Basic Game-Play Knowledge For Advanced Dungeons & Dragons 2nd Edition -

Thaco:
Thaco Vs. Armor Class--
Fighter Thaco 19 - The Goblins 7 Armor Class = 12
This means the player playing the fighter character needs to roll a 12 or higher on a d20 to hit the goblin.

Thaco Vs. Exceptional Armor Class--
If the armor class number looks like this "-2", you do this math.
Fighter Thaco 12 + Dragons -2 Armor Class = 14
This means the player playing the fighter character needs to roll a 14 or higher on a d20 to hit the dragon.

Plus one to attack would simply lower the thaco by one,
and a plus one to armor class would lower the armor class by one.
Ignore the word plus, and considered it an "improvement" by one.
-----------------
Skill & Ability Score Check Rolls -
Roll below the number listed.

Any plus to these dice rolls raises the target number you must roll(or below) to succeed.
-----------------
Saving Throws -
Roll above the number listed.

Plus one to a saving throw would lower the saving throw target number by one.
Ignore the word plus, and considered it an "improvement" by one.
-----------------
Beyond this there are dice rolls for duration and healing, but that is not knowledge all players will need to know.·····HHfVLZJy
