Corridor of Love is the 4th map in Super Dimensional Etna, the 1st episode of Etna Mode.
Strategy[]
In Etna Mode, this map's strategy changes drastically. There are swarms of four Ghosts on both stairs near the Base Panel, with Archers stationed on top of the set in front of the Base Panel that will not act unless something moves within their attack range. There's also a Ronin with a Spear stationed all the way on the map's left corner that will move after a turn has passed, whether you are ready or not. Lastly, there are two Geo Symbols with both Damage and Recovery 20% effects respectively. Have a non-attacking character throw the Recovery symbol down first, so Etna's troops can heal after eating the many attacks of the Ghosts. Defeat the Ghosts on both flights of stairs first. Then have two powerful characters (With at least more than 22 HP) fight off the Archers. The Ronin has most likely advanced near your troops this turn, so throw the Recovery symbol out, and throw the Damage symbol in, the move all characters out. The Ronin's movement is so-so, at best, so if her way is blocked, then she will be forced to attack from the Damage effect area. Block her for a few turns, with Etna and her troops attacking. Eventually, the Ronin will either succumb to the characters' power or the Damage 20% Effect.
