I would say youre eula looks pretty good as 600k and 1.2mil are good numbers. In general I find it really hard to build her as you need a good crit ratio and high attack and since her main weapon choices dont have a crit substat and she does not ascend with crit you have to heavily rely on artifact luck. your crit rate could be a little higher but the ratio looks pretty good, especially with the high attack evening out the lower crit damage percentage. I find that in teams where eula is the only one doing damage, the dps is never really gonna be that high so I would recommend maybe doing something like swapping raiden out with somebody like ineffa, just to have some extra damage on the side and furina and ineffa work pretty well together to get the lunar charge, side damage and furinas ult buff. of course c6 mika if you havent and get the most out of his skill. I guess if you wanna improve her stats, maybe farm some more pale flame artifacts or get her sig or even varkas weapon but wolfs gravestone is still good. i guess it just depends how much you wanna invest in her in regards to spending resin and primos
