Guidance
Astra Yao is scored as a support and her build makes that unmistakable: she has no crit targets at all, and crit does not appear anywhere in her substat weights. A disc that would be excellent on a damage agent, loaded with CRIT Rate and CRIT DMG, is close to worthless here. If you are moving discs over from a DPS, this is the trap. What she wants instead is ATK, and a lot of it. Her ATK target is 3,430, among the highest of any agent on the site, and ATK% is her heaviest substat weight with flat ATK just behind it. Slot 6 accepting Energy Regen is the other support tell, though ATK% is accepted there too. Mindscape 2 gives her 467 flat ATK, which the rating folds in for you. That is around an eighth of her entire ATK target arriving for free, so an M2 Astra needs noticeably less from her discs to clear the same line.
