## Mundane (Common, 5–50 gp)
- **Iron Manacles (10 gp):** Restrains wrists. A restrained caster can’t perform most somatic components.
- **Leather Muzzle / Iron Gag (5–15 gp):** Prevents speech; no verbal components.
- **Heavy Net (1 gp):** On a hit, restrains. Requires a DC 10–15 Strength check to escape. Cheap and effective.
- **Component Pouch Confiscation:** Take away focus, wands, holy symbols, and pouches. Many casters are crippled without them.
---
## Uncommon (50–500 gp)
- **Magebinder Rope:** Hemp rope braided with silver thread and runes. DC 18 Strength to break. While bound, caster must succeed on DC 15 Arcana check to cast any spell.
- **Rune-etched Shackles:** Simple runes etched into cold iron manacles; impose disadvantage on spell attack rolls and concentration checks.
- **Collar of Silence:** Worn around neck; once locked, the wearer is under a continuous _silence_ effect.
---
## Rare (500–5,000 gp)
- **Dimensional Shackles (DMG, Very Rare, ~5,000 gp):** Prevent teleportation and planar travel. DC 30 Strength to break.
- **Mage’s Bane Shackles:** Disadvantage on all spellcasting ability checks and saving throws. Cantrips require a DC 15 concentration check or fail.
- **Glyph-linked Shackles:** If a spell is cast while wearing them, a _hold person_ glyph automatically triggers (DC 15 Wisdom save or be paralyzed).
---
## Very Rare to Legendary (10,000+ gp)
- **Antimagic Shackles:** Projects a 5-ft radius antimagic field around the wearer. Only crafted by archmages or inquisitors.
- **Chains of Binding Will:** Legendary fiend-forged chains. Suppress all spellcasting and magical abilities. Breaking them requires a wish or divine intervention.
- **Nullstone Cell (facility upgrade):** Entire cell carved from meteoric nullstone. Inside, no magic functions—like a natural antimagic field.
---
## Optional Add-Ons
- **Sleep Poisons & Smoke Bombs:** Used to drop a caster before restraints can go on.
- **Mage-Slayer Guards:** Elite wardens with the _Mage Slayer_ feat to interrupt casting.
- **Anti-Teleport Runes (1,000 gp per room):** Wards a chamber against _misty step_, _dimension door_, or similar effects.

### DM Tip
Arresting casters should _never_ be just one tool—it’s about **layers**.
Example: _Net → gag → rune shackles → anti-magic cell._
