Pity (guaranteed grant after a set number of draws)

Estimated cost

Estimates at 300 JPY per draw. We do not describe only the lucky side.

Until one jackpot (100 fragments) for the selected character
Average about 100 draws (about 30,000 JPY)
Until one jackpot (100 fragments) for any character
Average about 50 draws (about 15,000 JPY)
Bringing one selected character from 0 to the final stage (stage 10, 600 fragments)
Average about 238.7 draws (about 71,597 JPY)
Lucky 10%: 167 draws (50,100 JPY) / Median: 240 draws (72,000 JPY) / Unlucky 10%: 318 draws (95,400 JPY) / Maximum (pity): 330 draws (99,000 JPY). Share reaching the pity: about 6.9%.

"From 0 to the final stage" assumes you keep selecting that character and use no fragments obtained through play. In practice, fragments are also obtainable through play (dungeon clears, weekly quests, mastery, the free track of the season pass, etc.).

If we change the odds, pity or other contents of the draw, we will announce it in the app and on this page at least 7 days before the change. As a rule we do not make changes unfavorable to users (lowering the odds of high amounts, raising the pity count, or lowering the selected character's probability).
