What abilities allow me to reroll or replace die rolls?

I am building a “lucky wizard” for my newest campaign.

The concept is to use abilities and features that allow me to reroll (or replace rolls) attacks, abilities, and/or saving throws (such as the Lucky feat). I’m not interested in abilities that allow rerolls on allies’ or enemies’ rolls.

My search so far has yielded a few options, but I am unsure if I’ve missed any.

  • Portent (Divination Wizard)
  • The Lucky feat
  • Lucky (Halfling racial trait)

Are there others?
