Appropriate level for spell?

[Guy Lombard-O]

2nd, 3rd, or 4th? Or shouldn't exist at all?

Devil’s Sight
3rd Level transmutation
Casting Time: 1 action
Range: Touch
Components: V, S, M (pinch of cremains from a sacrificed cleric or ranger)
Duration: 8 hours

You touch a willing creature which has darkvision, and grant it the ability to see normally in darkness, both magical and non magical, to the same range as its darkvision.

I'd go with 2nd level, and reducing the duration to 1 hour/CL. Since the target has to already have Darkvision, there are already restrictions. Why the stated material component? I'd see that as making the spell "Evil" and rather difficult to obtain.

I would say 3, as darkness and daylight are 3. That might lead to some interesting counterspelling, like 2 spells that counter darkness.
