Dark & Light is in maintenance right now to deploy a patch that is designed to directly impact community and player feedback about a variety of balance issues. Most notably, building strength will be increased as will certain protection spells.
Other major balance reduction and adjustments against structures will be applied to:
- melee weapon damage reduction
- creature damage reduction
- spell damage reduction
- projectile damage reduction
- lightning bold reduction
You can read the more specific details on the Dark & Light Steam page.
