The boss itself is pretty easy but it's the spaceship that adds additional mechanics. There are three turrets located in the room which you need to utilize to deal with the spaceship.
The spaceship is located to the left of the turrets. It can move forward/backward and sideways.
If it moves forward, it can fire a whole bunch of rockets on the ground, making the fight a lot harder.
However, if you have someone on the middle turret (where the spaceship appears initially) and just click the turret whenever the spaceship gets close, it will push the spaceship back (It will emote – Ship targeting system disrupted! Target lock reset!) This cause the ship to use exclusively long ranged missile, which you can avoid as there is a red circle on the ground letting you know where the missile will land.
The actual boss itself has several abilities, the most prominent of which is the random stun he like to place on party members
- Stun: this ability is either called charging electro dart barrage or electro dart. The stun doesn't last for long (~3 seconds).
- Flame Sweep: This is 360 degree AoE that can be and should be interrupted.
- Grapple: he likes to use grapple to pull the tank back if he/she gets too far away.
Overall, the boss doesn't hit too hard; if someone is on top of the turrets and deals with the spaceship then it can be a very trivial fight.
Hardmode: Exact same mechanics as normal mode except you need to be on top of the turret to shoot the spaceship back. Eventually the spaceship will be destroyed and only the boss is fight. Pretty easy fight even on hardmode.
Drops: He drops the Tionese boots. Here is the screenshot of the tank heavy armor version.
