When you get to the fourth area (Winter Horns) you no doubt know how to improve your copying skills. However, there is a way to make these abilities even more powerful – by tracking down the Tier 3 upgrades for each ability. Here’s where to find the Dragonfire Skill Upgrade in Kirby and the Forgotten Land.
Go to level 4-3 (Windy, Freezing Seas) first. You have to progress through the stage until you reach the wind tunnel, which will constantly push you forward. There are a few Hot Head enemies along the way, and you’ll need to grab a fire ability to unlock the blueprint. As you continue there will be a scissor lift that is frozen. Thaw it, go into Mouthful mode and move the lift to the right – there’s a chest at the very top that contains the Dragon Fire upgrade.
Dragon Fire requires three Rare Stones and some Star Coins to upgrade your skill. It allows Kirby to fire a continuous stream of fire that quickly deals damage to enemies. Your meteor attack turns into a kite jump. Give Kirby the ability to glide while descending. The distance traveled is also increased, offering great mobility and speed when needed.
