For example, a key wielder cannot lower the cultivation requirements of a gates before quickly raising it. However, a key wielder can arbitrarily increase the cultivation requirement whenever they want. Such an ability for a sneak attack would be devastating. This was like what Dyon did with Thadius during his meeting with the Uidah.
Had God Goldeen raised the limit to the celestial realm, they might have been able to conquer the tower before the Flaming Lily Sect even responded.
The restriction to these raising and lowering abilities was simple.
For one, this ability only worked in one universe. It couldn't be used on gates outside the universe that was home to their Epistemic Tower. If they wanted to change the cultivation threshold of a gate outside this region, they'd have to do it the conventional way and conquer all of the towers within.
