Phoenix Pyre, ARGH!

Reinvigoration items stack if you use multiple types of item. For example, amulet of resilience + girdle of strength will stack, amulet of resilience + amulet of resilience will not. Again, I wouldn't try it with a flame tongue, they're too vulnerable and not enough reinvigoration. But if you're going to summon a magma dragon, you could do worse than giving it an amulet of resilience + girdle of strength, script it to cast summon earthpower, phoenix pyre and fire shield.
