If you thought farming 16 Skullsworns would be a breeze, think again. Based on updated community data, the drop rate for Skullsworn in Spirit Keep (Brutal difficulty) continues to hover around 1.8%. That’s right – just 1 Skullsworn every 50–60 runs, on average.

Even after thousands of player-submitted runs, there’s no magical bump in drop chance. In fact, most veteran players still advise sticking to Brutal Stage 3, as higher stages don’t offer noticeably better rates in the raid Skullsworn grind – they just burn more energy.
The Math Still Hurts
If that 1.8% drop rate holds true, you’ll need roughly 889 runs to collect 16 Skullsworns. At 8 energy per run, that’s 7,112 energy total. With a typical “free-to-play” energy income of around 740 per day, it’ll take you just over 9–10 days of consistent farming – assuming perfect luck (which we all know isn’t happening).
RNG and Reality
Don’t be surprised if you go on long cold streaks or get three Skullsworns in one sitting. That’s just RNG doing its thing. The rate hasn’t changed since 2020, but patience and planning still win. If you’re tackling the raid Skullsworn collection challenge, be ready for a serious test of your endurance.
Quick Summary
- Drop Rate (Brutal): ~1.8%
- Attempts Needed for 16 Skullsworns: ~889

If you’re aiming for Skull Lord Var-Gall in 2025, start grinding early – Skullsworns won’t farm themselves.
