Detonator with a good, but conditional, damage amp.

A

(S- at R3)

+Good AoE on active with flexible targeting

+Extremely strong damage amp equipment for team support if set-up (see Dayna)

+Significantly better chain combo than Dayna

+Refinements allows her to deal very respectable damage by herself

-Lackluster damage on active

-Somewhat reliant on BT5 (though not as much as Dayna) to maximize her output

-Active also doesn't set up equipment buff, unlike Dayna, which reduces her consistency

>Corporate wants you to find the difference.
>They're exactly the same!

Robyn has the exact same equipment as her sister Dayna, a 5% team-wide damage amp. So, just like Dayna, she's a sleeper sub-DPS capable of bringing out some great numbers across the rest of your team.

The primary difference between her and Dayna are the secondary effects of their skills and their chain combos. Dayna has a far worse chain but her skill guarantees the trigger of her equipment. Robyn loses that guarantee for an exceptionally strong chain. I don't think this is enough to meaningfully differentiate their damage profiles, but your mileage may vary. Do note that Robyn may have a better niche in forest, which lacks as many absolutey busted detonators and has more ways of setting up tiles underneath enemies via units like Hiiro and Gabriel (though wasting a Hiiro charge on an unusable tile is... questionable).

Not meta defining, but way better than most tier lists suggest.
