Fire Emblem Echoes: Shadows of Valentia - Unused Skills [Hack]

In this video, I show off several skills and combat arts that exist in the game data, but are not accessible via gameplay. Note 1: Multiple hacks were used to make it easier to record footage. For example, modification of enemy stats, items and skill costs. Note 2: A couple of skills do not have names and/or descriptions, so I added them myself for illustrative purposes. (Speculum is not one of these.) Note 3: There is also a Wrath skill that doesn't seem to do anything. Its description claims that it boosts critical when under half HP.
