Default says:
Able to damage constructs while using the turn ability. Constructs are not turned, but instead damaged 1d3 per Turn level, e.g. 1d3 to 40d3, to the limit of the hit dice turned. The damage type is magical.

A side note, the icon on my toon is the turn undead one and the description is a bit messy. But the most disturbing thing: when activated, it's killing undeads ! So could someone please clarify the proper mechanism ? Appreciate that.
