Aegis

It halves damage sustained when the peasant's health is below 25%. It does not reduce damage from TRANSMUT3 and levers in Sacrifice Rooms.

Trivia

 * The Aegis could be a reference to Greek mythology, which the shield made from a Goat Skin to protect Amalthea.
 * The person that The Knight Toadvine saved was most likely Bathcat; that could be why Toadvine dislikes Bathcat and why Bathcat always seems so shy.
