Why it worked

Every spell set Blaze, and landing one on a burning target upgraded it — Pillar of Flame for double damage, Conflagration to spread. Pyroclasm bounced from champion to champion and sped up with each bounce, so a grouped team caught it several times over. Liandry's burn sat on all of it at once.
