Reducing Armor Weight

[Matafuego]

A friends priest (which is now 81 years old and has a veeery low Str) can't almost carry his armor and holy symbol. Since he will continue adventuring (and is pretty high level)
Is there any spell that allows him to reduce the armor weight?
Or any items that increase his carrying capacity? (Besides from the Obvious Strength enhancers)

Thanks a lot

Well, you could ditch your armour and get mithral armour and shield, since mithral is lighter. Failing that, a miracle that could change the substance of your armour to mithral might work. Failing that, don't wear armour.
