My bride hildr is not uncapped at all who is a better option to use for this ragna
Simply put your other best options are...Sniper Hildr IgnitedBastetCleopatra Resurrected FrejThat's the order from top to bottom.If you use Bastet only use her tap skill, she's a speedster. Use "Centennial Vow" carta with her.If you use Cleo, use the same carta. Cleo's tap gives her focus. If you use Cleo you'll have to play manually. She's all slide except before the 3rd drive skill you'll want to tap, and "if" her focus activates, slide the others quick and drop the fevertime. I say if, cause her focus has a fail rate. It can be cumbersome to use her.
Have people ever tested this advice? I have a +5 lv. 50 Cent.Vow and it seems to suck, the damage is never better than what is provided by even an off-element Atk/Crt carta.
Trial and error - best recommendation would be, find out for yourself. I don‘t invest ignition cores in Raids and have no ignited light attacker. That said, my Bastet tapping does higher dmg than my hildr(s). I wouldn‘t recommend investing in Bastet, since there are way stronger childs out there already
Add a screenshots with your light attackers, without it is difficult to help you.
