Magic Eight Ball
Well firstly you get to choose a patron! Like a demon, fey, or cthulu, as well as some other fun choices. They give you your power.
They are different from the other spellcasters in that they don't have as many spells. They might consider it a weakness. But you know better.
You see, while you may not have many spell slots, you always get to cast your spells at their max level availabl, meaning your always slinging them about at full power.
Even better! You recover your spell slots after just a short rest. Used all your spell slots? Take a fifteen minute breather and your good to go while the wizard and sorcerer are helplessly watching and out of spell bullets until its bedtime.
And even better than that! You can have eldritch blast! A very fun cantrip thats basically like having a guns in your hands. Essentially shooting laser blasts left and right. Growing to firing multiple at a time.
To add onto that! You get invocations! Which are like special feats that apply to you and your spells. There are some pretty fun and useful ones.
Then comes the subclasses!
You got the pact of the chain! Giving you a pretty sweet and special familiar. much utility. And can even pick ones that you normally could get ahold of. Like a psuedo-dragon.
There is pact of the tome. You get a magic book that lets you record spells as rituals for you to use anytime. And is the subclass to focus on spellcasting. Not to be underestimated.
And there is pact of the hexblade! You get a special weapon bound to you, and can use it very well. It can do some pretty great things. A surprisingly good combatant.
There are likely others too in unearthed arcana content.
