Wildfires and Hovering Infernos

I think that the design for the Wildfire/Hovering Inferno blaze variant is interesting, and I believe that the addition of shields around it is what makes it as interesting as it is. I propose that there be new Blaze variants known as Wildfires. These would be slightly stronger versions of Blazes, with the main difference being the shields around them. Four floating shields would surround these flaming creatures that would block incoming projectiles when in "defense mode". Wildfires would go into defense mode when not attacking. However, these shields could be taken down if enough snowballs are thrown at the shields, disabling the shields for a short period. I also propose a miniboss version of the Wildfires: the Hovering Inferno. It would be a larger version of the Wildfires, with more health and attack power. It would be able to charge up a stronger fireball to launch at the player, as well. The Hovering Inferno would be like the Elder Guardian of the Nether Fortress. Defeating it would reward the player with a special Infernal Shield that would send a firey shockwave out when activated or disabled by an axe, knocking enemies away. However, it can only be used for a certain amount of time and has a cooldown when either the time runs out or the user puts the shield back down.
