Lamps and Harps

Are Lamps and Harps also obtainable in any story dungeons ?
Or only in the special missions ?

If yes in which dungeons ?

I guess in the online storyline, chapter 5 and 6. I got some from these :slight_smile:

Lamps are in 5 & 6 dungeons, harps are in chp 4 dungeons.

Thank you very much !
