Does Wyroot do ANY damage on a critical?

[AzureKnight]

Here is the text from the material:

"When a weapon constructed of wyroot confirms a critical hit, it absorbs some of the life force of the creature hit. The creature hit is unharmed and the wyroot weapon gains 1 life point."

When it states that the creature hit is unharmed does that mean unharmed by the life force absorption or unharmed by the critical hit?

I can see it reading two ways:

1) The target is critically hit (takes critical hit point damage) and has its lifeforce drained (which doesn't harm it in any way-no negative levels, loss of con, other things associated with that concept, etc).

2) The target is critically hit (takes no hit point damage because it is unharmed) and has its lifeforce drained (which also doesn't harm it in any way).

Am I the only one confused by this?

Pretty sure #1 is correct. The wording is confusing, but it makes no sense that a critical hit would not only not do extra damage but would do no damage at all.

The wording is pretty weird, I guess they just wanted to point out the the damaged target doesn't get a negative level of something like that.
