There is a rather unmissable banner draped across the front page of the official Raven 2 community these days. It’s a heads-up for a massive update coming on May 27, which marks the game's second anniversary. To ramp up the excitement, the team is busy with a slew of events and has a developer live stream locked in for the evening of May 14. While digging through the recent event and content schedule, I’ve spotted a clear link to the 'Ultimate Coupon'—the secret sauce here is hoarding as many summon scrolls as you can to inflate your contract summon and synthesis counts.

Q. So, what’s on the to-do list before May 27?
A. Wrap up the pre-anniversary events. Seriously, focus on those summon scrolls and coupons.

Most of the current Raven 2 events are set to conclude on May 27, including the '14-Day Blessing Attendance', 'Blessings After the Decisive Battle', and the 'Blessing Subjugation Missions'. The real prizes to chase here are the 'Grand Festival Invitation' (used for shop exchanges), the 'Faded Pouch' crafting material, and the 'Raven 2 Special Coupon: Equipment Exchange Ticket'.

If you look at the event rewards, it’s all about the summon scrolls. The event shop’s premium items—like the '2026 Ancient Vault', 'Pre-anniversary Mysterious Golden Pouch', and 'Lucky Summon Box: Rare'—are packed with them. The 'Lucky Summon Box: Rare', in particular, is a steal; it lets you pick a top-tier 11x summon scroll for your Class, Servant, or Stella with high probability. Nabbing a Hero-grade item is just the cherry on top.The pre-anniversary Golden Pouch crafted from Faded Pouches is essentially the same—a randomized box that has a decent chance of dropping an 11x summon scroll of at least High grade.

More summon scrolls mean more opportunities for contract summons. As mentioned during the 2026 New Year Developer Live, the 'Ultimate Coupon' is a special gift saved for anniversaries and the like. Given that previous coupons allowed for Class/Servant re-contracts and Stella re-synthesis, the strategy is simple: hoard scrolls now, then leverage them for those re-tries. Stockpile while you can.

Furthermore, Raven 2 is running a 'Special World ZERO Coming Soon Login Reward' from May 9 to 16. Log in at the specified times to snag 'Task Force Coins' and other goodies. You can trade these coins in the shop for various summon scrolls—another golden opportunity to prep for that Ultimate Coupon.

Don't forget to claim the 'Raven 2 Special Coupon: Equipment Exchange Ticket' on the 7th day of the 14-day blessing event. You’ll need it to craft an equipment restoration ticket after the May 27 update. If you know any friends eyeing a return to the game, tell them to log in for seven days so they don't miss out.

Q. Are there any other events ending on the same day?
A. Not an event per se, but the current season of the Tower of Chaos is closing its doors.

Coincidentally, Tower of Chaos Season 11 ends on May 27. Once it’s over, any extra entry tickets and Chaos Coins will be rendered useless, so spend them. The Chaos Coin shop sells 'Lucky Summon Support: Season 11', 'Lucky Summon Box: Rare', and 'Top-tier Weapon Resonance 11x Summon Scroll' with purchase limits of 1, 20, and 5 per server, respectively.

The safest bet? Grab one 'Lucky Summon Support: Season 11' and hoard as many 'Lucky Summon Box: Rare' items as possible. The former guarantees a 'Blessing 1x Class/Servant Summon Selection Box' and one 'Lucky Summon Box: Hero'. Opening the Hero box nets you at least two more selection boxes, giving you 22 pulls for top-tier gear. Since the Ultimate Coupon is all about rerolls, this is a perfect synergy.

Also, you might want to hold off on spending your Chaos Coins until just before the update drops on May 27.This is specifically for the 'Top-tier Weapon Resonance 11x Summon Scroll'. It’s a newer category that adopted the contract summon system, but we aren't yet sure if the anniversary Ultimate Coupon will cover it. It’s worth waiting for the developer notes to clarify before blowing your stash.

If you have immediate needs that prevent this strategy, don’t stress—just stick to your plan. The new Tower of Chaos season will kick off after the May 27 update, giving you another window to farm coins and prep for future coupons.

Q. But I want to burn through my summon scrolls and contract summons now!
A. Hold your horses; we don't know the tracking period yet, and they might be tied to anniversary missions.

You’ve stockpiled a mountain of scrolls, and the itch to use them is real. I’d advise holding off until after the update, or at the very least, avoid doing any contract summons or Stella syntheses beyond Stage 2.

Why the caution? Anniversary updates often come with mission boards that reward you for completing specific tasks, including—you guessed it—using summon scrolls or acquiring Classes/Servants/Stellas. You’ll want those pulls ready to tick off those boxes instantly. A quick tip from past experiments: Class/Servant contract summons count toward 'acquire' missions, but Stella synthesis does not. Keep that in mind.

As for skipping Stage 3+ summons and syntheses, we don't know if the Ultimate Coupon will retroactively count your activity. While it’s likely they’ll track the two weeks leading up to the update, why risk it? Stages 1 and 2 should be safe, and for the record, previous Ultimate Coupons didn't factor in special Class or Servant summon history anyway.
