Clockworks are constructs created through a fusion of magic and technology. They have the following traits unless otherwise noted.

• Winding (Ex) Clockwork constructs must be wound with special keys in order to function. As a general rule, a fully wound clockwork can remain active for 1 day per Hit Die, but shorter or longer durations are possible.
• Vulnerable to Electricity: Clockwork constructs take 150% as much damage as normal from electricity attacks.
• Swift Reactions (Ex) Clockwork constructs generally react much more swiftly than other constructs. They gain Improved Initiative and Lightning Reflexes as bonus feats, and gain a +2 dodge bonus to AC.
• Difficult to Create (Ex) The time and gp cost required to create a clockwork is 150% of normal. Construction requirements in individual clockwork monster entries are already increased.
