Ichthyosaurus Offspring (I’ll call him saurus as a reference to make things easier on me) is the second boss you’ll encounter, and this is where the game makes a real big jump in difficulty compared to the first boss.
Ichthyosaurus Offspring Boss Fight Guide
The arena is made up of a big circle-ish sand area, completely open with no cover at all!
- Weakness: Corrosion To Strip The Armor, Fire To Drain The Health.
- Weakspot: Head In Phase 1 (Although The Hitbox Seems Incredibly Wonky And Shooting Towards The Throat Seems More Consistent). Tail In Phase 2.
Phase #1
Laser beam: The boss will always start the fight using this attack. He’ll come out the sand with his head sticking out and tilt his head towards the left or right and start firing a laser beam in the direction of the player. Avoiding this attack can be real tricky BUT there’s 2 ways to do it. 1st way is to stand still until the boss tilts his head, then circling the other direction dodging when nescessary for the little boost in distance the dodge gives you. 2nd way is to keep circling the boss in a specific direction, if the boss tilts his head the other way – GOOD! If not and he tilts his head towards you then quickly dodge through the laser attack as soon as it starts to take as little damage as possible.
Slam attack: The boss will melee slam the player and will only do this if you come too close to the boss. Avoiding this attack is just a matter of staying away a comfortable amount from the boss.
When you get his armor down to about 50% the boss will submerge into the sand and 2 minions will spawn in the arena that you have to kill for the boss to reappear. These can be either fire lizards or hyenas. I’ve never had the minions be a mix and I’ve always had the hyenas spawn first, then the lizards (sometimes skipping the lizards entirely with enough damage done to the boss). After the minions are killed the boss wil emerge from the sand again and phase 2 starts.
Phase #2
The boss will be emerged from the sand, this time with only his tail visible. A few new attacks will be added to his roster;
Poison bombs: The boss will lob a series of poison bombs into the air that will explode into a poison AoE field when they hit the ground. Both the explosion and the damage AoE field can hurt the player. The trick to avoiding this attack is having either a good AoE weapon OR a rapid fire weapon and shooting the orbs before they have a chance to hit the ground. If some orbs got through and hit the ground you’ll have to be wary of your positioning, however the AoE damage fields will disappear after a short while (+/- 10 seconds).
Tail Shockwave: The boss will whip this tail onto the ground creating a shockwave of sand going towards the player. This attack can easily be avoided by jumping over it. When enough damage has been done (30-40% HP remaining) he’ll do 3 shockwaves one after the other instead of 1. Jumping over each one does the trick. IF you get caught by the first shockwave however it’s incredibly difficult to recover and you’ll most likely end up eating all 3 shockwaves which can easily put you in a dangerous low HP situation.
Note: I’ve had the boss swap from phase 2 to phase 1 ONCE in my multiple runs which seemed more of a bug rather than an intended game mechanic, just be aware that this CAN happen.
The most dangerous attack this boss can do has got to be the laser beam. The hitbox for the laser and his weakspot are so wonky that I’ve gotten killed by his laser multiple times while I was on the complete opposite side of the laser!
