The White Day 2026 limited SSR banner runs March 13–22, 2026, with hard pity at pull 28 (4,480 Diamonds) and a 50/50 system that makes worst-case guaranteed featured SSR cost 8,960 Diamonds (56 pulls). Soft pity activates around pull 20, progressively boosting SSR odds through pull 28. Here's what most players get wrong: locked Diamonds from events and missions count fully toward limited banner pulls — your White Day event rewards feed directly into your pity counter.
What Is the Pity System in Idol Party Diamonds?
Pity guarantees you won't pull forever without reward. Every pull accumulates toward a counter that triggers rate boosts (soft pity) and eventually a guaranteed SSR (hard pity). Understanding both thresholds is the difference between smart budgeting and an expensive mid-pity abandon.
Soft pity activates around pull 20 (~3,200 Diamonds). From there through pull 28, your SSR odds climb with each pull — you're no longer at the base rate.
Hard pity is the absolute guarantee: pull 28 delivers an SSR, no exceptions. That's 4,480 Diamonds from zero.
Why This Changes Your Pull Decisions
If you're at pull 22 and considering stopping, you're in the worst possible position. You've spent ~3,520 Diamonds, soft pity is actively working in your favor, but you have no guarantee yet. Stopping at pull 22–25 means paying the soft pity entry cost without collecting the benefit. Community consensus is clear: commit past pull 19 or don't enter the soft pity zone at all.
Always verify rates in the banner's probability table (the Details or Rates button near the pull interface). Official rates override any community estimate, including figures here.
White Day 2026 Banner Details
The banner window is March 13–22, 2026 — a tight 10 days. The featured idol is a support-type character that scales with 2–3 skill upgrades, valuable for gifting, affection mechanics, and stage performance. Not just a cosmetic pull.
The broader White Day 2026 event runs March 6–22, 2026 (ending 23:59 UTC), with server maintenance March 5 from 10:00–11:00 GMT+8. The White Valentine Couple Event overlaps March 12–22, directly relevant to your pre-banner Diamond farming.
Participating servers: Idol School, Shining Star, South East Asia Global (1001), and Middle East (1002).
This is a limited banner. The featured SSR isn't in the permanent pool. When it closes March 22, pity resets and doesn't carry forward — hard deadline, not soft.
On rate transparency: The pull 20 soft pity threshold and rate curve through pull 28 are community-observed, not officially published per-pull. Hard pity at pull 28 and the 50/50 system are officially confirmed. Weight the hard pity math heavily when planning — it's certain. Soft pity estimates are well-supported but not granular.
Soft Pity: When Your Odds Start Climbing
Think of it as a ramp, not a cliff. Pulls 1–19 run at base rate. Pulls 20–27 see incrementally rising odds. Pull 28 is 100%.
There's no safe stopping point between pull 20 and pull 27. You've already paid the soft pity entry cost. The only rational exits are before pull 20 (if saving) or at pull 28 (guaranteed).
Hard Pity & the 50/50 System
Pull 28 guarantees an SSR — but not necessarily the featured idol. The 50/50 system means there's a 50% chance it's the rate-up character and 50% chance it's a non-featured SSR. Hit the non-featured SSR at pull 28, and your next hard pity is guaranteed to be the featured idol.
After hard pity resolves, the counter resets to pull 1. No accumulation carries into the next cycle.
Locked Diamond Rules: What Counts Toward Pulls?
Locked Diamonds count fully toward limited banner pulls. Officially confirmed. Your White Day event rewards — distributed as locked Diamonds — are completely valid currency for the March 13–22 banner.
Locked Diamonds are earned through events, missions, gift codes, login bonuses, and achievements. The one restriction: they can't be used for non-gacha purchases like name changes (500 Diamonds). For banner pulls, the distinction between locked, free, and paid Diamonds disappears entirely.
White Day 2026 Locked Diamond Sources
F2P realistic target: 988 locked Diamonds (888 Consolation + 100 Participation) via solo NPC submission. This beats the partner-dependent Lucky Award by 388 Diamonds with zero coordination risk.
The Two Mistakes That Cost Players the Most
First: excluding locked Diamonds from pity math. If you have 988 locked and 3,492 paid/free Diamonds, that's 4,480 total — exactly one hard pity cycle. Players who forget locked Diamonds either over-spend on top-ups or under-pull and waste accumulated pity.
Second: pulling the standard banner during March 13–22. Standard banner pity is completely separate. Every pull there is a Diamond that doesn't advance your White Day counter.
