Resource Stages are repeatable operations designed to provide specific materials for operator development. They are accessible from the 'Operations' menu under 'Supply Operations'. There are several types of resource stages, each dropping different materials:
- LS (Lungmen Street): Drops LMD, essential for promotions and skill upgrades.
- CE (Combat Experience): Drops Battle Records (EXP cards) for leveling up operators.
- AP (Annihilation Preparation): Drops various promotion materials and skill books.
- SK (Skill Summary): Drops Skill Summaries for skill level upgrades.
- CA (Chip Assault): Drops Operator Chips for Elite 1 and Elite 2 promotions.
Prioritize farming these stages based on your current needs. Early on, LS and CE are crucial. As you progress, AP, SK, and CA become more important. Each stage has different difficulty tiers, with higher tiers offering better Sanity efficiency. Always aim to clear the highest tier you can reliably auto-deploy.
