Rune Song special attack and features

• Special attack "Song Trail" (hold right-click, then release): sends a damaging trail toward the cursor that passes through walls. It is 2–6 tiles long depending on charge time, deals up to 3× the sword's damage, and has a 25% chance to stun enemies for 2 seconds.
• Melee hits restore health.
• Melee hits have a chance to grant +50% melee attack speed for 2 seconds.
• It has no durability, so it never breaks (but it cannot be reinforced).
• The earliest you can make it is after breaking the Great Wall, because the Chipped Blade is in Azeos' Wilderness. The Broken Handle can drop early from The Hive Mother.
