When you are RPing are you guess wtriting it out, not using anything these like dice to think out if you hit the urgal. I'm use too D&D so whatever help I can get thanks.

You use what you think your character would be able to accomplish, based on how skilled they are, what sort of limitations they have, if they have weapons or are abe to use magic at the time, ect.

You can kill hundreds of Urgals in seconds if you wanted to that much...but heh, that may get you blocked from RPing and others may ignore your posts.

yea it is not good if ur charater is too powerful

So there's no real fix rules then.
For example on the froums its: I kill an urgal
With rules its: I roll a 15, passing the armor class of the urgal and roll a 8 meaning I deal 8 damage.

Honestly, it's not fun to RP with a godmoding person. It is rather annoying, I do admit I have done that a few times. I have fixed that problem though.

Ya, I agree with Erias. I always used to do that. If I still do a little (which I hope I'm not) please tell me.

As has been said, you just think what your character might be able to achieve at that moment. For example, if they had just been injured they might not be able to kill the urgal- if they are strong they probably would. There are no fixed rules really, just don't make your character too strong or always powerful because that's just annoying and makes the RP boring for everyone else.
