Spear Charge didn't (exactly) need more damage

The spear is pretty useless when running or when in a horse/mount but way too op with elytras. Making it do more damage makes it more viable when running and more useful with horses but just makes the elytra problem worse.

Just make it start with little damage, grow damage pretty fast and then grow slower and slower the faster you go so it's still useful in a horse but not too op with an elytra. If not just add a damage cap to the spear depending on the tier or make you take a little damage the faster you go or make it have a cooldown to use again or make it lose more durability the more damage you deal or something. The spear isn't op, but with an elytra there's just little reason to use any other weapon.
