If you're choosing the Left path (assuming you chose Eye), and then choosing Aglaecwif lore over Strength & Skill buff. You'll definitely be short on stats to save Laurie. Even on corruption path, if you chose Horn, you'd have 105 power and 26 skill, you need +3 skill to reach the 28 Skill threshold. So if you went with Aglaecwif lore, you won't be able to get +3 Skill.
Assuming you're taking the corruption path, if you picked Eye, AND you fought Michael w/ skill early on to hopefully reach 19 Skill to beat Valravn. Choosing Eye, would put you at a deficit of 10 power. By the time you reach Aglaecwif you'd have 95 power & 27 Skill. You'd be short on both Power and Skill. If you picked either Strength buff or Skill buff, you'd be lacking the stats to save Laurie. You'd need exactly both buffs, but then you're still overall 5 power less than just picking Horn and going Right to fight Red light monster
That said I didn't know you could ask Valravn more questions after getting lore from Aglaecwif
Yeah I'm only talking about the Valravn's follow up. A lot of players don't really care about Laurie and that's to be expected, because characters who can die get very little content.
If you have Valravn's respect, anything you ask Aglaecwif, you can also ask Valravn about it and get his opinion. This is pretty much the only reason to go for the eye as of now, because otherwise you need to either read the raw script or hack the game to get this information. And since generally MC does not use various knowledge he gains in any significant capacity, it's obviously the lesser choice.
An interesting question is if the eye will become better down the line.
WW tends to be explicit with his variables. Technically, the same variables used to close menu items, can be used to determine if the player has used the eye, but as of now, he has never done such a thing. This makes me think that he isn't interested in tracking it. So these are the possible scenarios IMO:
1) If the player has met Aglaecwif while in possession of the eye, that's all there is to it.
2) If the player has not met Aglaecwif while in possession of the eye, it may become relevant the next time he meets her. Since this meeting will take place at a later time, and MC will be more powerful, I think that a +10 power / +3 skill will not cut it. So I expect that if this scenario happens, the rewards will end up being more significant, which may change the optimal path for max stats.
After all, the game isn't yet half done, so I expect many things to change down the line. Like how asking Tiffany for power became the better choice in this update. Money may end up becoming better if there's an important item that the MC can't possibly gain enough money to buy.
