Lu Bu can not only be recruited as a companion in Dynasty Warriors Origins, but you can actually use his Peerless Halberd. But to get Lu Bu’s Peerless Halberd (Rampaging Luan) in Dynasty Warriors: Origins, you must complete specific post-game challenges.
So, it goes without saying that you first need to complete the game’s story mode on any of the available difficulties.
How to Get Lu Bu’s Peerless Halberd
As I said earlier, complete the story mode as any faction (Shu, Wei, or Wu) on any difficulty. Doing so unlocks Halberds as purchasable weapon type on New Game+.
Next step is to go to any weapons shop in new game+ to purchase a halberd (for example, sky piercer for 400k gold). This means Halberds will now be available for new drops in the loot pool.
With the weapon added to your loot pools, defeat Lu Bu at the Battle of Hulao Gate on Ultimate Warrior difficulty for a 100% drop chance.
Successfully defeating Lu Bu also grants the Rampaging Luan, which boosts Musou Attack strength by 20%, Battle Art strength by 10%, and Bravery gains.
Peerless Halberd comes with an ability called War God Rage. When triggered it increases range, attack, and damage.
