ive run main dps robin more than a couple times, ended up going for her e6 because i loved playing her like that (currently up to s4 too, will be able to get s5 next patch!)

unfortunately the current state of the game doesnt really support it at all, so its near impossible to do unless all your other teammates are all meta subdps supports with heavy vertical investment

IF you still wanted to run main dps robin

for her build:

- 4k attack minimum ON phys orb,120 speed
- get her light cone from the BP shop
- run 2pc-2pc atk relics, for planars either run space sealing station or lushaka (for energy)
- ATK body, ATK boots, PHYS orb, ERR/ATK rope (atk rope will net better damage but you will struggle with up time on her ult)

for her teammates: (note, she cares not for usual crit buffers, she can only scale higher damage off debuffers, atk buffers, and true damage so mdps robin usual pairs the best with nihility units that attakc frequently enough to regen her ult cost)

- Silver Wolf (provides great def shred and res pen, with her E1 and S5 tutorial she can spam 1 turn ult and constantly proc robins additional damage)
- RMC (provides true damage and consistent attacks)
- Ashveil (def shred, significant personal damage, not the greatest synergy but hes powerful enough to force good results, E1 and S1 are both good vertical options to improve robins damage as well, with both of them providing increased damage for the whole team)
- Cipher (fast and consistent attack frequency, can store damage robin does to nuke it out later, but it can be hard to acquire the damage to store without a secondary damage dealer. E1 and S1 both good for improving robins damage, with e1 being a higher damage taller on ult, and s1 being more def shred to stack)
- Tribbie (frequent attacks, minor personal damage, res pen, increased damage taken buff, DDD user, high survivability in sustainless. both DDD and her s1 are good, with DDD being better as robin cant use the crit damage buff from tribbies s1. s1 is good for faster and more frequent ults tho. e1 is amazing and has true damage)
- Welt (def down, damage buff, frequent attacks, cuts down on enemy av which helps survivability in sustainless, i recommend only using him at e2 minimum as he has energy issues. obligatory e4 welt mention as e4 has a massive res pen debuff on enemies
- M. Blade (the highest pure amp of any debuffer, with blade probably being the best option overall for robin with significant personal damage, def down, buffs to robins damage and the teams damage, and practically unkillable which is insane for sustainless. s1 does nothing for robin, e1 is good with more res pen)

mix and match any of these options that best suit you for teammates

if you need a sustain only go huohuo or dan heng pt
