In patch 7.9 the Remnant of the Watchers got its manareg reduced from 100% > 50% but it lookslike riot changed it [unintentionally?? maybe at the 8.2 rework] to 25%, which is odd as the frostfang has already 50% which makes sence as you buy a fariy charm to build it.

not sure if its a "bug" as the tear also loses manareg (for the manarefund passiv which could be arguably manareg repalcement) but here its not the case that you gain anything manarelated
