How to suck during combat/ sneak attack?

[m00n]

Can't figure out how to shadowwalk / teleport to an enemy before combat.
Can't figure out how to bite/suck blood during combat.
No sneaking.

Game tells me that I can do it, but not how?!
No hint in controls, even after unlocking skills.

the yellow bar is the stamina bar, use guns or stakes or other stamina draining abillities to drain it and once its drained press f to bite them. Also, the teleport to an enemy is a skill you unlock. hold q to walk is how you sneak.

Walk don't run to your target. As long as they are not aware of you, when you get close, press F to knock them down and then F again to bite feed on them. Also you can use the offhand weapon to knock your opponent down and then feed on them too.
