Quick answer: Initially, only two accessory slots are available. Learn Boundless Capacity at a bell; its four ranks grant one slot apiece, bringing the total to six.
How many accessory slots there are
In Phantom Blade Zero, press Esc, select CHARACTER, then open Equip to locate your accessories. The ACCESSORIES section is underneath Main Weapons, Phantom Edges, and Medicines. Its two rows contain three slots each, making six slots altogether. Two are available from the beginning; a lock icon marks each slot that needs its corresponding level trained.
How to train Boundless Capacity
Boundless Capacity levels and costs
Each of the four levels costs more Remnant Dust than the one before it and adds one slot, taking you from two slots to six. The full abilities list has every other node and its cost.
| Level | Effect | Remnant Dust | Open slots after training |
|---|---|---|---|
| Boundless Capacity Lv. 1 | “Adds 1 accessory slot.” | 10,000 | 3 |
| Boundless Capacity Lv. 2 | “Adds 1 accessory slot.” | 40,000 | 4 |
| Boundless Capacity Lv. 3 | “Adds 1 accessory slot.” | 65,000 | 5 |
| Boundless Capacity Lv. 4 | “Adds 1 accessory slot.” | 80,000 | 6 |
What Lv. 2 needs
Boundless Capacity Lv. 2 is the central node in the second row, Sha-Chi Amber. Its card says “Adds 1 accessory slot.” and the preview highlights the fourth slot alongside three filled ones. Training costs 40,000 Remnant Dust and has two additional requirements:
- “Prerequisite skill required”
- “Requires 2 Sha-Chi Amber”
Collect Sha-Chi Amber Shards to obtain Sha-Chi Amber. The button displays “TRAINING REQUIREMENTS NOT MET” until you satisfy both requirements.
Using the new slot
To confirm Lv. 1 took effect, open Character > Equip. The ACCESSORIES grid should have three available slots and three locked ones.
If you obtain an accessory from a reward or shop, its card’s slot selector includes the vacant third position and the prompt “Equip accessory to empty slot.”
