Item Stacking Rules
Item stacking determines whether multiple copies of the same item effect can affect a unit.
General rules
- Some item effects have a max stack limit.
- If an item effect has a max stack limit, Banner-shared copies still respect that cap.
- Some effects can stack indefinitely, such as attack-speed effects from Light Speed Feather.
- Some items do not transfer through Banner even if equipped on Banner.
Banner transfer rules
| Item | Transfers through Banner? | Notes |
|---|---|---|
| Amber Medallion | No | Applies only to the Banner itself. |
| Knockback Hammer | Yes | The knockback effect is shared. |
| Devil's Fist | Needs testing | Attack-speed effect has a max stack of 1. |
| Light Speed Feather | Needs testing | Attack-speed effect appears to stack. |
| Tower Boots | Needs testing | Sets movement speed to 0, but Banner transfer behavior should be confirmed before adding. |
Testing needed
- Confirm whether Tower Boots can be transferred by Banner.
- Confirm whether Devil's Fist shared by Banner counts against the target unit's max stack.
- Confirm whether Light Speed Feather stacks when applied through multiple Banners.
- Confirm whether Beads changes max-stack behavior when equipped on the Banner, the target unit, or both.
