When you Activate the javelin, your command makes the carvings crackle with electricity. You then hurl the javelin. It shatters immediately after leaving your hand and unleashes its magic as a 4th-level Lightning Bolt originating from your space.
The bolt deals 5d12 electricity damage and has a DC 25 basic reflex save.
