> enemy roster
Mechanics-wise it goes pretty far, there are around 50+ enemies each with a lot of different moves and setups available. Some enemies even use stances like you and or have superforms/states. Others have special abilities like summoning other foes or alerting them. There's a bit of everything in here. That said, visually, it's all a bit samey. The game has a TON of bosses though. Nearly 110.
> general tips
* don't worry about stats too much
* just grab the weapon with the highest stats, don't bother sticking to one weapon until you reach Way of the Nioh
* with armor, mostly pay attention to how heavy it is (try to stay in A in agility) and if it has a set bonus. Set bonusses are really good
* Chosing Dual Swords and Kato as your starting class is generally considered to be the go-to way, because of the stat bonuses they give. You can easily get another weapon fast.
* if you want, you can buy the DLC's early. This will give you access to the new weapons (tonfa and odachi) early on, that said they are more built around a fully fleshed out character who has enough points to buy every skill from the get go.
* the game has a TON of different items, most are useless haha.
* talk to Tome. Just seriously, talk to her. Mash that button for a good 5 minutes while drinking coffee or w/e. Gives you a lot of shop-points.
* don't upgrade, soul match, or spend any type of money until the end game (you can spend some, just don't go all out). You'll need all the money you can get by then.
* with items you don't need, make an order. You can generally do three things with them. Offer, sell or dismantel. I generally dismantel weapons and headpieces, dismantel arms and chest pieces and offer legs and boots. This way you'll always get a bit of everything.
* nothing is permanent in this game, you can always respec everything and all. So no worries about that
* side missions are generally really hard challenge maps, don't be afraid to skip them for a while until you have better gear.
* mission levels mean nothing. The higher they are though, the better gear you'll find there.
* beating a boss for the first time unlocks his drop-pool, meaning regular enemies will drop his loot as well. So no need to farm one specific enemy.
