Notes
- This feat is one of the few ways to gain Advantage on all types of saving throws. Player characters in honour mode may benefit from this feat in situations where failure has particularly unfortunate results or, conversely, success is deemed essential.
Bugs
- Lucky grants a toggleable passive by the same name which, when toggled on, provides Advantage on the character's next Ability Check. Due to the way this passive is granted, it defaults to "off" and cannot be toggled "on" the very first time it is acquired until after the character has first made an ability check, has used a reaction, has used a short rest, or has used a long rest.
