Problems Understanding Lore Warden's Know Thy Enemy

[Flames of Chaos]

Here goes:

Know Thy Enemy (Ex): When the lore warden succeeds at a Knowledge check to identify a creature’s abilities and weaknesses, she can also use a standard action to grant herself a +2 insight bonus on all attack and weapon damage rolls made against that enemy. This bonus lasts for a number of rounds equal to half her class level (minimum 2 rounds), or until the lore warden uses this ability against a different creature. At 11th level, she also gains a +2 bonus to her AC against the creature when using this ability. At 19th level, the insight bonus increases to +3.

So my question is, do you have to do a new Knowledge (whatever) check each time you fight a new monster in combat? Especially if they're multiples of the same monster? If not, how does that work?

Example: Ionius, lv 11 Lore Warden is fighting against 5 zombies. He uses Knowledge (Religion) to identify one of the zombies, and gets a total of 25. (10 ranks in Know Religion, 3 from class skill, 2 from INT). He uses a move action to base the first zombie, and converts the standard to a second move and activates KTE. Does that mean he has to make a new KR check for the other 4 zombies? Does this also mean he has to split his 5 rounds of KTE (11/2 = 5.5, rounds down to 5) among all 5 zombies?

Thanks!

new check every time. it looks to be worded per enemy.

i have no idea what you mean by "base" the first zombie
you can't convert the standard to a move AND activate KTE. KTE is its own standard action. Identifying a creature is a non-action.

"Action: Usually none. In most cases, a Knowledge check doesn’t take an action"

“Base” means moving next to the enemy (it’s from miniature games where certain types of attacks can only be done when the minis are in base-to-base contact).

Ionius identifies a creature (hey, it’s a zombie!) as a free action. If it’s a group of five zombies, then one check is probably sufficient for all of them unless they have different templates or class levels. You pick one of them and use a standard action to use Know Thy Enemy against that one particular zombie. He has 5 rounds of bonus against that one particular zombie. He can use another standard action (on another turn) to use Know Thy Enemy against a different zombie, and that also lasts for 5 rounds. However, as soon as he does so he loses the bonuses against the first zombie.

The narration of Know Thy Enemy according to the rules does indeed get strange when all the enemies the Warden is facing in a given fight are identical.
The ability speaks of abilities and weaknesses, those would apply to each enemy. How come the Insight bonus doesn't?
Furthermore, what if the enemies are indistinguishable from one another, even after having sustained a few blows?
What if it is an ooze that splits?

Keep in mind that not every outsider/undead/monster/etc. looks exactly the same, even if your gm uses the same token for them, just as not every person looks the same. It makes perfect sense to have to reidentify that a monster is the same upon seeing a second one.
