'To Hit' Tables

Well, I believe the tables need some explaining. First of all find your class (mage, cleric, fighter, etc.). Then look at the top row to find your level. Now find the Armor Class of your opponent at the left column. The number you get is the base 'To Hit' number. Apply the bonuses (eg. bonus for Proficiencies, magically enchanted +X weapons and so on..) and the new number is the final 'To Hit' number.

Then a 20d (20-sided dice) is rolled, resulting on a number from 1 to 20. You make a successful hit (one that deals damage) if the number rolled is equal to or higher than the final 'To Hit' number.

This may result in a situation where a very weak character can never hit a very tough monster or where a very strong character will always hit, something not realistic at all. So, a roll of '1' is always a 'Critical Miss', a '20' is always a 'Critical Hit' which doubles the damage done, unless wearing something that negates this effect such as a helmet.
