Basics
Check
Roll d10 + STAT + Skill + bonuses. Roll a 10 — roll another d10 and add it; roll a 1 — roll another and subtract it.
The GM calls for a check and names the Difficulty Value (DV). Beat the DV — you succeed.
The sheet adds up everything except the die for you: tap a skill, enter what you rolled and see the total. The wound penalty is already included.
