Yea, I think that event girls should have a solid shot at clearing equipment extreme. I scraped by with Cepha Lanthera (11640 HP/2550 atk/2990 def), Geranium (18456 hp/2273 atk/3031 def), Southern Cross (16896 hp/1923 atk/3217 def), Robinia (13610 hp/2293 atk/2949 def), and Lycoris (21096 hp/2569 atk/3155 def). The Lycoris had less impact than expected due to rolling poorly with skills.
