This ability always takes the form **[MELTA X]**. Each time a model makes an attack with a **[MELTA]** weapon, if the target unit was within half range of that weapon in the Select Targets step, until the attacking unit’s attacks have been resolved, add **X** to that weapon’s **D** characteristic. 
***Example:** A model targets a unit that is within half range of a **[MELTA 2]** weapon with a **D** characteristic of D6. While resolving those attacks, that weapon has a **D** characteristic of **D6+2**.
