Weapon choice

Played back into a Genshin account with arlechinno, only at 30 but already have a decent set for her, sadly the only available weapon is favinous lance. With 24 star glitter, should I get royal spear on her, as it gives decent atk, wait for black cliff pole, white tassel as everyone suggests(r5) or get battle pass to get deathmatch? Thanks for the help!:)
