5 more Kleidos Challenges down in Lords of Shadow 2, with 2 left to go.
These would be so much easier if the game's auto-targeting didn't actively hate you. It always targets every enemy near you except the one you actually want to hit. Was nearly at the point of throwing my controller for the first time in decades when I was just about to clear one of the challenges, only for the main mini-boss you're fighting (and who all the other enemies were clustered around) to explode upon death, delivering the killing blow.
Yeah, didn't make that mistake again, but it took me another hour to get that far in that challenge again, as it's one where you can only do damage to the mini-boss while they're frozen with your ice sword's special attacks. Oh, but don't you dare actually HIT them with the ice sword, because that's dealing damage to the boss when they're not frozen! Oh, and considering your special attacks can only be used when your feet are planted and any enemy interrupt attack automatically triggers a sword swipe, guess what tends to happen a lot in that fight.

Then there was the other challenge from Hell, the one generally considered the hardest in the game: baiting another mini-boss into shattering the armor of his 3 helpers without him killing them, and then killing him. Oh sure, you CAN put each enemy at near-shattering with a *single* hit from your chaos bombs...if the targeting system is feeling like it. And the enemy isn't moving. And nothing gets inbetween your shot, like the mini-boss or another enemy you've already hit with a bomb, causing you to fail the challenge immediately. And that's assuming the boss feels like trying to attack you at that particular moment, which he usually doesn't. Oh, and the boss also can't be in his power stance with his swords linked together for more than 20 consecutive seconds, which you can break him out of if you hit him 3 times in a row with your chaos claws. Assuming he's in the guard stance at the time and not attacking you with any of his many attacks. While a countdown timer is in play. And you're probably low on health and magic. And his helpers are ganging up on you.
That one was SOOOO much fun, especially when he would wipe the floor with me on the rare occasion where all 3 of his pals DID have their armor shattered so I could Talisman of the Dragon them to death and fight him 1 on 1.

The remaining 2 challenges look more annoying than difficult, as one's reliant on destroying components of 2 mini-bosses while they're trying to use them (and from what I've seen, they are very picky about using them) and the other is about racing an NPC to kill more enemies than he can under a time limit.
