Read minds? I'll pass. Too much drama/distractions to deal with.
augury (hello, stock market day trading)
I think its not exactly beneficial for trading, if the results gives you both good and bad omen, and you just have one shot at it throughout the day. And even if it gives you good omen, it will not tell you how much will be your gain.
Anyway
Lesser Restoration is a top pick here, its really nice and noble to heal others especially to people you care about. But I'm thinking more on its implications that in the long run I might feel too pressured to choose whom to heal (especially if people for healing were supposed to die that day - I would need to pick one and can result to vengeance/threats from other people not healed), in order to make money out of it one is expected to be eventually famous about it (publicly or in black markets) which can hinder my day to day living and could potentially endanger my life.
I prefer spells that I can use to my advantage in secret so
Invisibility and
Sleep came to mind however I'm also considering the duration of the spells. The duration of these spells are good in DnD combat/roleplay but not enough in real life (1 hour or 1 minute duration only per day - not enough for me). A manipulative bit part of me is also considering
Suggestion (1 person, 8hrs a day) and work my way to the top and can be a defensive spell too. Assuming that when the spell ends the person will not know he was charmed the whole time.
Given all of these that I prefer spells that I can secretly use in my advantage and the duration of the spells my final pick were these 3 Cantrips (at-will):
*
Minor Illusion - illusion or sound
*
Mending - handy and profitable too (contact me if you want your cracked/broken phone, laptop, engine etc. repaired)
*
Eldritch Blast - for defensive purposes
Each to his own, these are just my preferences.
