Munchkins and Dragons/Miscellaneous/TAINLATDID&D

Welcome.
This is a list, very similar to the list of things Mr. Welch is no longer allowed to do in RPGs.
All of these things have happened within the M&D universe, in games compaigns to the one that the story takes place in. (Though said campaigns take place in a different universe, so you won't be seeing Avia mention them. In fact, not all of them were even with the same group of players.. But they all were things Alex did.)
If you didn't already know, Alex is Avia's player.
So, here goes nothing.
#[5e] No, I can't wish for more wishes.
#Can't bring a boss back to life to kill it again for more EXP.
#[BECMI] No, I cannot just sell treasure and buy it again for free EXP. There's a reason why EXP is not awarded until the end of an adventure.
#[4e] No more playing this edition. It's broken.
#[3.5e] Can't make a custom spell that removes the need for spell preparation:That's what the Sorcerer class is for.
#Can't make Charisma my dump stat, then ask them to do the opposite of what I want:Bad Charisma means bad Bluff, after all.
#If I fail my Sense Motive check, can't give a hint to the party that I failed.
#In fact, this applies to all Wisdom checks.
#And Intellegence checks.
#[3.5e] No, I can't wish to automatically Ascend to a Rank 20 Deity.
#If the party rushes into a fight with a plan that will fail, can't shout "LEEEEROY! JENKINS!"
