Two new Eldrich invocations were added in the Villainous UA part 2. One of them, called "Elemental Transmutation" is actually quite useful. It says

"Choose a damage type: Acid, Cold, Fire, Lightning, or Thunder. Once per turn, whenever you deal damage of any of the above types, you can deal the chosen damage type instead"

This REALLY helps subclasses like pact of the fiend/celestial where you get fireball/firewall; for a single invocation you can make them "acidball and/or acidwall"; which is almost never resisted; giving these spells real staying/lasting power into tier 4.
