Lock

When in the Tributary tab, you have the option to Lock any of your Occupied Planets. Locking a planet reduces the Revolt Percentage of the planet by an ammount dependant on the type and ammount of lock.

There are three ways to lock a planet. When you first occupy a planet, posting it will give you 1% lock for each person who clicks your post. Otherwise, you can Turn-Lock by 10, 20, 30, 40, or 50 turns. This not only reduces your normal Revolt rate, but also causes any attackers to pay more turns to take away your planet. For every 10 tuns spent to lock, your revolt rate is reduced by 12 hours (10 turns per 12 hours).

The last way to lock is a Premium-Lock. Premium Locking makes your planet completly untouchable and unrevoltable for as long as it is premium-locked. The cost for premium locking changes for each planet, but is reliant upon the ammount of tributes, strength of tributes, length of lock and creatures that tribute. You can premium-lock for 3, 5, 7, 11 or 15 days.
