Magma Spumes can be found swimming in pools of lava. They will hop up from the lava to spit out a fireball towards you.
How to Defeat
Since this enemy is found in lava, you cannot beat them with conventional means. Instead you’ll have to rely on projectile weapons such as Bombs or roll into them with the giant eyeball.
If you need to get close to them, their fireballs can be deflected using your shield (as long as it’s not made of wood). You can also use your sword to hit the fireballs, causing them to dissipate.
