I need attack rolls from everyone. You have a spear, you are +15 to your effective skill rolls (+5 for Cedwyn's battle roll, +5 for being mounted against someone on foot, and +5 for a charge). If you are fighting with a sword, you are at +10 effective skill.
Any numbers above twenty get added to the actual roll, and any result 20+ is a critical.
Those of you with spears use your horse's damage stat. Anyone else uses their own damage stat.
If you have a sword instead of a spear, you can attack two opponents. Allocate your modified skill roll against each opponent, and make separate rolls. For example, if you have an effective 25, you can split it so you use 13 against one opponent, and 12 against the other, and determine success or fail separately, and use your personal damage stat.
Any questions, let me know.
