Arnold

Arnold is a gunsmith who crafts firearms, drones and other similar tech, he always works in the Fort doing his research.

Occasionally makes weapons for Jake but only if Jake gives what he needs.

History
Before the system he worked on inventing stuff, After the Tutorial, He worked at the Fort under Phillip making guns for everyone, Later when Jake visited the Fort to get immigrants, Phillip introduced Arnold to Jake.

After the Fort was integrated with Haven, Phillip still continued to be the leader of sorts for the fort, Which now houses hub of smithies making guns and other equipment.

He made the injectors that helped Jake kill the D-Grade Mushroom Monster in the Biodome.

At somepoint after evolving his profession, He was and blessed by an unknown God, He was not looking forward to such meeting again as he was affected by the aura of the God.

Later inspecting one of the weapons transmuted by Jake which was sold by Miranda and Lillian, Wanting to make bombs from Jake's destructive mana, Arnold insisted to Phillip on wanting to speak on this matter with Jake, Which Phillip informed to Miranda,

Hearing this Jake came to the Fort, The moment he noticed Jake he asked him to fill the bombs with his Mana, But Jake wanted something in return for which arnold decided to make him the Nanoblade, Letting Jake inspect the blade he told him to choose the blade so he could make handle more suited for Humans, Jake joked whether he was making them for Robots for which Arnold seriously nodded and said excitedly about how amazing are sword-wielding robots, After charging those bombs he received his Nanoblade and 10 of the bombs charged with his own mana, With that Jake left for Dungeon diving.

On their next meeting Arnold inquired Jake about the effectiveness of Bombs, As it turned out Arnold tests his bombs by dropping them on D-Grades and had killed several D-Grades with Jake's mana charged bombs, During his tests it was realized that if low leveled person uses the same bombs, The effectiveness drastically decreases, Due to the unstable nature of Jake's affinity he had to resort to fire affinity mana which is more stable.

Jake having finally stopped being questioned asked Arnold for something in return for the Altmar Census Golem Corpse, For which Arnold gave him better Gloves which he had made after observing stability from the bombs infused with Jake's affinity, He promised benefits on research on the Golem and even agreed to upgrade the Nanoblade, And Jake left once again.

When Sultan came to the Fort, He first visited Arnold before visiting Jake.

A while later Jake visited Arnold, finding him observing the golem parts with a microscope, Jake helped him by using mana constructs to show him the circuit board as Arnold had only 1700 perception compared to Jake's 6000, Then he asked for his upgraded Nanoblade.

Later Arnold also joined the Treasure Hunt, Using his drones to hunt for treasures and occasionally helping Haven related parties to navigate each other.
