Can you clear LFR HoF and enter Terrace?

[Abyssion]

Or you need to clear it on normal?

[Lockula]

It depends if I get a group that passes Garalon.

I believe you need to clear it on Normal Mode first. I can't confirm that though as I have not done it myself personally.

Well since the second half of HoF LFR is not open till next week I guess we won't know till then, although I should imagine that you can since there's no separate achievements for LFR and normal.
