Lugh have 20% C frame def down, 400k nuke which turn into 800k after burst, and her 3rd skill which make her broken is reset her nuke with the cost of 15%...20% of her max HP, and you can use it every turn, I know, it crazy, the dev are on crack when making light hime so get use to it already, her passive is receive double the heal from any source to cover her suicidal 3rd skill. Iris have a 1m nuke 6t CD, a 30% light resist down (RIP Tsukuyomi no one will remember you) and a every turn spam gacha game on her 3rd skill which give her a random buff card ( 6 type of buff like assault, element atk, abi dmg, DA, TA,etc and a rainbow card) and 10% BG; when she burst all her buff card she hold activate for 3t I think, those buff are really strong and if you have rainbow card you get all 6 type of buff. Those 2 are future hime, about take you can look her up on wiki but tbh I don’t think she worth a MT
