==Obtaining Units==
Units can be obtained via a variety of sources:
*Summoning via [[Banners]] (some units are in the general pool and others are limited to special banners)
*Transmuting via [[Unit Shards]] (generally not recommended for non-free units, although there are exceptions, see [[Unit Transmute Guide]])
*[[Free Units|Free]] from [[events]], [[story]] or other sources such as the [[Arena Coin Exchange]] (some are permanently available and some only during a limited time)
*[[Memento|Mementos]] - a small subset of units are only acquired this way
