SAMURAI WARRIORS 5 (EP)

There are 70 levels across all of Nobunaga and Mitsuhide's stories, as well as the Reverie Chapter.

You must successfully complete all 70 in order to claim this.

While there isn't a ton you can do to speed up these levels, there is a way to make completing them trivial.
I've located this guide:


Which details a way to make a rather OP weapon, which allows you to move extremely quickly, even at low levels, and essentially lets you melt enemy officers. This weapon even works on Nightmare difficulty.

To re-iterate the video, you will need to find an 8-slot silver tier weapon of any kind, and use the blacksmith to forge it into a Ninja Blade weapon.

Once you've done that, add skill gems to the weapon. The following skill gems are recommended by the video.

Attack (Mandatory)
Attack Speed (Mandatory)
Projectile Attack
Dominance
Courage
Momentum

I've attached Range and Underdog to my copy for the final two slots, as increased attack range helps greatly, and you end up knocking enemies airborne quite a lot, so Underdog allows you to do bonus damage while they're in the air.

Keep in mind you may need to use weapon XP to bring new officers up to speed to be able to use the ninja blade. I made two at differing weapon tiers to allow them to use a less-OP version of the sword and work their way up to the S-rank version.
