I'm not asking for proof, this isn't a science, its a demonstration. Sure, you don't have to participate, but I'm curious to know what you'd pick. Even if it doesn't wholly prove my point, it might at least show where I'm coming from.I don't need to engage in someone else's cherry picked whiteroom combat scenario to "prove" wizards are strong and flexible - because it is true.
My point isn't that casters are weak, either, its that they must be careful or else they could easily be ineffective in practice.
Interesting. Which creatures would you change into, if you don't mind?Therefore if I was alone I would go with a self buff like shapechange.
Edit: Actually, this spell is off-limits because of the single restriction of "no costly spell components." You actually could have done it with Wish if it was 8th-level or lower, but since it requires a spell component, its in the realm of "DM fiat."
