RPG Glossary?

[Lysander]

Has anyone here ever come across a glossary of RPG terms? This is my first RPG forum, so I'm new to a few of the terms, such as "tanker" and "buff/debuff." I've seen others, but I can't think of them at the moment.

What exactly does "tanker" mean? (From context, seems like a troop with strong defense that keeps the enemy busy, freeing troops to attack. Izzat correct?)

Also, what does "buff/debuff" mean?

Thanks.
