Make a strong and fun league starter build for the game path of exile. The build should be able to map very fast and clear packs of monsters efficiently. I would like to play Occultist ascendancy because I want to switch to Arakaalis Fang later when I aquire enough currency.
Certainly! A strong and fun league starter build using the Occultist ascendancy, which can transition well into using **Arakaali's Fang**, is a **Bane Occultist** build. This build focuses on the Bane skill for clearing maps efficiently and can scale well into endgame content. Here’s a detailed breakdown:

### Bane Occultist Build

#### Key Skills
- **Bane**: This is your primary skill for dealing damage over time.
- **Despair**: This curse enhances the damage dealt by your Bane skill.
- **Wither**: This skill increases the damage taken by enemies and also helps with scaling your damage.
- **Contagion**: This skill helps spread your poison and is great for clearing packs.
- **Body Swap**: Optional, but can be fun for mobility if you want to use it.

#### Ascendancy
1. **Profane Bloom**: This is your main source of clearing power. It causes your curses to explode, dealing damage to nearby enemies.
2. **Malediction**: This allows you to curse an additional enemy and gives you increased damage.
3. **Void Beacon**: This reduces enemy damage and increases your damage against them.
4. **Whispers of Death**: This provides a large boost to your damage and survivability through life leech.

#### Passive Skill Tree
- Focus on:
  - **Life**: Ensure you have a good life pool
This build starts with a Warrior and an Occultist. The Warrior should be equipped with a two-handed axe and a shield, and the Occultist with an Arcane staff and a dark aura orb. The first two skills for the Warrior should be Bash and Shield Wall, and the first two skills for the Occultist should be Dark Pact and Arcane Flux. After that, the build should focus on map clearing skills. For the Warrior, these would include Avenger's Shield, Power Word: Shield, and Berserker's Rage. For the Occultist, these would include Occultist's Mark, Dark Pact, and Occultist's Initiation. The build should also include skills that increase the speed of mapping, such as Power Word: Shield and Avenger's Shield. Finally, the build should end with Arakaalis Fang, which increases the damage of the build exponentially.
