From Dota 2 Wiki
|A rather typical spear that can sometimes pierce through an enemy's armor when used to attack.|
- The proc chances of Pierce from multiple Javelins work fully independently from each other.
- This means that two of them can proc on the same attack and both deal their damage.
- Also stacks with Pierce of Monkey King Bar.
- The damage can be reduced with e.g. Enfeeble or Static Link.
- Adds an average of 25 magical damage to every attack.
- Pierce uses pseudo-random distribution.
- Attacks which proc Pierce cannot miss.
