Kog'Maw Ability (LoL): Living Artillery

Kog'Maw fires a living artillery shell at a great distance. After a 0.6 second delay, the artillery falls dealing 100 / 140 / 180 (+35% of ability power) (+0.65 per bonus attack damage) magic damage and reveals targets for 2 seconds. Each subsequent Living Artillery in the next 8 seconds costs 40 additional mana (max 400).

Living Artillery deals deals 150% damage to enemies approching 40% health and 200% to enemies between below 25% health.
