Question on a particular phrase in the Dhampir "Blood Feaster" feat.

[Andru Watkins]

Here is a snippit of the feat:

Consuming blood gives you superhuman strength.
Prerequisites: Blood Drinker, base attack bonus +6, dhampir.

Benefit: If you use your Blood Drinker feat to drain 4 or more points of Constitution from a living creature, you gain a +2 bonus on damage rolls and a +1 bonus on Strength-based skill checks. This bonus lasts for a number of rounds equal to 1/2 your Hit Dice.

The very last sentence regarding Hit Dice, does it mean the type of hit dice I roll or the number of hit dice I have in total?

For example rogue has d8. Bonus lasts for 4 rounds

Or

Rogue is level six therefore has 6 Hit Dice. Bonus lasts for 3 rounds

[tifton]

The second one 3 rounds. The d8 is the amount of hit points in 1 hit dice.

Alright, that clears it up. Thank you!
