What is bounty and how do I use it?

Bounties can be raised from the Hall of Heroes. It is an alliance building so your alliance must be of a certain level (sorry I forgot) to build one. If your alliance already has one then you're good to go.

Bounties require Hero Coins to raise. Hero coins can be gotten through two methods.

First is using your bounty parcels to help others raise bounties they've started. These parcels are free and you get them when you do red guard rallies and also when you do alliance events such as the Underground Gates or Red Guard Raids. Use these freely to help your allies and get Hero Coins in return.

The second way to get Hero Coins is to sell unneeded items. In the Hall of Heroes, go to the Hero Store. You can see many items being sold for Hero Coins. You can click on the plus sign next to your hero coin count in the upper left corner to see the items you are allowed to sell to get coins. Guard fragments for guards you do not plan to use are a great way to get extra coins. Also, unneeded materials work too.

Once you have enough hero coins, you can raise your own bounty. Choose whatever works best for your own upgrading needs. Ship experience, Lord experience, guard experience, steel, etc are all favorites.

Sorry for the long answer but there's a lot to bounties and the hall of heroes. Have a look around.
