CreatureVariant

The X-Ichthyosaurus is a variant of the Ichthyosaurus, a carnivorous aquatic creature from Genesis: Part 1. It features a slight melee damage increase and reduced health compared to the base species. This variant is tamed passively and used primarily in underwater combat or for breeding with other X-variants.
It can be airlifted by Quetzal or Karkinos for fast deployment.

The X-Ichthyosaurus is tamed passively by feeding it while it is alive. The best food is Simple Kibble, which provides the fastest taming effectiveness. Raw Mutton also works well, offering nearly half the affinity of Simple Kibble.
Taming takes about 3 minutes with Simple Kibble at level 224. Use the calculator below for your settings.

The X-Ichthyosaurus has a +120% vulnerability to Instant HurtDinos, making it take significantly more damage from such sources. It is also highly weak to spike walls, taking +100% more damage. Conversely, it is completely immune to Mining Drill Harvest damage, taking -100% damage from it. Melee attacks with impact effects are 50% less effective against it. Focus on exploiting its weaknesses with explosive or spike-based defenses.
The head has a 1.5× damage multiplier, making it the optimal target for faster knockouts or kills. Focus attacks on the head when possible.
