Rune
Once A Fool
Really? The cantrips alone are worth a feat, especially for melee attackers. Shield + Booming Blade + any other cantrip from the wizard list is a great set for any flavor of melee rogue and most other martials, too (not barbarians, obviously).I’d say instead that magic initiate and other older magic feats are weaker than average, and needed a boost or replacement.
Their stated logic is that you can go for a bigger punch the more specific a feat is, which is why, say, Drow High Magic can be so much more powerful in terms of spell levels.
All that said, I think the feat is cool as hell without a big AC boost, so I’ll review it again later.
Bless + Guidance + any other cantrip from the cleric list is also great for pretty much anybody.
