I never had any repercussion using Guidance. And I'm using it constantly. So I'm a bit perplexe here.
Same here. I’ve never had anyone react badly to Guidance or any other spell that boosts my character rather than affects the NPC directly.
I think the game gives you fair warning about Friends and Charm Person, and I’ve not used them on NPCs not prone to hostility as a result. So I’m not sure whether Friends is always noticed by NPCs or only sometimes, eg if they failed an insight check. I would prefer the latter to actually make the cantrip more usable, though from the 5e rules Melivy quotes it sounds as though the NPC would always realise they’d be influenced so that’s fair enough. Charm is stronger so it makes sense they’d notice that.
And I definitely don’t think NPCs should turn hostile if they notice the spell, unless they’re on the edge of doing so anyway. Rather, an attitude reduction and refusing to speak further with the party would make more sense in most contexts.
