I am quite new to this game and yet to fully understand the usage of different runes but this is my take if you think I am wrong please comment and feedback thanks. Basically the heros are divided into 2 groups tanks and casters. And the tanks are sub-divided into cavalry, archer,infantry right? I am still not familiar on the different gold and purple troops so maybe there if some of you seniors would be kind enough to share with me? So... lets get started will name the rune then the class its best suited followed by its function.

1. Guildmaster-Adept : Infantry
Increase skill damage

2. Retaliation-Bane : Cavalry, infantry and archers
Increase physical damage

3. Trance-Focused-Intenseness : Mages
Increase magical damage

4. Eagle-Hawkishness-Preciseness : Mages
Increase hit rating

5. Superiority-Advantage : Cavalry, Archer and Infantry
Increase critical hitting rate

6. Destruction-Eradicator-Infalability : Cavalry, Archer and Infantry
Increase break rating

7. Wall-Resistance : Cavalry, Infantry
Increase block rating

8. Agility-Nimbleness : Cavalry, Infantry
Increase dorge rating

9. Cunning-Phantom-Dexteriousness : Infantry, Archer
Increase resillience rating

10. Crusade-Partisan-Righteousness : Cavalry Infantry
Increase morale

11. Vigor-Vitality : All classes
Increase Max HP

12. Tactics-Flintness : Cavalry, Infantry
Reduces skill damage taken

13. Mountain-Mesa-Burliness : Cavalry, Infantry
Reduces physical damage taken

14. Tranquility-Messiness : All classes
Reduces magic damage taken

PS if unsure put the rune in the hero circle if your power does not increase chances its not ment for your class unless its moral somehow power don't increase but it hits faster.
