## Cost to power up a cardEdit

+0 | +1 | +2 | +3 | +4 | +5 | |
---|---|---|---|---|---|---|

D | 0 | 100 | 200 | 300 | 350 | 500 |

C | 0 | 500 | 750 | 1,000 | 1,500 | 2,500 |

B | 0 | 1,000 | 1,500 | 2,000 | 3,000 | 5,000 |

A | 0 | 1,500 | 2,250 | 3,000 | 4,500 | 7,500 |

S | 0 | 2,000 | 3,000 | 4,000 | 6,000 | 10,000 |

- One card will be consumed per power up attempt.
- Gold cost is irregardless of the success rate. So it'd cost you 500 gold to upgrade a C rank card 1 level if you use a C rank card (100%) or a D rank card (33%)

## Cards Needed to Gain RankEdit

**Warning**: Do not look unless you're immune to horror, you have a plan, you want to give up, or you want a reason to spend real money. Refer to the Tips section on how to make an S-rank character with only 5 million gold.

- Assumptions:

To read the charts, start from the desired rank. And then read across. That's it. For instance, to obtain an S-rank card, you will need to start with 20,736 D-rank cards. If you should have any B or C-rank cards, this number is decreased. In other words, you do NOT need 20,736 D-rank cards, 1,728 C-rank cards, 144 B-rank cards, and 12 A-rank cards to create an S-rank card. 20,736 D-rank cards will be enough.

Rank | Cards Needed | Power-Up Cost | Card Cost | Total Cost |
---|---|---|---|---|

D | 12 [1 x 12] | 2,900 | 36,000 | 38,900 |

C |
1 | -- | -- |

## TipsEdit

- Powering C-Rank cards should be done using chance method.
- Buying cards and powering using 100% chance will cost you 38,900 gold to create each B-rank card used to upgrade because you need 12 D-rank cards.
- Powering a C-rank card to +5 using this method will cost you 194,500 gold.

- The chance method requires 8 cards at most.
- Each failure grants you 15 power points. 100 / 15 = 6.6667 which rounds up to 7 cards needed for 100 power points. The next upgrade afterwards (8th) will have have a 100% success chance.
- The 8 upgrades at 2,500 gold per power-up comes out to 20,000 gold. You need 8 cards, which adds an additional 24,000 gold. In total, each extra power up will cost you a maximum of 44,000 gold.
- Powering a C-rank card to +5 using this method will cost you 170,000 gold [(500 * 8 + 24000) + (750 * 8 + 24000) + (1000 * 8 + 24000) + (1500 * 8 + 24000) + (2500 * 8 + 24000)].

- Buying cards and powering using 100% chance will cost you 38,900 gold to create each B-rank card used to upgrade because you need 12 D-rank cards.
- Powering B-Rank cards should be done using the chance method.
- Buying cards and powering using 100% chance will cost you 479,300 gold to create each B-rank card used to upgrade because you need 144 D-rank cards.
- Powering a B-rank card to +5 using this method will cost you 2,396,500 gold.

- However, using the chance method only requires 16 cards at most.
- Each failure grants you 7 power points. 100 / 7 = 14.28 which rounds up to 15 cards needed for 100 power points. The next upgrade afterwards (16th) will have a 100% success chance.
- The 16 upgrades at 5,000 gold per power-up comes out to 80,000 gold. You need 16 cards, which adds an additional 48,000 gold. In total, each extra power up will cost you a maximum of 128,000 gold.
- Powering a B-rank card to +5 using this method will cost you 440,000 gold [(1000 * 16 + 48000) + (1500 * 16 + 48000) + (2000 * 16 + 48000) + (3000 * 16 + 48000) + (5000 * 16 + 48000)].

- Buying cards and powering using 100% chance will cost you 479,300 gold to create each B-rank card used to upgrade because you need 144 D-rank cards.
- Powering A-Rank cards should be done using the chance method.
- Buying cards and powering using 100% chance will cost you 5,776,600 to create each A-rank card used to upgrade because you need 1728 D-rank cards.
- However, using the chance method only requires 51 cards at most.
- Each failure grants you 2 power points. 100 / 2 = 50 cards needed for 100 power points. The next upgrade afterwards (51st) will have a 100% success chance.
- The 51 upgrades at 7,500 per power-up comes out to 382,500 . You need 51 cards, which adds an additional 153,000 . In total, each extra power up will cost you a maximum of 535,500 .
- Powering an A-rank card to +5 using this method will cost you 1,721,250 [(1500 * 51 + 153000) + (2250 * 51 + 153000) + (3000 * 51 + 153000) + (4500 * 51 + 153000) + (7500 * 51 + 153000)].
- To make this even cheaper, save all C-rank cards that you manage to obtain from the card packs. If you save these cards until it is time to upgrade the A-rank card from +4 to +5, your final cost will end up being: 1,353,750 [(1500 * 51 + 153000) + (2250 * 51 + 153000) + (3000 * 51 + 153000) + (4500 * 51 + 153000) + (7500 * 16 + 48000)].
- Generally you will not be able to save enough C-rank cards to upgrade from +3 to +5. But if you do manage to collect around 30ish C-rank cards, it's usually enough to complete both upgrades. However, it would be better to save them for that second A-rank card that you're planning to upgrade.
