I came upon an orb processed by Olhydra. It is now my patron, of sorts. I am a Warlock. I am now no longer a Warlock, I am now a One Eyed Shiver (on the inside, mostly).

My spells are: Mending, Resistance, shape water, create or destroy water, cure wounds, fog cloud, thunderwave, darkvision, hold person, protection from poison, call lightning, sleet storm, tidal wave.

Along with all the other spells the One Eyed Shiver has.

It says I'm a 5th level spellcaster.

How do I make this work? This is my first DnD campaign and I am confused. How do I level up? Can someone help me come up with a sheet? I can't get dndbeyond to work with this setup. What would this look like at level 5?

Any help would be appreciated.

Thank you!
