Aiv can, definitely, but just don't expect the same result like how it happened earlier. 

I will never say you [b]can't[/b] do something, unless it is literally impossible. What is possible is for players to judge themselves, based on their status and stats, though I will always provide some input to help guide them. The way I usually do consequences too, is put characters in tough situations, leave them vulnerable if they do things outside their current ability, or have the action happen as intended, but with a weaker effect. Sometimes, they just straight up take damage. If you have a certain idea of what you specifically want to happen, we can always discuss that sort of thing here... or in PMs, or whatever. 

If things get too complicated, I might just open up that chat service... i dunno yet.
