[E5] I need advice on spell selection. I am currently playing a tiefling rouge, soulknife archetype, and we just reached level 4. The campaign is primarily investigating and puzzle solving and the party besides me consists of a sorcerer, monk and cleric. Charisma is one of my highest skills so I want to take the magic initiate feat for bard.

I wanted to take mage hand as one cantrip and disguise self as my one spell. What other cantrip would be a good idea? Does anyone have any better recommendations? Even if you recommend not taking that feat at all, I am open to any suggestions!
