The terminology used here exists in countless games, roleplaying, video, or otherwise, and enough weird words and names have been brought into the mix for Alatha so far, so there is no need to re-invent the wheel on this one. (Dang that was a long sentence.) For those of you unfamiliar with terms, the following should help explain some of the jargon.
Spell and Feat Terms
AOE – stands for Area of Effect. A spell which targets an area rather than an individual, those in the target area have their dodge reduced by half since the entire space will be covered by the effect. An aoe takes up nine spaces with the center space as the target.
Centered AOE – An aoe centered on the caster, rather than a selected target.
Buff – something that positively affects a friendly target, self or other, lasts 1D+2 rounds
Debuff – something that negatively affects a hostile target, lasts 1D+2 rounds
Aura – a combination aoe / buff or debuff. An aura is centered on a character and affects all in its area. An aura may be passive
Passive – a buff of sorts that constantly affects a character once it is learned
Stance – the manner in which a melee character stands gives some benefits but also sometimes a weakness. A character may only be in one stance at a time, but that stance stays in effect until a character chooses to not be in that stance or switches to another. Ceasing to be in a stance is a free action.
