Now just recently I have had a group of friends get into D&D 5e and I ran into an issue with the Warlock class Spell Slots.
Cantrips: a spell that can be cast at will, without using a spell slot and without being prepared in advance. Repeated practice has fixed the spell in the caster’s mind and infused the caster with the magic needed to produce the effect over and over. Pretty obvious. You know as many as your class level tells you you can know.
Spells Known: How many spells your character can know excluding cantrips. My only question for this is if old known spells can be switched out for new higher level ones?
Spell Slots: the slot leveling I understand, but the whole basis behind it is what confuses me. Are spell slots their own separate choice of spell similar to how cantrips are separate from your spells known? Do you choose spells to know and out of the known spells you prepare ones to slots and they are cast at the slot level, not the normal level? When consumed for casting a spell, are they consumed on known spells and slot spells or just slot spells?
I just need some explanation. I’m a bit more of a visual learner so instead of someone just explaining what a spell slot is, please add a couple examples. (Ex. Warlock at 1st-9th level and a small scenario or two in which they would use a spell they know and a spell slot.) I want to know their spellcasting and how they progress level wise as much as I can.
