Wild
This wasteland’s full of surprises, and not exactly the good kind. There’s something out here that looks like Fasolasuchus, if those proto-crocs could swim through sand like water…
These beasts might pop up suddenly to ambush you, or swim around you fast enough to catch you in a sand-whirlpool. I can't stress enough how dangerous this deathtrap can be! Plus their tails are strong enough to whip up sand to blind predators and prey alike.
If you can help it, I recommend staying clear of those spikes. I think they’ve got acid glands at the base of their spiny fins, and in their mouths as well. Their caustic bite seems to melt through the thickest hide.
Domesticated
One of these monster sand-swimmers would make a great mount, but good luck slowing down something that can shrug off most narcotics. You could try softening one up with explosives, grabbing a spike, and steering it into a rock… But you’d have to be a bit mental to try.
I imagine the adrenaline junkies able to tame a Fasolasuchus would earn themselves a formidable ride through these scorching sands. They seem to have adapted to fighting larger prey, so I'd advise any faso-rider to steer clear of packs of smaller creatures that can swarm over its defenses.
Type in values of a wild creature to see on which stats it's emphasized. Green values on a high-level creature are very good for breeding. If you have already tamed your creature you can try to recover the breeding stats with an external tool.[1]
Fasolasuchus
The stat-calculator does not work in the mobile-view, see here for alternatives: Apps
Note that after the creature is tamed it gets bonuses on some stats depending on the taming effectiveness. This makes it hard to retrieve the levels on a tamed creature, so this tool is only for wild ones, but gives a first impression, how well the stats are distributed.
This attacks applies Armor Corrode to the target, which increases the damage that it takes for 10 seconds by 2.5%, this effect can be stack up to 10 times, decreasing the target's damage resistance down to 25%, timer resets with each bite.
Can be used every 0.89s by both a rider and the AI.
Once burried the Fasolasuchus can move freely under the ground, but it constantly consumes Stamina while in movement.
If the Fasolasuchus don't moves for 3 seconds while buried it will camouflage as a sand pile and it will recover Stamina, but also its rider will start to lose Oxygen. It can only be seen in this state by players of the same tribe.
If the Fasolasuchus collides with a rock while it is digging under the ground, it will only collect Flint from the rock.
The Fasolasuchus starts moving in circles around a small area continuously, making a little sandstorm in the progress.
Every player and creature inside that area will reduce its Movement Speed, players also will get dismounted of their mounts and the flying creatures will be shot down from the sky.
If the Fasolasuchus loses 10% or more of its total Health this action will be cancelled.
Quicksand
Only while Sandstorm is active
The Fasolasuchus converts the ground inside the Sandstorm area into quicksand.
The targets trapped inside the quicksand starts to slowly descend until they are completely buried by the sand, after they are completely buried they will receive damage to then come back to the surface.
The damage that this action does not scales with the Melee Damage, however, it is a percentage damage and it depends of both the Health and the drag weight of the targets trapped.
Passive
Venomous Spikes
Similar to the primary attack effect, if the Fasolasuchus receives damage from melee attacks, the aggresor will get the Armor Corrode effect. Also the aggresor will always receive 4 damage with every hit it does to the Fasolasuchus.
Bury
The Fasolasuchus has a bury option on its wheel menu, after ordering this action the Fasolasuchus buries itself, though buried wild Fasolasuchus are visible through the sand/dirt that they dig up, tamed Fasolasuchus are invisible to non-allied players.
Taming
The Fasolasuchus has a rather unique process to KO it; you have to wait until the Fasolasuchus buries itself and either throw a grenade at the mound or place C4 on top of the mound and detonate it. This will cause the Fasolasuchus to emerge in a disoriented state, at which point the player can interact with it and ride it. When riding, the player must 'drive' the Fasolasuchus into rocks to gain torpidity and ensure the control bar does not reduce to 0. Successfully driving it into a rock-based resource will fully restore the control bar. Metal, crystal, and raw salt nodes will cause more torpidity compared to standard rocks. While it can also hit trees, this will not induce torpor or reset the control bar, and should generally be avoided when possible. After it collides with something, there will be a brief period where it will be uncontrollable as it either turns clockwise or counter-clockwise; if it continues to hit things in this state, you are at its mercy as you will not be able to control it. This process can take a very long time for a high-level Fasolasuchus, and you may find yourself partially across the map in some cases.
If the Fasolasuchus goes airborne by falling off a cliff or the control bar reaches 0, you player will be dismounted, and you will need to lose its aggro until it buries itself again. However, there is a little leeway in this mechanic and you may stay mounted when falling off a small ledge. If you do get dismounted, their torpor drain is slow so you will not lose much KO progression.
Once knocked out, it can be tamed as normal by feeding it its preferred food.
Due to the plethora of metal nodes on the surface region of Aberration, taming a Fasolasuchus there is much less time-consuming compared to Scorched Earth. However, it's advised to wait until a day where it is 10% day/90% night (days ending in 7, 8, and 9). Wait until after 05:30, at which point Nameless and Reapers will no longer spawn. From there, you have free reign to knock out the Fasola without much interference which shouldn't take more than 2 in-game hours in most cases. However, you will want to ensure that you are out of the surface region by 11:00 on those days. After it's knocked out, you can give it the required taming food and leave render distance, then return during the next night cycle which will start around 14:30; as long as it's not rendered during the day, it will not take any damage. Nameless/Reapers will not spawn until 17:30 so you have time to do any maintenance on the tame, such as giving narcotics. Once tamed, you can simply Cryopod the Fasola to keep it safe and leave the area. Due to the immense damage that Reapers do, it's best to wait until the aforementioned timeframes to where they will not spawn in order to secure your new tame.
Combat
Utility
Roles
Combatant: The Fasolasuchus has a great combat stats, so it can be used as a combat mount (Level up Health, Stamina and Damage).
Combat Support: The Fasolasuchus has interesting abilities that can be helpful on big fights such as reduce the target's damage resistance or prevent enemies from attacking (Level up Health and Damage).
Big Creatures Killer: The Fasolasuchus sandstorm mechanic allows it to trap and damage targets, this is specially efective against big creatures due to the fact that this mechanic effect scales with the drag weight of the targets, but not with the Fasolasuchus' Melee Damage stat (Level up Health and Stamina).
Farmer: While the Fasolasuchus is digging under the ground and collides with a rock it harvest it and only collects Flint from there, making it the only creature in the entire game that can only collets flint from rocks, it is also good at gathering Meat and Hide (Level up Weight and Damage).
Dune Explorer: The relatively fast speed of the Fasolasuchus while digging under the ground along with the fact that medium-sized creatures that inhabit the dunes such as Mantis or Arthroplueras do not attack it makes it an excellent option to scout the dunes in search of Deathworms and Desert Loot Crates (Level up Health, Stamina and Weight).
Land Leveler: While it is digging underground, the Fasolasuchus breaks rocks and trees by just passing under them, this is a good option to free the land before start building there.
