So I have 396 medium refines and 234 advance refines. If the lucky board has medium refines to claim I can get another 200 from there.

My current refine levels on my equipment is everything is level 5 except for 1 piece which is at level 6. I understand I need to go up 2 levels in refines to make use of the event properly but if I do that the level 5 refines become 7 and the wish bonuses will be wasted if I don't have enough advance refines to push them to 8.

What's my best course of action here? Just push to level 8 whatever I can and go for level 7 with whatever is left? Btw I know 600 medium refines aren't that much considering the levels my gear currently has, it's probly going to be enough for like 4 or so equips.
