Endless Challenge

Endless Challenge is the ranked, no-finish-line version of Interview Trial, Bloody Battle and Double Clash. Here's who gets in, and what each rank bracket actually pays.
Endless Challenge takes three modes you already play and removes the finish line. There’s no stage to clear: you push until you fail, and your result is scored against everyone else’s on a leaderboard. Three modes rotate through it one at a time, each on its own window.
The three modes it rotates through
Endless Interview Trial. The Shadow Sabbath spawns alongside the usual enemies, and the moment you wipe a wave the next one arrives with no pause at all. You’re scored on how many waves you push back.
Endless Bloody Battle. Every session hands out the same fixed buffs, so nobody gets a better draw than anyone else. You’re scored on how many waves you clear inside the time limit.
Endless Double Clash. You field several teams, each with its own requirement to meet, and you play out every fight. You’re scored on total time, so roster depth matters here as much as the strength of your best five.
Who can get in
Two gates, and you need both: your server has to have been open a minimum number of days, and you have to have already cleared the required stages of that mode in its normal form. If you’re still working through Bloody Battle or Double Clash, the Endless version of it stays locked whatever your account level says.
What the ranking pays
Every session ends with rewards handed out by leaderboard position. All three modes use the same seven brackets, and the payout doesn’t change between a mode’s two difficulty groups. This is the Interview Trial table:
| Rank | Reward |
|---|---|
| 1 to 3 | “Endless: Interview Trial” avatar frame, its chat bubble, 200 Stone of Destiny · 1,000,000 Coins |
| 4 to 10 | Chat bubble, 180 Stone of Destiny · 900,000 Coins |
| 11 to 100 | Chat bubble, 160 Stone of Destiny · 800,000 Coins |
| 101 to 1,000 | 140 Stone of Destiny · 700,000 Coins |
| 1,001 to 3,000 | 120 Stone of Destiny · 600,000 Coins |
| 3,001 to 5,000 | 100 Stone of Destiny · 500,000 Coins |
| 5,001 to 10,000 | 80 Stone of Destiny · 400,000 Coins |
Two things are worth reading off that table. The avatar frame never appears again below rank 3, so it’s the one reward you can’t reach by grinding. And the curve underneath it is gentle: finishing 5,000th still pays 80 Stone of Destiny against the top three’s 200. Placing at all is worth far more than placing high.
On top of the ranking, each mode carries one-time quest rewards and stage-clear rewards while it’s live, so a single honest run already pays before the leaderboard even closes.
How to play it well
Treat the leaderboard as a bonus rather than the goal. The 5,001 to 10,000 bracket is wide enough that almost anyone who plays a session lands inside it, and the gap from there to the very top is 120 Stone of Destiny. Clear the one-time quest rewards, push until the waves outscale you, and stop.
The exception is Endless Double Clash. It scores you on total time across several teams, so it’s the one that rewards a broad roster rather than a single invested five. If you’ve been spreading investment around rather than funnelling it into one carry, that’s the session where it pays off.
