Alliance Bosses

Alliance Bosses
The Alliance Bosses are summoned randomly by hits on the High Pass, Mirkwood and Moria campaing maps. When they appear, they also show up in the "Alliance" > "Boss List" page. The lower level bosses are easy to kill and as they go up 20, 30, 40,etc. the number of troops and the level of the boss increase, making it harder to kill with one attack.

Attack
As long as members are attacking the campaign maps to summon plenty of bosses, attack with the most force available. Since the battles here are different than other attacks, you can send a large number of troops and only lose a fraction of them, even when you don't kill all the goblins.

Send as many T1 foot troops as you think will be killed...start with 15,000. In addition to those, add as many of your highest tier troops as possible to maximize damage to the boss. If your maximum attack limit is 100,000, send 15,000 T1 plus 85,000 of your highest troops.

Use your highest hero with the best gear you have. Pifered, Ent, Havoc and Dirty are good for this task. Using a rune of Fury or Invulnerability aren't a good idea since they will run out before you can make a second hit.

Prizes
The Goblin Raid chests contain Gatherers Stones from level I (boss 20,30) through level X (boss 200). The stones inside can be used to increase Resource Collection in your city guardians. This increases yield of resources produced in your fields for city with the upgrades.
