Can you apply the same metamagic feat twice?

The metamagic feat that really breaks when you apply it multiple times is Extend.

Take a high level cleric (i.e. 20th). He has +5 armour and shield that last for 120 hours. +5 weapons that last for 100 hours. For the next 3-4 days he still has the benefit of all of those spells without it costing him the spell slots. That's pretty damn impressive.

Well, I've seen people stack Persistent and Extend to achieve similar effects.

It's worth noting that under the 3.5 rules, empower can not be used with the stat buffing spells.

Yeah, they triple fixed that. Nixed duration, randomness, and stacking empowers. With that and some other fixes, I was tempted to believe someone at WoTC was following my epic cleric around...

I definitely liked stat spells with 4 empowers on them.

Another great abuse of the multiple-metamagic idea on 3.0 rules was multiple-empowered buff spells.

An empowered, empowered, empowered bull's strength? Not too shabby, considering you could potentially add like 14 to your Str... This is another case where they decided to "fix everything" instead of just one thing (limiting the buff spells to static, non-empower-able numbers).
