Psh, I think there are plenty of feats you can do in this game. ;P A lot of people simply don't consider feats that are too hard for them feats.
Even regular trophies can be a feat on their own, depending on their difficulty. Well, guess that's why they are trophies?
One Moment in Time: Save Alexandra from Sakkara, meaning you have 30 minutes to get there. Pretty much means your run has to be flawless, from start to end.
Friendly Fire: Don't kill any of the possessed bats. Starts out with literally no damage, but as Claw is stacked higher and higher, you end up with hundreds of damage every other second - on your entire group. Once Sakkara starts possessing, it's a mad dash to get the boss down before the damage becomes too much for your healer to handle. Look at Cay's health bar - how much is left, 5%? Oh yes, and that's on top of Sakkara's regular abilities, which many can't get past already. No doubt these will become easier with the release of higher levels - but having completed them at the appropriate level (with the appropriate difficulty) remains a feat, and as such will actually go in the "Feats" section of your trophy list. :3
That said, killing the Deep Cave Lurker alone is pretty neat. ^-^
