No ability use stoppage until level 100

[Stardrinker]

There's nothing stopping Napalm, Cripple Monster or Cluster Bomb from being used on level 99. Nuke has a check for <= 97, which is still probably too close, and I wouldn't even use Napalm at all due to its DoT nature.

It's entirely possible that most of the nuking going on is from normal people using the script.
