While Shenhe’s cooldowns make her Particle generation per minute lower than other Cryo units with lower cooldowns (for example compared to Rosaria who also generates 3 Particles per Skill on a 6 second rather than Shenhe’s 10 second cooldown), Shenhe gets a lot of reward from swapping her in to use her Skill off-cooldown without consuming significant field time. Practically, using her press Elemental Skill twice per rotation, (generating 6 Cryo Particles) is enough to make her Energy generation acceptable. Favonius Lance is one of her best weapons and boosts her battery capabilities even further.
