GMST Class Testing

They stack, answered earlier.

One last question about DoT, does DoT from the same skill but different players stack?

I don't think the same DOT skill from others players stacks. Maple just can't handle that.

A monster can only be put into 1 state per DOT. It's the same like trying to freeze a monster with 2 people, the new freeze will freeze the monster again, not twice. You can freeze + poison it though, that's why you can put multiple DOT's on a monster -if- the DOT's are from different skills.

But I haven't tested it post-BB though, it's just how maple always worked... But maybe it got changed with BB...
