Now the next 3 banshees you might miss altogether. They are located in the graveyard to the left of the map.
Send Thalya to it and after the narrator says some dialogue she'll resurrect the remaining 3 banshees from their graves, giving you 5 total and the achievement.

This is done in the "The Titan of Alphaas" level. Banshees are melee Undead units which do area of effect damage and has a slow-enemy area effect but tend to be weak. Since this level has no dungeon, you'll need to find Banshees in the level. In this level some Heroes have been contaminated and once killed will convert to Undead. Some of these are Banshees. Make sure to keep them alive as they're in short supply.
At the 1st one-third of the level you'll encounter small villages and groups of Heroes, as well as several trapped Undead. Destroy everything and you'll get 3 Banshees. At the western end of the map (denoted by a magic book icon) is a graveyard.
Visit it and the Narrator is say something, while Thalya will make a grand speech. Shortly after, 2 more Banshees will spawn. If you kept the 1st 3 Banshees alive, the trophy will pop once these 2 Banshees spawn.
The trophy will pop once you find 5 Banshees.
