The description of the warlock's Gift of the Ever-Living Ones eldritch invocation (XGtE, p. 57) says:
Prerequisite: Pact of the Chain feature
Whenever you regain hit points while your familiar is within 100 feet of you, treat any dice rolled to determine the hit points you regain as having rolled their maximum value for you.
I'm trying to plan out my Warlock build. I'm curious if the invocation Gift of the Ever-Living Ones allows you to take the max die roll for potions and healing spells cast upon you by others.
The wording seems a bit vague to me, and so I'm a little confused.
