Is this a "That Guy" Thing to do?

I agree for the most part, but as my character was already studying hybridization and, as I said, was in the market for a new body, I feel like it's kind of given that he comes up with something relating to the 2 when given Wish.

I don't see it that way.

Coming up with that plan takes INT. Going with the plan, even considering that all your enemies so far had bite-damage resistance and also had opportunity to kill someone for good -even though they're supposed to be immortal- that would be WIS.

That's the way I see it.

Oh, and by the way, that second part, about taking WIS... I meant that it would take negative WIS to go with a plan that has serious flaws: because you are not very wise if you do so.

He's a 3.5 DM in 2016, he deserved it 8 years ago.

It's 5e. Crossbreeding system was adapted.

I gave a player a deck of many things once. He used it at the final fight of the campaign and killed the most powerful being in the universe with a kick to the balls.

If you're already homebrewing shit, WHO GIVES A SINGLE FUCK at this point.

If this is something your character would want to do, then sure, go fucking nuts, but if you're doing it for "YAY BIGGER NUMBERS" then what are you doing with your life, seriously.

yes
The idea itself is hella cool, I give you that, but why would you purposefully ruin your entire game?
How about using those wishes for something fun instead?

>wish operates like 3.5
>create life spell is a 3.5 spell
>soul transfer is a 3.5 spell
Don't lie, OP.

If you tried this in my game in 5e, I'd allow it:
>you: I wish for my next wish to be granted to my expectation
>me: OK, granted... *roll dice* you lose the ability to ever cast a wish again and take 9d10 psychic damage that cannot be reduced. And your strength drops to 2 for... *rolls dice* 5 days.

That's hardly a clever backfire.
