Rift worlds and bosses

Rifts are Polyworld's monster dungeons, opened at the King's statue on the plaza. Every rift belongs to one of six worlds: its monsters fight with that world's element, each floor ends with a guardian, and a boss waits at the bottom. Higher tiers drop finer gear, and the tiers never end.
