 * Rag - Can be soaked in chloroform to knock out targets

 * Usage:
 * 1. Hold chloroform bottle, rag in offhand, right-click → rag becomes wet
 * 2. Hold wet rag, right-click target → apply chloroform effect
 * 3. Wet rag evaporates over time (configurable)
 *
 * Effects on target:
 * - Slowness 127 (cannot move)
 * - Blindness
