It's cool that Vestige warlock can get Spirit Guardians via War domain spells, and the Vestige itself seems pretty big on HP. Can take pact of the blade to be a melee bruiser, with the vestige backing you up from range. I haven't checked to see if there is any other way to get both SG and Extra Attack by level 5 using only 2024 core-and-expanded rules yet, but this is an exciting development!
