I am pretty new to the game and I have some questions about weapon enchantments on staves. My confusion arises from the fact that staves already have an effect, e.g. fire with inferno. When you add a weapon enchantment, does it override the base effect? For example, if I have a lightning staff and add a glyph of flame, does it now cause fire damage or fire and lightning?
What occurs if a duplicate the base staffs effect? If you put a glyph of shock onto a lightning staff does it just not do anything additional?
How does adding oblivion damage affect any of the staves?
Finally, at least for now, when you add the charged effect onto a staff, it increases the chance to apply status effect. What effects exactly are being increased and how do I determine what the base chances were to begin with.
Thanks.
