Zenless Zone Zero 2.0 introduces two powerful new Drive Disc sets: [As Steady as a Mountain] and [Boss of the Hills]. How strong and versatile are they? Which characters benefit most from each set? Let’s break them down in this quick overview!
As Steady as a Mountain (Cloud Set)
2-Piece Bonus
Currently the only Drive Disc set that boosts HP. Since Yi Xuan converts HP into PEN Ratio through her core mechanics, HP-based stats provide excellent value for her. This 2-piece bonus is highly prioritized for Yi Xuan but has very limited general usability beyond her.
4-Piece Bonus
The 4-piece effect is highly specialized: Using an Enhanced EX Special Attack, Chain Attack, or Ultimate grants 4% Crit Rate each. At max stacks (12% Crit), it also gives 10% PEN DMG.
PEN DMG is a newly introduced multiplier type that stacks independently from other damage bonuses, resulting in exceptionally high actual gains. This makes it a must-have set for Yi Xuan.
Farming Notes
Designed specifically for Yi Xuan, this set offers 10% HP, 12% Crit Rate, and 10% PEN DMG—a very high-value combination. While it’s a top-priority farm for Yi Xuan mains, its lack of flexibility makes it less attractive for general farming.
Best Users (2-Piece): None at the moment
Best Users (4-Piece): Yi Xuan only
Boss of the Hills (Mountain King Set)
2-Piece Bonus
After several patches, we finally get a second Break-focused Drive Disc. The 2-piece bonus gives +6% Daze (Stagger Value). Even without the 4-piece effect, it pairs nicely with existing sets like Shockstar 4, serving as a solid universal sub-piece for Break characters.
4-Piece Bonus
This set gives Break characters a team support role: When the user inflicts Daze, using Enhanced EX Special Attacks or Chain Attacks grants the whole team +15% Crit DMG. If the user’s Crit Rate is over 50%, the buff becomes +30% Crit DMG—a huge boost for high-crit Break characters.
This makes the set perfect for Break characters who naturally stack Crit, especially off-field supports.
Farming Notes
The 2-piece bonus is universally usable for all Break characters. The 4-piece adds strong utility. Right now, only Grace (a.k.a. Nicole, aka Bangboo’s Trigger) stacks high Crit naturally. Farming this set is highly recommended if you want to boost her support potential.
What’s more, Orange Bangboo (Juefufu), a new off-field Break unit in 2.0 Phase 2, is expected to pair well with this set. Based on visuals alone, it even looks like it’s his signature set.
In general, Break characters who can’t fully utilize Shockstar 4 can shift to Boss of the Hills—just make sure to push Crit Rate over 50% later on.
Best Users (2-Piece): All Break characters
Best Users (4-Piece): Juefufu (Orange Bangboo), Trigger, Lycaon, Rina, Corin, Puppey, etc.
Final Thoughts
Both new Drive Disc sets introduced in Version 2.0 are powerful:
[As Steady as a Mountain] is a Yi Xuan-exclusive powerhouse—a must-farm for her mains due to its exceptional synergy and stats.
[Boss of the Hills] offers broad usability across all Break characters, and its team-oriented 4-piece bonus makes it a long-term staple set, especially for high-Crit Break builds.
