Here is a Tower of Fantasy Ruin E-03 Walkthrough and tips to defeat the Greenfly boss.

Okay, so this ruin is purely a boss battle. Head up the platform, and then you come across a boss called Green bird. The boss is a hybrid of a few bosses we have encountered in the ruins so far, along with its own boss special tactic.

The main skills you need to watch for are:
Triple Swipe - The boss rears backwards, and its melee weapon glows orange. Dodge it, and you can avoid the triple swipes the boss does.

Air Dive - Greenbird goes into the air, and either goes back to the middle of the room or tries to crush you. Either way, change position to dodge the landing.

Gatling Gun - The boss revs up its Gatling gun on its left arm and fires rounds at you. Keep moving to avoid the oncoming rounds, or you can use the turrets around the battlefield as cover.

Red Circle Slam - The boss can go into the air and drop down its body onto the floor. If the move is highlighted in a red circle, then you need to back out. The red circle only indicates where the boss lands and not the extra blast on the outside of the ring. Stay as far back as you can from the red circle and then some more to ensure you don’t get hit.

Red Lazers - The boss flies back into the middle of the room and floats. Red beams then descend around the player fairly fast over the course of a few seconds. The strategy here is to run round in circles as the boss tries to put the lasers where you would be if you were to run in a straight line.

Missile Strike - On lower HPs the boss calls in a giant missile strike on the battlefield. This has a very large radius; you will need to use your three dashes to escape its blast radius.

Turrets Online - When Greenfly reaches its second bar, it can turn on the turrets around the battlefield. These tend to take a while to charge up but become more active the closer the boss is to death. The general rule of thumb is to keep on your toes to avoid getting hit the best you can. The damage isn’t all too bad, but they can rack up and kill you, so you will need some decent food like purple quality healing meals.
