Dragonfly

The Dragonfly is a giant from the Reign of Giants DLC. It will appear in the Summer and is apparently attracted by Birchnuts. It takes 58 hits with a Spear,47 hits with a Battle Spear, 20 Blow Darts, 33 hits with a Ham Bat, 47 hits with a Bat Bat and 30 hits from a Dark Sword to be killed. One of its abilities is spitting lava, which it will casually spit on various objects while it is in its calm state in order to produce Ash, which it eats. If attacked or if the player stays too close for too long, it enters an 'enraged mode' where it will light everything in it's path on fire. During rain, this mode lasts less time, and if frozen it will immediately return to a calm state.

It drops Scalemail and 8 meat.

Attack Pattern
In close range, he will do a large area of effect attack after squeaking. There is a 3 hit space between attacks, 2 if you wish to escape without being hit. After being left alone for a while, the dragonfly will calm down and revert to its green form. When attacked in the green form, it can chain two of these attacks together in a short span.

It also has a short range swipe, but it is rarely used.

Trivia

 * The name and appearance of the Dragonfly is a tongue-in-cheek portmanteau of the words "dragon" and "fly".
 * When enraged it stomps, then causes fire to fly around it.
