I accidentally gave a Steel Longsword the following enchantment:
Absorb Health 15 points
Cast when *used*

Oops!

I found out the mistake when fighting a Cliff Racer and was wondering why the effect wasn't triggering. A few uses of it as an item, however, and it fell and I was healed.

By the way, what is the best restocking item for cast when used effects I could buy? My requirements are as follows:
1. Light (weight 1 or less)
2. Decent number of enchant points (at least 6)
3. Some merchant restocks them

Fortunately, I was able to buy another Steel Longsword and gave it the same enchantment, but cast on *strike*.

As I understand it no one restocks anything with a particularly high enchant value... However, there's a nice fetch list on UESP wiki telling locations of exquisite clothing.
