Mudrock Talents & Skills Breakdown

Most Juggernaut Operators face issues with HP recovery and survivability. So, how does Mudrock solve this? In fact, her talents and skills are the absolute core of her survival, make her formiable Tank.

Talent 1:Ward of the Fertile Soil

Once deploying Mudrock, she instantly gains one Shiled. As time goes by, she will add extra Shield. One stack of Shield requires 9 seconds. It can stack up to a maximum of three times, that is absorbing 3 hits of damage. When Shiled is broken, restore 15% of Mudrock's max HP. Mudrock doesn't takes damage directly, while she regenerate Shiled to greatly relieve pressure. As a result, when facing high-pressure stage, she has a more outstanding performance than Defender who need healing.

Talent 2:Unshakable Solidarity

This is easy-to-understand Talent - Takes 30% less damage from Sarkaz enemies. It allows Mudrock to reduce damage taken and handle Sarkaz enemies with ease. Don't worry. There are many threatened Sarkaz enemies in Arknights. So, Mudrock becomes the first choice in these stages.

Unshakable Solidarity

Skill 1 : DEF Up γ

Mudrock's first skill is simple like other Operators. Players need to manually activate this skill to increase DEF by 30%~100% (Depend on Rank). However, this simple skill with Unshakable Solidarity makes her unparalleled when facing Sarkaz enemies. Upon triggering DEF Up γ, her body will be surrounded by blue highlight.

Skill 2:Crag Splitter

A auto-trigger skill restores 5% of max HP, deals AoE damage to enemies on the ground, and executes 30% chances of stun. The designer creates an excellent and well-suited skill for Mudrock. It significantly enhances her survivability since this skill point increase for each hit, allowing her to clear up mobs and heal herself. To put it simply, the more hits she can take, the higher damage and more CC she can deliver.

Skill 3:Bloodline of Desecrated Earth

The Bloodline of Desecrated Earth is an interesting mechanics that has two stages. Mudrock is immobilized and immune to all damage for 10s at stage 1, while the enemies are slow down in range. Afterwards, she stuns the range of enemies and dealing devastating damage to them. Meanwhile, she improves ATK speed by 30%, increases DEF by 50% and blocks all enemies.

The power of this skill lies in that she is virtually unkillable once activating it even though she cannot be healed. She can also rely on the shield to maintain the tempo, making her an extremely stable CC Tank for high-pressure situations. Beware, you should know the timing to counter enemies.

Note: Prioritize Skill 2 to bring CC and AoE damage to enemies (Elite 3 is the best). The progression of Skill 1 and 3 offers a minor boost, but Skill 1 takes precedence over Skill3.

Mudrock Module X or Y

Whether players want to choose X Module or her Y Module is a complicated question. Before selecting module, you ought to carefully consider her responsibility in your squad. Because her module are categorized into two parts for different usage. One makes her a tank, another one makes her a bruiser.

UNY–X:Spreading Roots of Soil and Stone

UNY-X is suitable for players who are relatively conservative and use Mudrock for solo blocking and high-pressure maps. This is especially reccomended if you lack an excellent Defender and need main Tank, because it improves survivability and ensures stable skill cycle.

Speciaty:

  • Increase HP and DEF
  • Enhance the effect of the Shield and speed up Shield generation
  • Best synergy for Skill 2 to quickly clear up mobs

UNY–X:Spreading Roots of Soil and Stone

UNY–Y:Wisdom of the Fertile Earth

This setup is suitable for players who want Mudrock to function as a hybrid damage dealer. Since this relies only on her inherent survivability, she performs better in scenarios where the enemy attack frequency is low.

Specialty:

  • Increase ATK & DEF when there are no allies in the surrounding 8 tiles
  • Increased Damage to Non-Sarkaz enemies
  • Takes 33% less damage from Sarkaz enemies
  • Smoother AoE damage output
  • Best synergy for Skill 3

Team Comps Recommendation

Mudrock doesn't receive healing, so her team comps differs from conventional Defenders. She shines when teammates help her control the battlefield and maintain a stable combat rhythm.

Crowd Control Team

Mudrock + Suzuran + Angelina + Magallan + Eyjafjalla

These operators limit enemy in Mudrock’s attack range. This gives Mudrock’s Skill 2/3 AoE hits and stuns more consistency, allowing her to cycle her shields comfortably and suppress waves with minimal risk. This setup requires Mudrock's X module for higher defence.

Damage Dealer Team

Mudrock + Surtr + Surtr Alter + Chen + Mountain + Gavial the Invincible

Mudrock handles mitigation, control, and tempo management. When she locks enemies in place or slows down their approach, DPS units can burst targets more efficiently and safely.

Conclusion

Mudrock is an 6-star Juggernaut Defender with strong abilities & control and outstanding base stats in Arknights. However, she demands higher DP cost, and her focus on solo combat makes her difficult to collaborate for the beginners. Therefore, we highly recommend players to progress Mudrock in late game.
