Buy RS3 Flarefrost boots
Flarefrost boots are tier 90 ranged boots in RuneScape 3. They are power armour, so they boost your ranged damage in combat. You need level 90 Defence to wear them. They also give a prayer bonus of 2.
These boots are an upgrade of glaiven boots. They are made by adding two glaiven wing-tips to a pair of glaiven boots. The wing-tips drop from creatures in the Dragonkin Laboratory and from rune dragons. Emberkeen boots are the melee version, and hailfire boots are the mage version.
Flarefrost boots degrade as you fight. They last for 100,000 hits of combat, then they turn back into glaiven boots. You can use a glaiven wing-tip on the boots to recharge them by 50 percent. Once you equip the boots, they become untradeable for good, even if you charge them back to full.
These boots are a strong pick for high level rangers. They fit well with other tier 90 ranged gear for bossing and slayer tasks. This is a members only item. It weighs 1.5 kg and cannot be stacked.
