# 🎲 Taking Actions with the D4 Dice Pool
Most actions in this system are resolved by rolling a **pool of d4s**, determined by your character’s Aspects and the situation.
Each **Aspect** provides a virtual dice pool equal to its value. Your capacity to act is limited during your turn by increasing your **🌀 Action Load** as you take actions. This Action Load typically resets to a negative value at the start of your turn.
The d4s you roll represent **effort, attention, and precision**. The more dice you spend, the more effective you are but the harder it is to keep acting.

## ⚙️ Turn Structure and Action Load
At the **start of your turn**:
- Reset your **Action Load** to **0 - your Action Point Bonus**
When you take an action:
1. **Identify the relevant Aspect**
This depends on what you're trying to do—see the [Aspect Table](rules:aspect_table).
2. **Check if the action is allowed**
Subtract your current **Action Load** from the relevant **Aspect**.
- If the result is **greater than 0**, you may take the action.
- If the result is **0 or less**, you cannot take that action until your Load is reduced.
3. **Determine your Net Advantage**
Add up all sources of **Advantage** and **Disadvantage** to find your **Net Advantage** for the roll.
4. **Calculate how many d4s to roll**
- Start with: `Aspect – max(0, Action Load)`
- Add or subtract 1d4 for each point of **Net Advantage**
- You always roll **at least 1d4**
- Add any extra dice (such as a weapon's **1d8**) as required by the action
5. **Roll and resolve the action**
Apply the outcome based on your total roll and the action’s effect.
6. **Increase your Action Load**
Add the action's **Cost** (usually 1 or more) to your **Action Load**.
You can keep acting as long as your **Aspect − Action Load** remains **greater than zero** and meets the action’s cost.
Instead of resetting Action Load at the beginning of a creature's **turn**, an alternative is to reset *everyone's* Action Load to zero at the beginning of each **round**. This will affect when and by how much creatures (characters, NPCs, and monsters) can take reactions.
We will definitely be playtesting this idea.

## ⚖️ Calculating Net Advantage
### What is Advantage and Disadvantage?
**Advantage** is when something boosts your action. It might be an ability you have from a Feature, because of something in the environment, a friend assisting you, or something else.
**Disadvantage** is when something is hindering your action.
For each instance of Advantage that you have for a particular action, you can add a d4 to your Action Roll.
For each instance of Disadvantage that you have for a particular action, you subtract a d4 from your Action Roll.
Advantage and Disadvantage stack, unlike in D&D 5e and similar systems. This means you can get multiple d4s added to your rolls, but it also means that you could get multiple d4s removed from your rolls.
🔁 **Note:** You can only gain **Advantage** or **Disadvantage** from a single source **once per action**.
Multiple effects from the **same ability**, feature, or condition do **not** stack.
📘 **Example:** If two allies both use the *“Watch My Back”* feature to give you Advantage on your next roll, you still only gain **+1d4**—because both effects come from the same source.
Before making an Aspect Check or other Aspect-based roll, but after determining if the action can be taken, calculate the **Net Advantage**. This is the number of d4s you add to or subtract from your roll.
Example: A character is trying to disable a trap so the game master has them make a Finesse Aspect Check. Their Finesse value is 4 and their Action Load is 0 - the d4 pool is 4. This trap is in a darkly lit dungeon which gives Disadvantage - the d4 pool is now 3. One of the other characters helps by holding a torch, giving Advantage - the d4 pool is now back to 4. Another character assists by peering over their shoulder and giving advice, granting another advantage - the pool is now 5. The player will roll 5d4.

## 🎲 Resolving the Dice Roll
🧮 Add all dice together and declare the total.
The GM then either:
- Subtracts the **target’s Evasion** (for attacks)
→ The **remainder becomes damage dealt**
- Compares the total to a **Difficulty Class (DC)**
→ The **action succeeds** if the total **meets or beats** the DC
📘 **Example:**
Your Finesse is 6 and your Action Load is 2. You want to use a dagger (1d4 damage).
You roll 6 − 2 = **4d4** + **1d4** (damage).
Your total is 14. The GM subtracts the target’s Evasion (e.g. 11). The **remainder is damage dealt**.

## 🔚 Ending Your Turn
You can **end your turn at any time**, even if you have unused actions. Doing so:
- May allow you to take a **Team Action** later
- Reserves dice for **reactions** or **interrupts**
This encourages tactical planning and collaboration.
---
## 🤝 Acting on Other Turns
You may act during **other players’ or enemies’ turns**, if:
- You have remaining dice in a relevant Aspect
- The action is a valid response (e.g., reaction, counter, assist)
These actions:
- Follow the same rules as normal actions
- Use the **current Action Load**
- Increase the **Action Load** afterward
Since your Action Load won’t reset until your next turn, acting during another creature’s turn means you’ll have fewer dice available later.
📘 **Example:**
A goblin attacks your ally. You have an Action Load of 1.
You use a Team Action (cost 1) to impose Disadvantage.
The goblin rolls its attack with disadvantage and you add 1 to your Action Load.
📝 Unlike traditional systems, you are **not limited to one reaction per round** — act as often as your remaining dice allow.
---
## 📝 Additional Notes
- If **Aspect − Action Load ≤ 0**, you **cannot choose** to act using that Aspect.
- If the **GM calls for a roll**, you always roll at least **1d4**, even with a negative Aspect.
- GM-initiated rolls may or may not consider Action Load — this is up to the GM.
- Some abilities have a **Cost of 0 or 1**, enabling small actions even late in the round.
- You may take actions using **different Aspects** in the same turn.
