To guarantee UR Alina's exclusive Vibration Arms, Rita (Precision Bombing), in Echocalypse: Scarlet Covenant, budget between 70 and 140 weapon summons. Pull on the dedicated Vibration Arms banner only after you already own UR Alina. If you do not have enough currency to reach the 140-pull safety threshold, hold your resources for a rerun to avoid losing progress to banner variance.
Prerequisites and Banner Rules
Do not convert Iridis or specialized weapon draw tokens until UR Alina is in your squad. Signature Vibration Arms passives remain dormant when equipped on any other character.
The weapon banner operates independently of character recruitment:
- Separate Currencies: Weapon draws require dedicated summon tokens or premium currency rather than standard character contracts.
- First Pity Threshold (50–70 Pulls): Reaching this tier triggers your first high-rarity drop, which may award the featured weapon or an off-rate SSR piece.
- Hard Guarantee Buffer (140 Pulls): Committing a full 140 summons accounts for worst-case roll outcomes, securing the featured Rita drop if the first pity roll yields an off-rate weapon.
- Banner Mileage: Unsuccessful pulls accumulate mileage tokens and surplus materials that can be applied toward weapon exchange or modification items in active event shops.
140-Pull Investment Breakdown
Tracking resource milestones across 14 ten-pull sets helps manage expectations when rolling for Rita:
| Summon Bracket | Expected Milestone | Secondary Account Yield |
|---|---|---|
| 1–40 Pulls | Rare base equipment and lower-rarity fodder | Basic modification parts and scrap |
| 50–70 Pulls | First major pity roll (Rita or off-rate SSR) | High-tier enhancement materials |
| 80–110 Pulls | Progression toward the second guarantee | Duplicate weapon shards and tokens |
| 120–140 Pulls | Guaranteed featured Rita drop or first duplicate | Surplus weapon EXP and exchange currency |
When to Stop Pulling
Stop summoning as soon as you secure a single base copy (0-Star) of Rita.
A base copy immediately unlocks Alina's character-specific skill modifiers, attack scaling, and passive resonance bonuses. Pushing beyond 140 pulls to chase duplicates increases stat percentages—such as pierce, critical rate, and initial rage—but delivers diminishing returns compared to the raw value of the initial unlock. Unless you are optimizing for top-tier competitive PvP mirrors, save your remaining currency for upcoming character banners once the 0-star weapon is acquired.
