The calendar runs a six-week cycle, and it pays to raid with it rather than against it. The week turns over on Sunday at midnight, Israel time, and the Calendar screen on the main menu shows the current week plus the next five — so you can see a boost coming and level into it.
| Week | Element | What it does |
|---|---|---|
| Inferno Week | Fire | Its titans hit harder and their skills do more |
| Riptide Week | Water | As above, for water |
| Tempest Week | Air | As above, for air |
| Bedrock Week | Earth | As above, for earth |
| Plague Week | Toxic | As above, for toxic |
| Harvest Week | — | No element boost — everyone's loot and craft progress rise instead |
If you own a titan of the boosted element, equipping it that week is free power. If you are deciding who to level next, the calendar is a good tiebreaker. Harvest Week is the week to push raids and bank crystals.
