Yep, they are. If they are part of a statblock, they are included. If I make a simulacrum of archmage, it has spellcasting. If I make a simulacrum of a PC with spellcasting (which includes prepared spells

) it has those.
And of course you are free to do so.
Correct. Once is all I need.
How about 100 of them? 10000 of them? Because that is what this loop can do.
Umm... I am not casting
wish, the simulacrums are.
Your world, do what you want... but none of that is RAW or addresses an abuse that is RAW-- which is sort of the point.
Luckily, of course there is. Which is why any sane DM (IMO) would not allow this RAW abuse.
Well, it isn't the job of the DM to kill off a PC (although some DMs do think that way... I don't, personally).
Great, the simulacrums are never casting this spell. They are casting
wish, which "duplicates" a spell of 8th level or lower, but doesn't actually
cast that spell.
Also great! I (the Wizard) have only cast it once.
I mean, I know there are hundreds of posts in this thread, but I'm basically just repeating points I've made before and I find it annoying, to be frank. If you want to take the time and read my responses upthread, you'll basically know how I am going to respond to future remarks about this sort of stuff. In short:
1. 2024 changed nothing about the RAW abuse chain for (practically) infinite simulacrums of my PC wizard once I hit 17th level.
2. The RAW abuse chain is:
a) I cast simulacrum to make a SIM of myself. Like myself, it has
wish prepared.
b) The SIM immediately casts its
wish to make a SIM of myself (not itself).
c) SIM2 now repeats, casing its
wish to make SIM of myself.
d) Repeat each new SIM of myself using its
wish to make another SIM of myself until I get tired of it.
At 600 SIMs per hour, that is thousands in a day, tens of thousands in a week, and hundreds of thousands in a month.
Nothing in the new version prevents it because:
1. the SIMs are not casting
simulacrum (they can't), but are casting
wish.
2. I have only cast the spell once.
So... hopefully that clears that up. You can of course rule or run a game however you want, but this is the RAW way the spells work. WotC could have prevented all of this in a few different ways, but big surprise... they didn't. Hopefully they will address this in the errata.
