Illuvium: Overworld - AutoDrone Runs DevBlog

We’re excited to reveal the inner workings of AutoDrone, the go-to way of obtaining Illuvials at maximum speed! Drawing on lessons from Beyond and Overworld — it’s built on dynamic mechanics that reward persistence. Two Types of AutoDrone Run are available:

Guaranteed Rare Rolls are shortcuts to the rarest Illuvials of Tier 3 and up, their properties are discussed in detail in the section on Tier and Stage chances below

Pity Counter: Rewarding Persistence

To ensure that every player feels their luck turning around eventually, we’ve implemented a Pity Counter for each Run Type. Here’s how it works:

• Tracking Progress: For every player, we track a counter increasing with each AutoDrone run that fails to yield a Holo or Dark Holo Finish. There are two separate counters—one for each Run Type.
• Reset Conditions: As soon as a Holo or Dark Holo finish is obtained for any Illuvial within the run, the corresponding Pity Counter resets. Importantly, this counter does not update mid-run; it remains fixed for the entire run and only resets after the run is complete. Thus, all outcomes benefit from a high Pity Counter
• Dynamic Odds: The finish chances adjust based on the current Pity Counter value. The formulas are as follows:
• Chance at Holo Finish: (1 + Pity Counter × 0.25) × Base Chance at Holo Finish%
• Chance at Dark Holo Finish: (1 + Pity Counter × 0.25) × Base Chance at Dark Holo Finish%
• Chance at Colour Finish: 100% minus the combined Holo and Dark Holo chances

These mechanics are designed to give you a tangible sense of progress with every run.

The base chances for each Finish are as follows:

• Colour Finish: 99.00%
• Holo Finish: 0.96%
• Dark Holo Finish: 0.04%

For example, after 10 consecutive Charged Runs without a Holo or Dark Holo Illuvial, the finish chances for the entire run become:

• Colour Finish: 96.50%
• Holo Finish: 3.36%
• Dark Holo Finish: 0.14%

Tier & Stage Chances: The Odds You Face

Our system breaks down outcomes into tiers and stages, ensuring a layered and exciting reveal process.

Tier Chances

For each Run Type, the chance to land on a particular tier varies:

Charged Run:

Hyper Run:

Stage Chances

Once the tier is determined, each outcome further rolls through distinct stages. The stage chances are split as follows:

Two exceptions to this exist:

This multi-layered approach ensures that each run is full of suspense from start to finish.

Selecting the Region

Each run doesn’t just yield a collection of Illuvials—it also decides which Illuvial Region to showcase. Can your drone find the elusive Crystal Shores? Here’s the process:

• Dominant Affinity Tracking: Each Illuvial outcome is associated with a Dominant Affinity
• Scoring Regions: For every Dominant Affinity, scores are assigned to a set of predefined Regions (e.g., Abyssal Basin, Brightland Steppes, Crimson Waste, etc.)
• Region Selection: The scores are summed across all affinities for each region, and the region with the highest total is chosen as the featured Illuvial Zone for that run.

Final Thoughts

With AutoDrone, every run offers an easily accessible glimpse into what Illuvials your drone could be getting from the world of Illuvium. From the evolving Pity Counter to the region selection processes, we hope we’ve built a system designed to keep you engaged and excited. Your continued feedback is invaluable as we fine-tune these mechanics for the ultimate player experience.

Stay tuned for more updates as we roll out this exciting new feature. Thank you for being an essential part of our journey as we push the boundaries of what’s possible in our game!
