Encounter with the Sword Spirit | Upgrading your character classes Angry Birds Epic Guide

That's how the building you must travel to look like.

Upgrading your character classes in Angry Birds Epic is fairly simple - all you have to do is to find the right place to do so, have the required amount of given currency, and you should be able to upgrade your desired class. Before you can do that, however, you will have to defeat a single enemy - Sword Spirit. He is located in a place called Mighty Eagle's Dojo, which can be accessed after you've finished Old Nesting Barrows 4.

Sword Spirit

Sword Spirit	Abilities
	Angry Bird - the enemy prepares for 3 turns, and then unleashes a powerful attack against one of your birds. Fortify - decreases damage taken by 55%. Effect lasts for 3 turns. Duel of Honor - prevents you from using potions.

Explanation

Sword Spirit is no one else then Red, wearing some stylish clothing. The whole encounter would be a piece of cake, but there's one irritating thing about it - you can fight him with a single bird only (at least you can pick the bird you want). There's really no point to list the birds which are effective against him, because the fight itself isn't really all that hard, and every player has probably developed a liking to specific birds / classes during his / her playthrough.

The enemy starts the encounter by casting Fortify on himself - it severely decreases the damage you can deal to him. Afterwards, he will start preparing his signature attack - Angry Bird. Basically it means, that you will receive first dose of damage at 4th turn. If you managed to survive it, the next attack will come at you in 7th turn and so on. To increase the probability of success, you should choose one of the following birds :

• Red - because his classes allow you to decrease damage taken, while still having at least decent offensive capabilities. The best choice for class is a Knight or a Samurai.
• Matilda - because she can heal herself (provided that you survive enemy's attack).
• Blues - they can deal one of the highest damages in the game. Use the Rogues class - Damage over Time will increase the damage received by the enemy.

The rest of the birds aren't really suited for this fight - Bomb does not deal enough damage, while Chuck is strong versus swarms of enemies, not a single foe. After the fight you will be shown a short cut-scene, and you will gain access to the secret Mighty Eagle's Dojo.
