I tend to use Gnome Weekends to force myself to do some Explore instead of PvP, to farm the traitstones that I may be after, so I will usually focus on specific Kingdoms: however, a couple of guildmates who go kingdom-hopping have reported (with screenshots) a much higher Gnome appearance rate (and vault key drop rate @ ~30-40 for ~1000-1500 battles), so I wondered: are there any factors that influence when a Gnome will appear in an Explore battle?
Also: do we have any data on how often will a Vault Key will drop from a Treasure Gnome? Gnomes seem more likely to appear in Explore than in PvP: what is the ratio?
Just trying my luck in case any of the GoW Mathemagicians have run some numbers on these, or if the % are available somewhere, just like how the Chest Drop Rates are now public.
It’s all rng. As for droprate my personal data showed on average a gnome would appear 1:11 and would drop a VK at about the same ratio 1:11. So approx a VK every 125 battles.
If you don’t need traitstones better off doing easy challenges for more battles per hour.
