Question

How works the new Combat Mode or the elimination of that?
How affect every vocation.

Answer 1

To compensate for the bonuses that were lost with the removal of combat mode:

• The attack value of all characters has been increased by 20%.
• The defense value of all shields has been increased by 30%.
• The defense value of all spellbooks has been increased by 60%.

The mitigation formula also needed to be adjusted:

• The type of weapon you wear now has a much larger impact on your mitigation.
• Dedication perks now grant 0.075% mitigation multiplier per promotion point instead of 0.03%.
• Gems now provide 20/22/24/30% mitigation multiplier instead of 5/5.5/6/7.5%.

Furthermore, monster mitigation has been increased.
