Singing Steel trait

Effects
This lustrous golden metal emits beautiful bell-like tones when struck. An alloy of gold and mithral, singing steel was originally created by the elves.

Most armor made of singing steel is treated as one category lighter (heavy armors are treated as medium, and medium armors are treated as light, but light armors are still treated as light). The armor or shield's arcane spell failure chance is reduced by 5%, its maximum Dexterity bonus is increased by 1, and its armor check penalty is reduced by 1 (to a minimum of 0).

The wielder or wearer can strike the singing steel as part of beginning a bardic performance. If the wielder can normally start a bardic performance as a standard action, he can do so as a move action instead. If the wielder can normally start a bardic performance as a move action, he can do so as a swift action instead. If the wielder can normally start a bardic performance as a swift action, he can do so as a free action instead.
