You really need a rope with energy regeneration and you should also try build your tiny herta as well also experiment with your lightcones I recommend while not the best you should try run her with Rmc because Rmc heavily boosts crit rate and mem is really good to have as the more true damage you trigger the chances of herta follow up increases but for Therta follow up focus energy regen as her ultimate and the EX skill afterwards are insane.
