Superior rune of the Firebrand

[Vajra.3914]

I just noticed not, but the Superior rune of the Firebrand has those bonus:

1. +25 condition damage
2. +5% boon duration
3. +50 Condition Duration
4. +10% boon duration
5. +100 Condition Duration
6. +20% quickness duration; when you use an elite skill, inflict burning on nearby enemy (45s cd)

Now, I know that it can't be +150% condition duration, so is it conditin damage, or actualy expertise? (can be bothered to spend +15g to test myself)

Edit: Just now I read in the wiki that is condition damage, so it's just a typo?
