The other night one of my fellow gamers exclaimed, after my 6th fireball, "how many fireballs can you cast?". My response, "lots".
My question is around casting lower level spells at higher levels. Is this the correct way to think about it?
Example:
My first fireballs of the day are normally maximized cast at a lvl 5 slot. (Using Magical Lineage trait) So I tick off a lvl 5 spell used every time.
Currently I can cast 7 lvl 5 spells per day. So after 7 maximized fireballs I can no longer cast anything from a level 5 spot. But I still have all my lvl 3 slots open.
So effectively, not saying I would actually do this, I can use all my spells per day from 3rd level to 7th level on just fireballs. Is this correct or am I overlooking something?
If I wasn't applying metamagic I can still cast a lower level spell at a higher slot correct? If I am out of 3rd levels I can just cast fireball from 4th level?
