Unlimited power with SRD only materials

[The Glyphstone]

I'm not adding additional text, I'm acting within the boundaries of the rule. Namely the non-existent ones.

It's RAW in that the rule is there and it does allow me to do that.

Repeat - show that the rule 'Wish ignores item creation prerequisites' is in there. The XP Costs section gives an exception to the XP Costs of creating an item - specifically, that it costs the normal amount plus 5,000. Non-XP-related prerequisites would not belong in a section titled 'XP Costs', so claiming their absence is justification for not needing them is false.

If it worked the way you say then pun-pun would have to add abilities that exist rather than making them up. Which has been proven to not be the case.

Except that is how Pun-Pun works, the official version. The alternate version that outright makes up abilities is blatantly noted as going beyond the RAW.
