Bugfixes
The skill “Lightning” got fixed and adjusted. Before the duration of the rooting effect could be longer then maximum cap allowed. Now the overall duration was reduced but the duration cap was removed at the same time .
Fixed a bug with the skill “Shadowstab Perfection”. Before it got rid of Shadowstabs dexterity-damage bonus, lowered the base damage of its bleed effect to 4 instead of 5 and only added 2 seconds instead of 4. The description of Shadowstab is still missing the dexterity-damage bonus (only if you have the Shadowstab Perfection) but this will be changed later.
Fixed a bug with the skill “Sacrifice” where you could use it without having a pet.
Belathis Fortress: The quest "Joining the Fight" can now be completed without defeating Maderoth.
Goblin Mine: Fixed a bug which increased mob amount according to amount of players.
