First of all, welcome to FiestaFan and enjoy your stay here.

Now, for the questions;
What is DPS?
DPS is Damage Per Second, the rate of how much damage you inflict to a certain monster over a period of time, which is seconds. Mages and Archers have the highest DPS in FiestaOnline.

What is grinding?
Grinding is when you train/level hardcore. When you grind, hunger and thirst is disregarded over long periods of time, though I may be exaggerating quite a bit.

What is AoE and what is the purpose of it?
AoE means Area of Effect. AoE skills focus on more than one object/monster, they have an area range where their effect takes place, whether it be damage or a de-buff.
