First, with all the modifiers there are several options for roll results. They are:
1 -
Epic Fail You have failed. Terribly. You not only managed to fail, but also managed to hurt yourself in the process.
2 -
Failure You have completely failed to accomplish what you have set out to do.
3 -
Minor Success You either accomplished part of your goal, or accomplished it with some minor detriment to yourself.
4 -
Success You did what you wanted to do. Nothing more, nothing less.
5 -
Epic Success You not only did what you wanted to do, you got some nice bonuses as well.
6 -
Mild Overshot You did what you wanted, but maybe a little too well.
7 -
Overshot Well, you've done what you wanted, but there are negative side effects to it.
8 -
Big Overshot You put too much power into something, or otherwise gone about your goal in a destructive manner; your objective is completed, but you've probably killed something in the process.
9 -
Massive Overshot You've done it now. Things will go up in flames, most likely including yourself or whatever you're trying to obtain.
10 -
Godly Overshot Shit has hit the fan. HARD.
11 -
Well, this can't be good...Next, up Skills
There are different types of skills in this game, all explained here. But first, leveling. Skills are leveled up through use; so if you want to get better at using your blaster, you'll need to use your blaster. Getting a 5 or 6 gives you experience in a particular skill. So, if I use a blaster for the first time and roll a 5, I gain level 0 in blaster use. Each consecutive level requires your level+1 more rolls of a 4 5 or a 6 to gain the level, but once you gain the level you gain a permanent +1 bonus to that skill (those bonuses stack with each new level). Levels go up to 5.
The list of skills are as follows:
Melee Weapons (sword, hooks, flail, etc.)
Blaster Use
Unarmed Combat
Vehicle Use (allows bonuses to movement and ranged combat within vehicle mode)
Repair
Speech (you'll need to be convincing to become influential within your faction)
Hacking
Combat Agility
