Cannot have Red Heart containers. Any item that gives Red Heart containers will grant a Soul Heart instead.
By default, Andromeda has passive tear effects of Tiny Planet and Anti-Gravity with the only difference being that tears can be accelerated or slowed down depending on the movement while shooting.
Andromeda is unable to find any Zodiac items outside of Abandoned Planetariums.
Getting 4 Zodiac or Planetarium items as Andromeda (three as any other character) will also grant the Spode transformation.
Andromeda starts with a pocket active Gravity Shift, which besides its normal use of stopping tears and projectiles, has special effects on Andromeda depending on the room it was used in:
✦ Using it in a Treasure Room before picking up an item will activate Glowing Hourglass effect and transform the room into an Abandoned Planetarium instead. This will also increase the Planetarium chance.
✦ Using it in a Planetarium before picking up an item will transform the Planetarium item into 4 random Treasure Room items to choose from, give a random Lemegeton wisp, and reduce the room's gravity.
✦ Using it in a Shop before buying anything will remove everything the Shop has to offer and spawn a random Treasure Room item on sale for 30¢.
✦ Using it in a Devil Room before buying anything will transform every Devil Deal into runes for sale, surrounded by spikes.
✦ Using it in an Angel Room before picking up anything will transform every item into random trinkets to choose from.
✦ Using it in a Secret Room will transform every item into 5 normal wisps and pickups into normal wisps with 50% chance, no matter if anything was picked up before or not.
✦ Using it in a Super Secret Room has the same effect as Secret Rooms, but wisps will be random.
