Cast Changes
- Modifies Merulina with: Merulina Augment: Yareli no longer rides Merulina.
- Rank up the augment to unlock the full effect values.
- Costs a mod slot (and capacity) — only equip it when the change matters for your loop.
Worth the Slot?
- Worth it when the augment’s change is central to how you play Yareli.
- Skip it if the base Merulina already does what you need and you’d rather keep the slot for survivability or strength.
Tips & Tricks
- Read the battlefield first — cast Merulina when it actually solves the room, not on cooldown habit.
- Pair Merulina with movement and energy economy so you’re not stranded after a big spend.
- On Steel Path, confirm whether Merulina still carries without strip, Viral, or a squad buff.
- If you never press 2, it’s the first Helminth candidate on Yareli.

Mod Scaling
Strength
- Improves Merulina’s damage or effect potency where Strength is listed on the ability.
Duration
- Duration is low priority on Merulina unless an augment or lingering effect needs it.
Range
- Range is usually dumpable on Merulina unless you feel the hitbox is too tight.
Efficiency
- Merulina costs energy each cast — Efficiency (or strong regen) keeps the loop comfortable on long missions.
Priority
Stack the stats that actually move this ability’s needle, then Efficiency for uptime.
Mission Use Cases
| Mission | How to Use It |
|---|---|
| Steel Path Survival / Defense / Disruption | Test whether Merulina still clears or enables clear when enemies are dense and overlevelled. |
| Mobile Defense / Excavation | Use Merulina to control or delete the swarm on the objective, then reposition. |
| Exterminate / Capture Speed Runs | Cast Merulina only when it saves time — skip it on empty tiles. |
| Spy / Rescue / Quiet Routes | If Merulina is loud or forces combat, save it for after the vault; if it’s stealth-friendly, use it to stay safe. |
Comparisons
- VS
Vs similar tools on other frames — Merulina is tuned for Yareli’s loop — don’t judge it as a standalone subsume without the rest of the kit.
