 Guild Battles
For more information on these changes, please see the Developer Updates page.
- Removed the reduced durations of hexes and conditions on the Guild Lord so that they last the normal amount of time.
- Refined how aggressiveness is measured for teams in Guild Battles. Dealing damage to the enemy Guild Lord still increases your team's aggressiveness. Casting enchantments and weapon spells on your Guild Lord now decreases your aggressiveness. If neither Guild Lord is killed before 28 minutes have passed, the more aggressive team is awarded the victory.
