After a unit is unlocked, you can summon one additional copy of the unit by converting 100 of its Fragments.
To summon a 2nd copy of the unit, you need to have 100 Fragments of said unit and a copy of it. You can also get the 2nd copy through the Summoning Pit, at the Training Camp, or by purchasing it at the Shop or from an offer.
How can I summon 2nd copy of a unit?
