Crystal Drops

Grindfest is well known as a battle mode design to give players a lot crystals, which they may use to upgrade their monsters.
The base number of crystals dropped increases with current difficulty and number of rounds played. This caps at round 500.
The formula for crystals dropped is as follows:
Crystal Drop = floor((crystarium) * (diffmod + min(gfbonus, (gfbonus / 500) * round)))
- floor is special function, which rounds number down, toward zero, to the nearest multiple of significance.
- min is special function, which choose minimal one between numbers.
- crystarium is x2, x3, x5, x7, x10 for each rank of the Hath Perk, respectively. Otherwise it is x1.
- diffmod is x1 - x3 depending on difficulty (see table below).
- gfbonus is x0.5 - x2 depending on difficulty (see table below).
- round is your current round in Grindfest.
| Difficulty | Diffmod | Gfbonus |
|---|---|---|
| Normal | x1 | x0.5 |
| Hard | x1.2 | x1 |
| Nightmare | x1.4 | x1 |
| Hell | x1.7 | x1.5 |
| Nintendo | x2 | x1.5 |
