Lunge is a brilliant enchant right up until someone realises nothing stops them doing it over and over. Swing, fly forward, swing again. You can chase someone the length of the map and never run out.

So now you get three. Spend them all and the spear dpesn't for 30 seconds. Same little cooldown ender pearls give you, sat right on the item, so you can see when it's coming back.

While it's on cooldown the spear does nothing at all. No lunge, no damage. After the 30 seconds you can lunge again.

Want four instead of three, or a shorter wait, or just the bar without the lockout? All in the config.
