Guardian Tales Co-op lv78 dungeon using RUE with Marianne EX! 守望傳說共鬥, 用瑪麗安專武攻略78等副本!

Wanted to do lv 80 dungeon but my Guardian Base level have been stuck in lv175 for weeks (poor me with not enough unique EX weapons...), will update lv 80 in near future hopefully.
其實想挑戰80+的副本,但是我的守護者基地卡在175等好幾週了... (非洲酋長沒 有抽到專武解開176等...), 希望日後還是能更新80級共鬥副本
