MOST IMPORTANT THING I WILL SAY ALL DAY : HAPPY BIRTHDAY SCARIFAR!

Less important things: I'm going to agree that Jack's powers need some tempering, and some of the issue is from an OOG perspective. It is cool to have a stubborn character IG, but changes to the CS, backtracking on what has been already written, and other things said in the OOC are rubbing us the wrong way. 

For example. In your CS it stated a weakness to cold environments. When it became applicable IG, or as soon as you realized there was an icy-character, you immediately recanted that weakness. I'm not sure why a cold environment would affect your character MORE than a DIRECT cold blast. And how cold are we talking, fridge? antarctic? so your character has no weakness outside of the arctic circle? I feel like the vagueness in the CS has been used as a sort of OOC dodge. It woudl be one thing if it was a completely IG trait like your character has to feel like his is invincible and will not admit weakness... I think Yog, should consider [i]embracing[/i] weaknesses rather than avoiding them. It makes for a more dynamic well rounded character and game. No one should be able to floor the whole team, everyone should have someone they can beat, and someone they can't beat, it makes for a better group dynamic overall, better writing, a better game. Everyone wins when anyone can loose. If that makes sense.

I think being specific about the temp is important to science. Just so if there is a question we can always look up "X material melts at X temp" or whatever. There are a few things to examine. Why don't his cloths catch on fire? If the oil does not burn then it has to go somewhere, so if he doesn't burn it, like what happened IG, that oil is all over the floor now... because he was secreting... Also, bullets explode at high temperatures because they contain gunpowder. If he covers his whole body in the stuff he needs to think about that if he is carrying a shotgun.

I am adverse to adding a power before we have finished the first mission. As Fam said, we are all training and underdeveloped characters. Linn is not like the character refereed to. We are all supposed to be like level 1. We will get to those other levels but there is no need to add stuff before we have even started. So no need to add powers now, especially when the first power is plenty strong.
