elven long sword question (in General)

is it better or worse than an exec and about how much more is it valued than an exec

Better according to most people and at least 3-4 mil more worth?

i have An Executioner's Sword [82x57] (+35) 3,483,134
at what point would my sword no long be a good trade for an els with no money added

ELS are better for 2 reasons
1) One handed, so if you have a BoM, ELS will be a better choice
2) easy to upgrade, when you try going for X100 +100, you'll need an ELS

Though I'd advise against ever doing this you'd probably have to upgrade you exec to the range of 8 mil net worth to have market value as a base ELS. O_o

If you've got your eye on one I'd advise getting ready for a long haul of saving and or forging, or kick in some USD.

thank you
