How Status Effects Cause | Divinity Original Sin Wiki

Status effects are caused by spells cast on characters or on the surfaces on which characters walk. Characters get a saving throw against these statuses. For example:

• The skill Freezing Touch has 100% Chance to cause Frozen status for 2 turns.
• But if you have the Ability Willpower -- the chance of you being Frozen is reduced by 15% for each point of Willpower.
