You will receive zero Resources from successful Raids in only two cases:
- You have zero Raid Attempts remaining
- You have reached the Raid Resource limit
If Units return from successful Raids completely empty-handed, it is almost certain that you have hit one of these limits. While there are messages that will inform you when you have reached a limit, they will not be shown if you orchestrate Raids directly from the Battle Reports screen.
The amount of Resources you can gain from Raids is limited in the following way:
- You can claim a maximum of 500,000 Resources from Castles in any 24 hour period.
- You can claim a maximum of 50,000 Resources from a single Castle in any 7 day period
Please note that these numbers are aggregate (net) totals. They take into account Resources lost as well as Resources gained. Traded Resources are also included in the final total.
For example, if a player raids 10,000 Resources from you, you will be able to take up to 60,000 Resources from them within the next week, so that you will have gained a net total of 50,000 from them.
