D&D 5E Arcane Trickster with Wizard Splash

[Roman Ryder]

I'm thinking about taking a level of wizard on my arcane trickster.

Will that allow me to copy and prepare spells up to my arcane trickster level of spell slots? For instance, can a rogue 13/wizard 1 copy a fireball spell into his spellbook and prepare it or would it be limited to copying and preparing level 1 spells?

Level 1 spells only, as if you were a 1st level wizard.

 

[Charlaquin]

From the basic rules:

You determine what Spells you know and can prepare for each class individually, as if you were a single-classed member of that class. If you are a Ranger 4/wizard 3, for example, you know three 1st-level Ranger Spells based on your levels in the Ranger class. As 3rd-level Wizard, you know three Wizard Cantrips, and Your Spellbook contains ten Wizard Spells, two of which (the two you gained when you reached 3rd level as a wizard) can be 2nd-level Spells. If your Intelligence is 16, you can prepare six Wizard Spells from Your Spellbook.

Each spell you know and prepare is associated with one of your Classes, and you use the spellcasting ability of that class when you cast the spell. Similarly, a spellcasting focus, such as a holy Symbol, can be used only for the Spells from the class associated with that focus.

I guess my confusion was thinking about the class of spells...wizard...vs arcane trickster being a different casting class than wizard. Thanks!

Hear's an interesting idea! Each time I level, I can replace a spell. I could replace all of the AT level 1 spells with level 2 spells and just use wizard for my selection of level 1 spells.

You can totally do that. You can also use your wizard spells to pick up spells from schools you'd otherwise be unable to get beyond the few choices at certain levels.

Agreed, but are level 1 spells really that important at the 3rd tier? Are they worth the shenanigans and the delay of acquisition of 8-9 level spells?

He is primarily an arcane trickster so the 8-9 level spells were never in the picture.

Sorry, got confused with the Bard MC topic next door.

Still, there are a lot of goodies at the higher rouge levels, is "optimizing" 1st level spells (whole 6 of them per day) worth postponing acquisition of said goodies and completely foregoing the capstone?


Added: if we are talking of a wizard dip, I would consider at least two levels to get the School benefits.
