The player's Homing Pigeon increases their chance to keep Scrolls after using them.
Homing Pigeon adds a chance for the player to retain Scrolls after using one. Upon being activated, a "Homing Pigeon" message will appear, a bird will seem to fly into the player, and the player will keep whatever Scroll they most recently used. Initially, the player's save begins with zero Homing Pigeon, which cannot be increased through any Items during the run. Rather, Homing Pigeon can only be increased through Cat Plushies, Cat Shrines, Home Improvements, and Topiaries. Unless otherwise stated, all of the following increases are permanent and will affect all runs after being obtained. The specific sources can be seen below:
|Alien Ant Homing Pigeon Upgrade||+0.5% Homing Pigeon||1||Alien Ant|
|Chemist Ant Homing Pigeon Upgrade||+0.5% Homing Pigeon||1||Chemist Ant|
|Historian Ant Homing Pigeon Upgrade||+0.5% Homing Pigeon||1||Historian Ant|
|Sage Ant Homing Pigeon Upgrade||+0.5% Homing Pigeon||1||Sage Ant|
|Pigeon Topiary||+0.5% Homing Pigeon||1||Topiaries|
|Tuxedo Cat Plushie||+0.01% Homing Pigeon per Tuxedo Cat||0 to 200||Cat Plushies|
|Fireball Cat Plushie||+0.03% Homing Pigeon per Fireball Cat||0 to 200||Cat Plushies|
|Big Cat Statue Upgrade||+1% Homing Pigeon||1||Big Cat Statue|
|Summer Cat Modifier||+10% Homing Pigeon (Only when the given Shrine is enabled)||1||Summer Cat Shrine|
Note that for the above sources they are all additive, not multiplicative. For example, if the player already has Homing Pigeon at 2% and purchase the Chemist Ant Homing Pigeon Upgrade, they will have a new Homing Pigeon value of 2.5%.
