Remove the targeting requirements of power word pain . pick a random person. Start each morning by casting power word pain on them, no matter where they are in the world or what theyre doing.
Control Flames
You choose nonmagical flame that you can see within range and that fits within a 5-foot cube. You affect it in one of the following ways:
You instantaneously extinguish the flames within the cube
I turn off the sun
And dumping the sun’s volume of water on it won’t put it out. If anything all that extra hydrogen will make it “burn” hotter and longer.
" Create Water" cantrip.
Ignore the limit of 2 gallons per level.
The cleric/druid can now summon oceans worth of water, at will.
Combine with the “Shape Water” cantrip, and your wizard and cleric are now an unstoppable force at level 1. Especially if you ignore the limit of abilities the wizard can manage at a time.
You could start reviving unwilling souls (theurgy school).
You could also remove the HP requirement from power word kill to kill any creature instantly.
Disintegrate without having to fail the dex save is also pretty funny.
True Strike
You extend your hand and point a finger at a target in range. Your magic grants you a brief insight into the target’s defenses. On your next turn you gain advantage on your first attack roll against the target provided that this spell hasn’t ended.
Literally the only way to make the worst spell worse
