Hailfire boots degrade for 100,000 hits of combat before reverting to ragefire boots. On death in the Wilderness, they are dropped as degraded hailfire boots. Using a ragefire gland on a pair of Hailfire boots will recharge it by 50%. Once equipped, the boots become permanently untradeable, even if they are recharged to 100%.
Creating hailfire boots yields a profit of 4,855,990 coins.
