Enrichment allows you to increase the profitability of researchable Tier V–X vehicles using gold. There are two types of enrichment: temporary enrichment that is effective for 14 days and permanent enrichment. The increase in profitability does not depend on whether your tank is temporarily or permanently enriched.
An enriched tank earns more credits in battle while its resupply and repair costs remain unchanged. This means that not only will your earnings increase, but also your net income from this vehicle will go up.
The screenshot below shows an example of how enrichment affects income using the total results of ten battles in the STA-1.
How to Enrich a Tank?
1. Select a vehicle between Tier V and X and go to the Upgrades menu. Tap Enrich.
2. The window will offer you the choice between permanent and temporary enrichment. Select the desired option and tap Enrich.
3. Confirm the purchase.
This enrichment is valid for 14 days and is available for all Tier V–X researchable vehicles:
