What is the best way to use the recruitment feature in Arknights?

### Recruitment Tips: 1. **Tags**: Focus on rare tags like 'Senior Operator'. 2. **Timer**: Set to 9 hours for higher rarity. 3. **Guides**: Use community resources to explore tag combinations.

Always aim for a 9-hour recruitment to maximize your chances of getting high-rarity operators. Use tags like 'Healing' and 'Ranged' for focused recruitment.
