The update notes have this cryptic line
• Some item drop rates have been adjusted.
There have been many rumors and speculation as to what that means in terms of nodestone, arcane symbol, and droplet farming.
Nexon Korea claims that the base drop rate for these things has been raised, but the effect of drop rate lines on equipment has been reduced. Some KMS players claim that even people without drop buffs have noticed a decrease in their collection rate.
The new drop rate buff formula has not been released, and people speculate that it's "like IED" in that it has heavily diminishing returns and an asymptote at 100%.
But as far as I know there is no proof, and even if there were, GMS is not required to do things exactly as KMS did.
So, I'm trying to find out some facts, assuming that Tespia rates are the same as the eventual live server rates we'll get.
For my first test, I killed 10k wolfruits with no drop gear, familiar, skill, or coupon of any kind.
On Kradia I got 1 nodestone. On Tepsia I got 7.
I did not find any arcane symbols in either server.
I'm aware that the sample size is apparently too small for an accurate assessment, but on the face of it it seems that the base nodestone drop rate did get significantly buffed.
I will continue to test this, and update this post. If anyone else feels like grinding as well, please do so and post your results below.
Edit:
10k wolfruits with Big Spider, on Kradia: 2 nodestones, 2 arcane symbols. On Tespia: 6 nodestones, 2 arcane symbols.
The Kradian results are as might be expected, but the Tespian are odd. Sample size is obviously much too small. But on the face of it, it seems the Big Spider familiar did nothing.
