Find Trap Strangely, I can find a few good uses for this spell. It is still not a great spell, but a party without someone able to spot/investigate traps is not completely in the dark with this one.
Find Traps has a similar problem to True Strike. Every time you think you can do something with this spell, you find out it doesn't exactly work that way or that it's just confusing as hell.
For example, you think there might be a trap nearby but you haven't spotted it with Perception or Investigation. Find Traps only tells you that "Yes, there is a trap" and the general nature of the danger. That's... incredibly vague. Learning the general nature of the danger might give you a clue about where the trap is, but otherwise you are still in the same boat. You don't know where the trap is, and you can't find it.
It's also line of sight, which causes all kinds of problems. Such as not going around corners, not detecting anything on the other side of the door, not detecting something inside of a chest, not detecting things through fog, darkness, deep water, around rock formations, or any number of other things.
The wording of the spell is also vague. We've all got an idea of what a trap constitutes, but the wording here specifies "anything that would inflict a sudden or unexpected effect you consider harmful or undesirable, which was specifically intended as such by its creator." So anything not intended to specifically be a trap, such as a storage room full of undead, a trash room full of monstrous slime, or a cavern that just fills with water when the tide rolls in.
Maybe if it had a duration? Or maybe if it was a ritual? Or maybe if it didn't use line of sight? Or maybe if it told you where the trap was? Or maybe if it was on the spell list of classes who didn't already tend to have good Perception?
That's a lot of maybes. And right now it competes with a lot of great Level 2 alternative spells.
