I would like one, if not all, of these upgrades to happen. Granted, I know none of them are going to happen, but a man can dream. I'll number them in order of importance, in my opinion.

1.) Charge Attack Buff

The charge attack sucks. You leave yourself open to do a combos worth of damage, all while standing still allowing monsters to run and for you not to block.
Suggestions on improving:

A.) Increase the speed of the combo. (Double or even Tripling the speed would be recommended.)
- The point of this upgrade is to make the combo attack initiate as fast as possible, making it viable and keeping the player safe.

B.)Slash Wave
Simply by taking the last slash animation of the charge attack, and creating a long ranged attack from it, we can revive this weapons usefulness and in a non-overpowering, factor. Perhaps we should increase the charge time on it, to make it a bit more fair though, but aside from that this seems legit to me.

2.) Wild Hunting Blade Change.
The Wild hunting Blade is an inferior version of the Vile striker. The Vile can poison any enemy, while the Hunting blade can only do more damage to one type of enemy, beasts, which a piercing weapon does the job of much better. I mean, this weapon contains a yellow wolf soul, and it's weapon that has jagged edges and ghost teeth biting at you has no piercing elements to it?

The Wild hunting blade, in my opinion, should either:
A.) Become Full Piercing
B.) Become the first Hybrid of Pierce/Normal.

A wolver damaging weapon doing more damage to wolvers? Seems legit? This wouldn't make this weapon overpowered anyway, it would just make it a piercing weapon that pierces those annoying wolvers with even more pleasure then the average leading brand of pierce.

3.) Ethereal Strike Speed Increase.

The "secondary" slash on the cutter series isn't bad, but it has a chance to miss due to the swords knockback sometimes.
I recommend making the slash come out faster so that this occurrence doesn't happen.

Note: The Ethereal strike only misses about 30-40% of the time as is, which isn't horrible, but it shouldn't miss. Granted the pushing forward allows you to push to a wall easily, it shouldn't happen.
