 ### Condition Types
+
+**Flag Conditions:**
 - `flag:name` - Flag is set
 - `!flag:name` - Flag not set  
-- `var:name` - Variable exists
-- `!var:name` - Variable doesn't exist
-- `field>=value` - Comparison operators: `>=`, `<=`, `>`, `<`, `==`, `!=`
-- `field&0x01` - Bitwise AND
+
+**Variable Conditions:**
+- `var:name` - Variable exists and is non-zero
+- `!var:name` - Variable doesn't exist or is zero
+
+**Version Conditions:**
+- `version>=562` - Version comparisons
+- `version<1200` - Supports `>=`, `<=`, `>`, `<`
+
+**Value Comparisons:**
+- `field>=value` - Numeric comparisons
+- `field!=0` - Supports `>=`, `<=`, `>`, `<`, `==`, `!=`
+
+**String Length:**
+- `name!>5` - String longer than 5 chars
+- `name!<=100` - String 100 chars or less
+- Supports `!>`, `!<`, `!>=`, `!<=`, `!=`
+
+**Bitwise Operations:**
+- `field&0x01` - Bitwise AND with hex value
+
+**Complex Logic:**
+- `cond1,cond2` - OR logic (comma-separated)
+- `cond1&cond2` - AND logic (ampersand)
+- `version>=562&level>10` - Multiple conditions
+
+**Array Context:**
+- `item_type_%i!=0` - `%i` substitutes current array index
