I would like to edit some weapon damages of installed mods, because some of them are way too high.

How can I open the .esp′s and edit the damage? In the creation kit no weapon is shown under "weapons", and I can′t open existing esp′s.

Are there any alternative modding tools for that?

Thanks in advance!

EDIT: I suppose the damage is shown wrong, don′t know why... And it seems only bows and arrows are affected.

For example: The damage of iron arrows is displayed 1 (normally it′s 7, as far as I know), and the bows do very high damage (about 50% more than normal). Don′t know the reason, Is there a mod that set the damage values for bows and arrows to a "normal" level?
