Larian Studios Forums Divinity - Original Sin Divinity - Original Sin - Enhanced Edition How does the turn order work?

In the original game, the turn order was determined at start of combat and processed in a linear fashion. In the Enhanced Edition, this does not alway seem to be the case. Some characters seem to have more turns than others without disabling effects beeing involved. I noticed this especially if the nasty "Initiative Improvement Aura" is involved so I suspect a high initiative leads to more turns.
Is my perception correct? If yes, can anybody please tell me how turn order is determined?

(The game overall is great, by the way)

To me it seems to be a combination of your initiative, the enemy's initiative, status effects and defense skills, e.g. willpower, bodybuilding, etc.. Once a character is taken out it frequently ends up at the end of the queue and then gets worked back into the rotation based on its numbers. I know they use an algorithm to determine the order but I don't know what it is exactly.

Disabling status effects (effectiveness is influenced by willpower or bodybuilding) obviously prevent a charcters turn, they simply skip and get another chance on their next regular turn (due to my observations). But even without those the turn order sometimes does behave strangely. I can hardly imagine willpower and bodybuilding to have a direct impact, it does not make sense to me.
It may be solely determined by initiative, but I am unsure and it is difficult to plan in advance if I do not know the mechanics (and the bar at the top regularly ceases to function properly).
