New weapons, new classes and subclasses

I want to propose new classes for consideration and possibly for adding to the game, or using them as subclasses of existing classes. Also, a new weapon and a shield.

1.

-Alchemist
Archetype: Master of transmutation and unstable reactions.

Main attributes: Intelligence + Dexterity.

Unique mechanics:

Potion Creation: Instead of standard vials, the Alchemist can combine ingredients obtained from monsters to create powerful temporary effects, ranging from mass control (such as petrification) to explosive environmental transformations.

Chemical Weapons: Uses weapons, old ancient books with spells and recipes, distillers, or syringe guns that inflict complex conditions, such as turning enemies into unstable bombs that explode upon death.

Deep Crafting Synergy: Passive skills can enhance crafting effects throughout the playthrough, making it unique for those who enjoy deep customization.

2.

-Spiritist
Archetype: A medium who interacts with spirits and otherworldly forces.

Primary attributes: Intelligence + Dexterity.

Unique mechanics:

Spirit Summoning and Fusions: Unlike Necromancy, which summons physical minions, the Spiritist summons spirits that grant effect auras or temporary abilities. Can temporarily fuse with a spirit, taking on its form and abilities.

Possession mechanics: Can possess enemies to use their bodies for attacks or to pass through obstacles.

Ancestral energy management: A resource that is replenished by kills or rituals, and is spent on powerful spirit-related abilities

- Weapons and clothing

3.1
Huge, massive brass knuckles, half a man's height, if held in the hands, will practically reach the ground, with metal spikes or dragon teeth, for example. So big that they look like one stool in each hand. You can add a warrior to them, or build a new melee class around them, with the highest attack speed and cold combos, so that enemies fly like icicles, which would make even "King of the Night" jealous.

3.2
A shield with the head of a Gorgon Medusa, which would cause enemies to turn to stone for a short time when they were protected or damaged, and would crumble into small stones or sand when attacked or dealt additional damage.
