New Invocations Thread

After the amazing developments we saw in Tales of the Valiant: Wizards has alot of inspiration for new invocations that actually bridge the gap between the mid spellcasting of Warlocks and "full" casters.  Since Ravenloft (sigh) had ZERO invocations for arguably, DnD's most spooky character, I'm hoping that the two new magic books (reference and adventure) due out later this year will actually add invocations to the game. 

Personally one idea I'm hoping to see is spellcasting invocations to smooth out the casting curve: 

- invocations that allow you to use a spell or spell-like power a number of times per day (doesn't have to be infinite).

- invocations that allow a lock to cast a spell (/cough polymorph) once per day. 

- invocations that provide multiple spells, once per day - just look to Baldur's Gate 3. 

... any other ideas? Wizards, please take note and thank you. 

they will probably rehash old invocations first, while we may eventually get truly new ones I expect it will be a while. 

I’d like to see them do this for level 6 and up spells since there’s no other way for warlocks to get them, unlike polymorph that could be on a subclass spell list. Make them a level 12 or 15 requirement or something.