If you're planning to top up before the banner, Idol Party Diamonds cheap recharge for White Day banner 2026 is worth checking early — settle funds before March 13, not March 21.
Pity Carry-Over Policy
No carry-over. Limited banner pity resets when the banner ends March 22, 2026. It doesn't transfer to the standard banner or future limited banners. Whatever pity you've built disappears at 23:59 UTC on March 22.
If you're at pull 15 on March 21 without enough Diamonds to reach pull 28, you face a real decision: top up to complete the cycle, or accept that 15 pulls (2,400 Diamonds) generated no SSR and no carryover value. This is exactly why the community advises completing your Diamond audit before March 13, not March 22.
Standard banner pity persists indefinitely — but it's a different counter entirely. Don't conflate the two.
To check your current pity count: navigate to the banner screen, find your pull history or pity tracker near the pull button, and count pulls since your last SSR on this banner type.
Pull Math: How Many Diamonds Do You Need?
Each pull costs 160 Diamonds.
Without an officially published base rate, a precise expected value calculation isn't possible. Practically: budget for hard pity (4,480 Diamonds) as your planning floor, not your ceiling.
Community estimates put realistic F2P total at 1,140–1,417 Diamonds across the full event (locked Diamonds, gift code, dailies, login bonuses, club rewards, achievement milestones). That's roughly 7–9 pulls. The gap between F2P accumulation and hard pity is approximately 3,080–3,340 Diamonds — about 19–21 pulls. Unless you're carrying a significant pre-event stockpile, F2P alone won't reach hard pity.
10-pull costs 1,600 Diamonds. No confirmed guaranteed SR bonus on multi-pulls in current data — pull in whatever increment fits your budget. Pity advances identically regardless of single vs. multi-pull format.
Spending Strategy: Should You Pull?
One honest question settles it: do you currently lack a support-type SSR? If yes, this idol's scaling with gifting, affection, and stage mechanics makes it high-value. If you already have a well-built support SSR, the opportunity cost of 4,480–8,960 Diamonds is real given future banners.
The 70/30 reserve rule: Never commit more than 70% of total Diamond reserves to a single banner. Keep 30% for the next rotation — otherwise you drain everything on White Day 2026 and can't participate in the next limited banner at all.
F2P decision framework:
Pull if: You lack a support SSR, can reach 4,480 Diamonds total (locked + free + paid), and have secured event rewards first
Skip if: You have a functional support SSR, or total Diamonds fall below 4,480 with no top-up planned
Never do: Pull the standard banner during March 13–22 to test your luck — separate pity pool, burns your White Day budget
Spending Tiers for Paying Players
If you haven't used your First Recharge Bonus, the 3,280 pack doubles to 7,872 Diamonds — enough to cover worst-case 8,960 with a small supplement needed. The 6,480 pack delivers nearly identical value but the First Recharge option is strictly better if available.
Recharge by March 18 at the latest. Community experience consistently warns about processing delays near deadlines. Don't leave top-ups for March 21–22. For players locking in value before the banner closes, Idol Party Diamonds top up discount before pity reset March 2026 offers competitive rates with fast delivery.

Frequently Asked Questions
Does pity carry over after White Day 2026 ends? No. Limited banner pity resets at 23:59 UTC on March 22, 2026. It doesn't transfer to the standard banner or any future limited banner.
Can I use locked Diamonds on the White Day 2026 banner? Yes — officially confirmed. Locked Diamonds from events, missions, login bonuses, and gift codes count fully toward limited banner pulls. The only restriction is non-gacha purchases like name changes. For banner pulls, locked and free Diamonds are functionally identical.
What is the SSR rate, and when does soft pity start? Hard pity at pull 28 is officially confirmed. Soft pity activating around pull 20 is community-observed. The exact base SSR rate and per-pull increase during soft pity haven't been officially published — check the in-game probability table for the official base rate.
How many Diamonds does a guaranteed SSR cost? Hard pity at pull 28 costs 4,480 Diamonds (28 × 160). If the 50/50 delivers a non-featured SSR, the second hard pity guarantees the featured idol — worst case 8,960 Diamonds across 56 pulls.
Is the White Day 2026 banner limited or permanent? Limited. The featured support-type SSR is exclusive to March 13–22, 2026, and isn't in the permanent standard pool. No confirmed rerun schedule.
Should I pull the standard banner while saving for White Day 2026? No. Standard banner pity is completely separate. Pulling it during the event burns Diamonds without advancing your White Day pity counter — one of the most common and costly mistakes during limited event windows.
