Revenant vertebrae could use a buff

The psycast Invisibility can be cast multiple times if you have enough focus. Good one to get out of dodge and around a corner

But the Revenant spine has a 1d cooldown, which I think is way too much.

It would be great if it either lasted much longer (1min or maybe last forever until you turn it of or do an action) or had the cooldown reduced, because as it is, you can't get very far with 15s
