- [x] `paralyze` - Reduces speed by 50%, 25% action failure chance βœ…
- [x] `sleep` - Prevents actions for 1-3 turns, wake on damage βœ…
- [x] `confuse` - 33% self-damage chance, lasts 2-5 turns βœ…
- [x] Major status conflicts - Only one major status at a time βœ…
- [x] Confusion compatibility - Can stack with other statuses βœ…

### 3. Switching System βœ… **COMPLETED**
- [x] **Setup**: Define switch actions and piclet roster management βœ…
- [x] **Test**: Write tests for switch mechanics and entry hazards βœ…
- [x] **Implement**: Add switch action processing βœ…
- [x] **Integrate**: Connect entry hazards to switching βœ…
- [x] **Verify**: Test complete switching flow βœ…

**Switch Mechanics Implemented:**
- [x] Switch action processing βœ…
- [x] Entry hazard application on switch-in (spikes, toxic spikes) βœ…
- [x] Switch-in/switch-out ability triggers (onSwitchIn, onSwitchOut) βœ…
