Achievements Worth Fighting For

The Captive: Capture 100 heroes. This will give you a 25% reduction in resource cost of queuing infantry. This is worth doing. The easiest way is to colonize some inactives and Sow Discord their (usually crappy) heroes. If they are no good, release them and do it more the next day. This is a fast and easy achievement to get.

Booty: Acquire 100 items from war. This will give you a 25% reduction in resource cost of queuing cavalry. This should just come naturally through time. Gems and Medals are items acquired.

Medal Acquisition: Complete all 45 medal achievements. This is a very hard one to do, especially on new servers, but the further along you get on it, the better off you will be. This lowers the siege weapon queue cost.

Colonize: Colonize 400 cities. Sounds harder than it really is. Find <1k prestige towns near you, declare on them, colonize them, recall before suppression, and colonize again after suppression battle is lost by you. Keep doing this until you hit 400. This will increase treasure drop by 10% (huge boost)

Enemy Killing: This will come over time too, but this will increase your wounded percentage after battle. I haven?t noticed it working, but haven?t seen anyone comment on it yet either.
