For the Season 9 PUP, you can get Siege arrows/bolts on your units that does higher damage against buildings (and Siege as well, from another bug) after researching Incendiary Arrows. For any Mounted Archer that gets Siege arrows, they can animation cancel by moving, shooting, moving, shooting, etc. on buildings.
This allows them to ignore the reload time of the Siege arrow and get higher DPS against buildings.
Affected units:
- Horse Archer
- Camel Archer
- Onna-Musha
- Mangudai (maybe?? they shoot fast so it’s hard to tell)
