Battle fund
See also: Crystals
The most common and easy way to earn crystals in ProTanki is to complete battles.
When players carry out active actions during the battle, the Battle Fund statistic increases.
At the end of the battle, the fund is distributed among all players remaining in the battle according to certain rules.
The battle fund statistic can be seen at the bottom right corner of the Battle HUD as shown:
Accumulation of Battle Fund
Scenarios for Fund accumulation
Battle fund accumulates when players perform the following active actions in battle:
- Destroying opponents
- Deliver flags
- Capturing or neutralizing a point
Note: Returning flags and healing teammates with Isida CANNOT generate Battle Fund.
Growth rate of Battle Fund
Rank
See also: Ranks
The number of crystals added to the fund depends on the ranks of the players in the battle. As the ranks of the players increase, the battle fund accumulated increases.
The following table shows the amount of Base fund for each rank in Deathmatch:
| Base Fund | |
|---|---|
| Rank | Crystals added |

- When a player is destroyed, the amount of base fund corresponding to the player's rank is added to the Battle fund.
- When a flag is captured, the sum of base funds corresponding to each player in the enemy team is added to the Battle fund.
Hull
See also: Hulls
The amount of crystals added to the battle fund depends on the Hull of the destroyed tank. Light hulls such as Wasp and Hornet only adds 80% compared to the amount when destroying medium or heavier hulls such as Hunter.
Previously, destroying heavy hulls such as Titan and Mammoth adds more to the battle fund, but this feature has been removed from the game.
It is important to note that the Modification level of the Hull is not factored into the calculation. Therefore, destroying a tank with Hunter M0 adds roughly the same amount of fund as destroying a Mammoth M3 (Provided that the two tanks are at the same rank).
Battle Settings
See also: Battles, Battle modes
The following modes affect the rate of accumulation of Battle fund:
- DM: +10%
- TDM: +20%
- CTF: -10%
- CP: 0%
For gamemodes involving team play, it is possible to get a 50% increase in fund gain when multiple teammates destroy an enemy tank.
Battles with the Parkour format do not accumulate any fund.
If the Crystal boxes setting is disabled, there is a 50% increase in battle fund.
However, in certain situations, it might be better to enable the setting,
as the total value of Crystals obtained through Gold and Crystal boxes may be great enough to compensate for the lower fund.
For more information, you can read the following guide: Should I Disable Crystal Boxes?
There are certain restrictions regarding the selection of turrets in battles.
When these restrictions are met, fund gains will be heavily penalized.
- If the ratio of players equipped with Firebird across a battle is sufficiently high.
- This is to prevent players from farming large amounts of Experience and Crystals with Wasp Fire or Hornet Fire.
- If the ratio of players equipped with Railgun or Shaft in a Private Madness battle is sufficiently high.
Festivities

During special festivities and promotions, the fund growth rate may increase by multiples.
Distribution of Battle Fund
When the battle ends, the accumulated fund is distributed to every remaining player in the battle.
In Deathmatches, crystals are distributed based on a hidden score statistic, which can be approximated by the number of enemies destroyed. However, this approximation can become unreliable if the player destroyed multiple light hulls or self-destructed many times.
In team modes, the winning team receives the largest portion of the fund. The amount is determined by its lead over the losing team, and can range from 60 to 80%. The remainder of the fund is taken by the losing team.
Within each team, the fund is distributed proportionally based on their battle score. It is possible for a player from the losing team to get more crystals than the 1st player in the winning team, provided that the losing player accounts for the majority of score across their team.
Note: A player cannot receive any crystals from the fund without any score.
If they are the only player in the team, then all the crystals that are allocated to their team will simply go to waste.
On the contrary, if the battle ends with every player on the same team, the other empty team will not take away any crystals.
