Superior Rune of the Vampirism
As i know this bug was reported 5! months ago:
https://forum-en.gw2archive.eu/forum/support/bugs/Superior-Rune-of-Vampirism-Bugged
Anet dev say: Thanks for the reports! We’ve documented and are investigating this issue.
And its..
STILL BUGGED..
so they need more time
I’ve been using these runes for months and they work perfectly fine…the 2 and 4 bonuses will heal for an extra 1k, not sure if that is affected by healing power or not. But the runes are great and work great.
I’ve only noticed the 6th bonus triggering in DS when my actual health is below 10%.
