I just managed to get a copy of PHBII through alternative means and I noticed that the 4th level celerity spell allows the mage to get an additional standard action. For a level 20 mage, this gets unbelievably broken. If the mage were to put this spell in a contingency and states for it to activate whenever someone does anything hostile to him, then he automatically gets the first initiative. There goes any point to taking the improved initiative line of feats.
If the mage subsequently uses timestop, then he has enough time to screw someone over via damage over time spells, (like cloudkill) cage him, and then dimension door somewhere else until he can recover. So the question is, should the conditions in the contingency spell be considered valid (since celerity itself is an immediate action and cannot be used until the second round of combat when everyone is not flat footed)? Or should celerity even be able to be put in a contingency?
