#comprehend languages

Bill Seacaster would 100% offer Adaine drugs to “steady her nerves during battle”. Like, fantasy pirate snuff-Valium.

Adaine has a panic attack trying to figure out a polite way to decline the very enthusiastic offer of drugs from the most terrifying man in existence. 

Fabian, who thought his dad was going to stop offering his friends drugs, is mortified.

Kristen has to physically stop Fig from going for the Valium-snuff. 

Comprehend Languages is a level 1 Divination Spell for Bard Sorcerer Warlock and Wizard. Casting Time is 1 action or it can be cast as a Ritual Range is Self Requires a Verbal and Somatic Component and spell ingredient is a pinch of soot and salt and Duration is 1 hour.

Ooo, variety!

Burning Hands: Though the range is ludicrously poor, 3d6 (average 10.5) fire damage to everyone approaching you is a great deterrent in realistic situations. Since it's fire and specifically ignites flammable objects, you can use it for utility. Since this is the only attack spell mentioned, I'm betting you're relying on cantrips (i.e., infinite use spells) as your primary weapons.

Charm Person: This is another spell which, if applied correctly, can solve encounters (in this case, both combat and social ones). I picked it as my only spell in a Basic D&D game that's currently on pause (I'm a first-level elf; I have one spell per day) for exactly that reason -- and it worked. The duration isn't nearly as long in 5e (because BD&D's is broken; the ogre I charmed is my long-term mind slave now), but it's long enough. Best used against stupid things, which abound.
