Get Red Hare asap - You unlock Red Hare for purchase by completing Guan Yu, Dong Zhuo and Lu Bu's storyline. Once unlocked purchase for $100,000. Best horse in the game. At level 1, it has higher stats than a lvl 100 birch.

Gold Crown: Get yourself a gold crown asap, it sucks all nearby items to you and it has a crazy range. very much worth the item slot.

Beast Mirror: Beast Mirrors increase the area of the map you unlock as you travel through it, the beautiful thing is these stack, so when exploring is your goal, stack 4 of them.

Fire Gems: Fire Gems are (IMO) the best for your weapons, they add insane damage to your attacks and with the new combat system, its seriously easy to keep the elements up.

Headshot: You can headshot most human enemies with a bow for them to die in one hit. Even on Choas mode. Head toward the great wall (Far north west) and head shot bandits on choas. Great source of gold, coins and exp.

Chen Pu: I found this new comer to the series to be one of the best characters to grind the 100,000 KO's on. Dude is smooth.
