Occurrence Rate: Once
The Bloodthirster tooltip showed a very odd amount of added lifesteal that persisted while adding more lifesteal with kills. The actual lifesteal gained was not affected. Dying reset it to normal.
Unfortunately, I have been unable to reproduce this.
EDIT: I have no idea why all the screenshots I upload are so small. The value for the lifesteal in the screenshot is 24.26%.
As per Sulale's suggestion, I've added a link to a larger image. http://i.imgur.com/EMLWoEG.jpg
