I believe steal/waylay is affected by the unit's stats. Not sure which one exactly but higher stats definitely increase your rate of success.
- It is random whether you're able to steal or not. Waylay is 100% successful when Xon is at level 53 because of Bandit (Ability) which changes a 50% chance to 100% chance to steal. --FencerTJ (talk) 05:46, 16 August 2017 (UTC)
