💠Introduction

What’s up, folks? Welcome to my beginner series where I’ll be taking a closer look at specific events that may be difficult for early-stage players or new events. In this article, I’m going to explore Rune Factory’s revamp, what it entails, and the updated odds and cost.

💠Overview

Rune Factory is the new weekly event replacing Sparks of Galaxy, running for three days each cycle from Sunday through Tuesday. It introduces a consumable entry token, Energy Core, and a new shop currency, Rune Insignia, which you earn and spend in the event store. You can convert existing Frosty Orbs at a rate of three orbs to one Energy Core to stock up on entries.

💠Rules

During the event, using Energy Cores in the Rune Factory grants random item rewards while also filling an Energy meter. Once the energy value reaches 100%, the next Energy Core used is guaranteed to produce 70 Rune Insignia, after which the Energy meter resets. It takes 101 Energy Cores to guarantee 70 insignias. Patch 2.9.2 also introduced more Rune Insignias in each draw. Instead of two out of four slots of gold, one slot was replaced with two Rune Insignias and the other was replaced with four Rune Insignias. Hitting any of the three insignia slots will reset the energy value. Rune Insignias can then be exchanged in the Factory Shop for rare rewards. It’s extremely similar to Sparks of Galaxy in that sense. However, as the meter fills up, your chances of hitting the insignia does not increase. Additionally, players can purchase three Energy Cores for 1,000 Gems, up to 20 times per day of the event.

💠Rewards

Each draw has a 0.5% chance to award 70 Rune Insignias, a 12% chance to get four Rune Insignias, a 24% chance to get two Rune Insignias, and a lowered 63.5% chance to get 10,000 gold. Rune Insignias can be exchanged in the Rune Shop for rewards, including 280 Inferno Insignias for 70 Rune Insignias, five Dragon Essence for 40 Rune Insignias, or 100 Holy/Shadow Dragon Crystals for 20 Rune Insignias. Additionally, three Frosty Orbs can be traded for one Energy Core, allowing continued participation in the event. The rewards haven’t changed since the event was released.

💠Math

When Rune Factory was first released, the average number of rolls to get around 70 Rune Insignias was about 81 pulls, which cost about $20 if you buy the cheapest packs. Based on the drop rates, each roll yields an average of 1.31 Rune Insignias (0.5(0.5% × 70) + (12% × 4) + (24% × 2)(0.5, so reaching a total of 70 Insignias takes approximately 53–54 rolls on average (70 ÷ 1.31). The pity system at roll 101 is effectively irrelevant in practice, since the probability of going 100 consecutive rolls without receiving any insignias is astronomically small, and any insignia drop (2, 4, or 70) resets the pity counter well before it would ever trigger. It costs about $7-$8 cheaper.

💠Summary

Patch 2.9.2 introduced a small Rune Factory revamp, adding daily free Energy Cores, reintroducing Gem packs for purchase, and slightly reducing the cost of rolling for the jackpot, making the event more accessible and less resource-intensive for players.
