Weapon advice please...

Ok so i found an interesting weapon just now:

Shocking Longsword of Enchanting
15-22, 18% <50%, Enchants last 20% longer.

Now, i run a very heavy enchantment dependent Air Ele build and saw that perfect enchant hilt and started wondering. What i use right now is:

Hale Air Staff of Enchanting
11-22, 20/20 air skills, +27 health, +16% enchant duration.

So heres my question. Would it be more beneficial to use this new perfect longsword and a collector storm artifact, then my current staff? It does give me the 20% enchant duration despite having no skill in swords, but i would be losing 27-30 health potentially from the staff. I can't decide, help me! =)

The question is..is how much time will the sword add on?

for 30 seconds it will add on 6 seconds.

For the Staff

for 30 seconds it will add on 4 or 5 seconds (if its round up or down I do not know)

Unless my math is wrong..But anyway I'd stick with the Staff..The sword will cause you to go melee..and Elementalists don't really have a high amount of Armor level.

Wish i knew if i rounded up or down, does anyone know? And the melee thing is a bit annoying im finding, but it's not like i ever did dmg with a staff either and i can just back up to cancel meleeing if i do it by accident in an area where me running up to a mob would be bad . But anyway, those are good points.

Heres another quick question, whichever i end up using, i will probably sell the other. Anyone know what either item would be worth approx.?

ask yourself, is the +1 seconds for enchantments worth losing 27 health? stick with the staff.

id stick with the staff and sell sword. i bet if you can get the 20% enchantment hilt you could sell it for a good penny!

I guess i should stick with staff huh . Oh well, i'll miss looking somewhat unique carrying a sword. So anyone wanna buy that sword?
