Forum:No option to envole my 5 Star units

Hi guys i just Cant envolve my 5 star units. They are all 5 star and max lvl 80: Lava, rickel, 2 x eltri, amy, edea, rameldria, eze, lance, malnaplis.

I am lvl 101 and i Play on android.

Either i Cant See the pot dungeon on tuesdays or totem lvl 4 dungeon.

And i habe never Seen a 6 Star units in Arena or friends

What's wrong?
