Glowing Hourglass#422

This article is about the glowing hourglass. For the normal version of this item, see The Hourglass. Glowing Hourglass is an activated item added in The Binding of Isaac: Afterbirth.

• Prior to Repentance V1.7.9a, Glowing Hourglass was called "Glowing Hour Glass".

Bug! For some reason, having Error trinket with you will make your familiars "respawn" each time you use Glowing Hourglass, which leads for some interesting interactions. For example, Buddy in a Box and 7 Seals will change their forms each time leap, and the Star of Bethlehem will change its position to the room where you ended up after the time leap, allowing you to move it where you want it to be. Bug! Going back in time will add one more copy of each familiar that were created by Monster Manual for the duration of the room you ended up in, regardless if you have it with you or not. Exiting this room and using Glowing Hourglass again will add another copy for each time leap you do, it will still last untill you will exit that room and will be reset afterwards. Bug! Going back to the starting room will undo some map-revealing effects, such as The Compass. Bug! If a new game is started and Eden begins with this item, using it in the first room will remove Eden's starting items. Bug! Using the reworked Glowing Hourglass in the starting room in Greed mode or Greedier mode will result in a game crash.
