Hey guys!

Only difference is +2 does interrupt and Y does slow

Slow is an awesome debuff but nowadays everyone is immune so it could be useless mostly, so I'd recommend +2 in most cases

Probably +2 better most of the time

The +2 if you can trigger the chase at least twice per mystery

Y is definitely a lot stronger IF you can trigger it with your team

Personally reflecting all debuffs gets a win for me, that stuff is much better than debuff immunity although you will still take damage as opposed to using dodges

For breakthrough priority I would say:

Passive 2 > Chase > Mystery > Passive 1 > Standard

1. Fire Main

2. Fire Main 2

3. Water Main
