A unit with this ability may reincarnate upon death. Whether they reincarnate into the same or different form (or at all) depends on a number of factors explored by Loggy, but the main takeaways are:

• Reincarnation can only occur inside the reincarnating unit's god's dominion
• Non-commmander units need to be experienced in order to have a chance at reincarnation
• The number in brackets after this ability's name indicates the maximum chance of a successful reincarnation, provided all prerequisite conditions are met, not a fixed chance (e.g., while a Guru may have a 1 in 2 chance of reincarnating under ideal conditions, in reality that chance may be lower, but never higher)
