What would a substitute item for a khopesh be ?

I'm thinking Falcion, unless someone else disagrees.

Falchion* Sorry.

Alright, thanks a lot !
Also, do I need to buy Breath of Ki to have the ability to stay underwater for long, but not infinitely ? (3 hours on a cold day, 2 on a hot one)

Yes. That's well beyond a human's capability, so getting Breath of Ki would be appropriate.

It's about what's expected form a crocodile though, just like the bite and the nictitating membrane.

The logic behind it is that a lot of races are naturally more powerful than humans, so we use spells for abilities beyond the capabilities of humans. However, these are substitutions for natural abilities. In places like deadzones and under silence magic conditions, they would still work. This is similar to the requirement for dragon races to have dragonscale armor in order to say that they have hardened scales. It's a balance feature and nothing more.

I see. What about the jump ? It was originally 17 feet but I changed it. Do I still need Minor Levitation for my current jump height ?

Moliira has spoken in your "Severed Heads" help thread and said strength and agility will be fine without also needing minor levitation. 10 feet isn't that crazy.

Alright, thanks.
I haven't checked Severed Heads yet… Sorry.
