Keepsake

If you can, definitely. Inflicting Specialized Disable to ALL enemies is crucial.


🔹 Unit Overview:

A premium DPS + utility hybrid with incredible value in both PvE and PvP. His ability to inflict Specialized Disable on all enemies makes him meta-defining, especially in follow-up-heavy environments. When built properly, he not only amplifies your team’s damage through Specialized Shatter but also acts as a shutdown tool against key threats like Suiryu and KING.


✅ Pros:

  • Specialized Disable to ALL enemies
    → Completely shuts down enemy Follow-up mechanics. Huge counter to Suiryu, KING, and other Follow-up-centric units.

  • Specialized Shatter
    → Boosts your team’s total damage output. Works great in both burst and sustain teams.

  • Ultimate Follow-up mechanic
    → If faster than the enemy, he triggers a bonus Ultimate Follow-up after their action, making him a strong pressure unit.

  • Flexible in PvE and PvP
    → Great for boss fights, story, and Arena with consistent value regardless of mode.

  • Scales well with investment
    → KS and A2 significantly amplify his power and reliability.


⚠️ Cons:

  • High investment cost
    → Performs best with KS and A2. Without them, his utility and damage potential drop significantly.

  • Expensive to gear
    → Needs speed to activate Follow-up mechanics and offensive stats to stay relevant as DPS.

  • Resource conflict (especially for monsters)
    → Many recent top-tier units (Suiryu, KING, AS, Genos, Flashy, etc.) are hero-side, making it tough to split resources if you're already building them.

  • Upcoming URs to consider
    → Units like UR CE (core) and UR DSK may require priority, especially if you're limited on Black Tickets or upgrade materials.


💡 Summary:

If you can afford to build him, absolutely go for it.
His full-team Specialized Disable is incredibly strong in the current meta and gives you a massive edge, especially in high-level PvP. Just be mindful of how many resources you’re committing — and plan ahead based on your BT budget and whether you’re building toward hero or monster comps.
