A Title Much Cooler Than Anything on the Old Site
The player and I talked about it and, in general, where I don't already have home rules, I try to run the game RAW. I was initially inclined to rule that the wizard who cast the simulacrum still had to roll the 33% failure, but "you" in spell descriptions obviously is meant to be the caster, so I allowed it. It is already a high-level magic, gonzo campaign. I could see home ruling wish to work like this though. Where the 33% risk was a risk to the wizard who cast simulacrum. But if I'm going to go down this route, I might as well stick with a lower magic system or homebrew the spells lists in 5e. With high level teleportation, polymorph, time stop, scrying, summoning, the ability to create golems, etc., the simulacrum has not really stood out at that huge of an issue.I was a bit off on the wish consequences (later post) but, yeah, having simulacrum essentially be a wish proxy is both a great idea - and seems like a total abuse.
I guess where it could get broken is if the simulacrum cast a wish wishing that he would not be destroyed if the wizard who created him cast the simulacrum spell again. But it is well within my judgement as DM, based on how the wish spell's description is written, to not allow that. I haven't had to rule on this yet, as the player hasn't tried it, but my ruling would be that sim 1 would now be a fully independent entity. A clone of the original wizard but with a mind and personality of his own and would be driven to destroy the original wizard and any other sims/clones. It fits within my campaign and seems well within RAW.
