Can you stack "charm" spells?

[lusi]

Hello there,

I was expecting to do a very convincing seductress, skilled in every social interactions including intimidation ect..

My question is : is it possilbe to stack charm spells, "charm person" "friends" and "fey presence" together for even more chance of success ?
Seems they all give you "advantage" aka "roll 2 dice" and that's all, so it's completely useless stacking them right? Or there is something more?

I also noticed than "fey presence" seems the only one charm spell where the npc won't blame you for being charmed afterwards so it's same effect than other spell without any negative consequences?

Thanks for reading me and answer me, have good games!

Charm spells do not "stack", as advantage does not stack, however certain charm spells are better for certain situations, so there may be reasons to cast 2 different charm spell in other situations. Most charm spells (mind altering effects in general) will have some kind of repercussion on wearing off, because if someone thinks you are close friends, and the spell wears off suddenly you are a stranger again and they can realise you used magic to make them more amenable
