Secret of Electrum and Score Gaining

Most people know basic things about electrum gain – you get 40 electrum for an EM against AI3, 120 for an EM against a False God, etc. Not many know the details of electrum gain behind PvP or Arena though, and even fewer know anything about how score is gained.

I have looked into the mechanics and formulas behind how much electrum and score is gained for a win. Here is what I have found.

Note that you gain back the score and electrum you lost when you entered the match before these formulas are applied.

Level 0: Trainer

Electrum: 1
Score: 1

EM

Gain an extra 1 electrum.
Gain no extra score.

Level 1: Random

Electrum: 1 + round-down(HP / 25)
Score: 1 + round-down(HP / 25)

EM

Level 2: Normal

Electrum: 5 + round-down(HP / 20)
Score: 5 + round-down(HP / 20)

EM

Level 3: Elder

Electrum: 10 + round-down(HP / 10)
Score: 10 + round-down(HP / 10)

EM

Double electrum gained.
Gain 15 extra score.

Level 4: Arena

‘bonus’ is the base reward of the league that you win against.

However, if the deck is rank 4-9, bonus is doubled.
If the deck is rank 3, bonus is multiplied by 6.
If the deck is rank 2, bonus is multiplied by 8.
If the deck is rank 1, bonus is multiplied by 10.

Electrum: -5 + round-down(bonus / 2 + bonus * (HP / 200))
Score: -5 + round-down(bonus / 2 + bonus * (HP / 200))
