Good Astral Self Monklock Spells

[ChaseC311]

Im currently playing an Astral Self Monk Multiclassed with a Great Old One Warlock, what spells would be best for the Multiclass? Im currently playing with 2 levels in Warlock, 3 in Monk, meaning I have 2 Cantrips, 3 Spells, and 2 1st Level Spell Slots. My character currently has an ability where he knows the unseen servant spell (not counting against spells known) and can cast Haste Or Slow Once Per Long Rest (Also Not Counting Against Spells Known) in case that matters

Hex is good with monks ability to flurry. Armor of Agathys also works well with characters that may get hit or tend to be a bit squishy. Obviously darkness is good for when you gain the ability to see through darkness.
