: Fighter
Tier: C
Patch History: 9 Updates
Tigreal
Tigreal hero Adjusted

We're glad to see Tigreal back on the battlefield. Now that he can stun enemies with the first half of his Ultimate, it's much easier to use the skill. We want to keep that, but shorten the overall control effect.

Melissa
Melissa hero Adjusted

With our previous adjustments, Melissa was able to deal damage to enemy heroes from afar with bonus attacks against Muddles, simply by attacking without a target. And there's nothing the enemy can do about it.

Only basic attacks that have a target will trigger bonus attacks against Muddles, meaning basic attacks that don't have a target will no longer trigger this effect
