T2 Arachne Profit Analysis
How much does farming T2 Arachne make per hour, and what do you gain by adding T5 Slayer?
T2 Arachne at a glance
- Average kill time: 10s (7–13s)
- Spawn time: 22s skipped / 40s unskipped
- Crystal skip rate: 15/16

Profit breakdown
Excludes the extra 10 Soul Strings per boss from placing.
- Soul Strings: 32 × 5k = 160k
- Spider Essence: not counted, because Ironman cannot sell it
- Total per boss: 160k
- Estimated profit: ~16.96m per hour (106 bosses per hour)
- At the theoretical maximum of ~116 bosses per hour: ~18.56m per hour
Same kill times and boss cycle as above. Excludes the extra 10 Soul Strings per boss from placing.
Adding T5 Slayer
Adding T5 Slayer effectively generates another ~10m per hour, assuming no RNG drops.
Using a Silk RNG meter can increase the additional profit to around 14–16m per hour.
- High RNG meter XP: once Silk is guaranteed by the meter, that kill drops Silk instead of any other RNG drop.
- Zero RNG meter XP: you need to kill 3 T5 bosses to guarantee Silk on the third kill. The first two kills can still drop RNGs normally, but the third is guaranteed Silk and cannot drop another RNG.
- The trade-off: you sacrifice other RNG-drop opportunities on the guaranteed Silk kill. With one guaranteed Silk per three T5 kills, that is roughly 1/3 (33%) fewer RNG opportunities.
TL;DR
- T2 Arachne: ~21.86m per hour
- T2 Arachne, Ironman (no Spider Essence): ~16.96m per hour
- T5 Slayer: +~10m per hour
- T5 Slayer with Silk meter: +~14–16m per hour
- At zero meter XP: expect 1 Silk per 3 T5 kills.
The profit from T5 kills with guaranteed Silk has not been tested yet.
Potential total profit
- Normal T5: ~31.86m per hour
- With Silk meter: ~35.86–37.86m per hour
Estimates exclude additional costs and assume the stated drop quantities and prices remain consistent.
