Special rules

• Suwak is a special rule of this game system. It says that when a character has at least four 4 levels in a skill, each time that skill is tested, the difficulty level is automatically lowered by one; if their skill level is 8 or 12, then difficulty is lowered by two or three levels respectively. It's supposed to depict the fact that the more trained a character becomes, the easier those things they trained seem to them.
• Lucky 1 - each time when making a test roll a player rolls "1" on any dice, he is lucky and manages to perform easily; in the terms of mechanics, the test is treated as if the difficulty level was lower by one. Notice: if the player rolls two "1's", the test is automatically successful.
