interesting thing happened tonight, probably a coincidence but I don't put anything past hidden Korean RNG systems.
So i'm grinding away leveling my valk, hit 45, decide that, while it's less efficient exp, that i'm going to grind treants to 50 instead of catfish so I can farm tree belt, 2 birds, 1 stone sort of thing.
I've killed enough treants on my other characters to have pretty much all the knowledges unlocked, doing guild quests and just grinding, except for Twin Headed Treant.
So i'm grinding away for about an hour and nothing. I didn't get any black stones, only got 2 trade item drops, and never unlocked twin headed. I had unlocked the node before I started, but decided to drop all my energy in and leveled the node up to 2.
another 2 hours, fucking nothing. I get 1 blackstone (weapon). no more trade drops. over 1k of each of the 4 separate little bounty item turn in for X silver dealios, but jack shit otherwise. At the very last minute twin headed lore finally unlocks.
I was in Mediah E1 just because it's my normal channel, it's the first channel on the list that isn't crowded when I log in during JPN time. Now by this time it's early morning east coast time, guildies are starting to get online before work to check shit. Guild master needed me to switch to Velia E1 for contract renewal so I head to trent safe zone, swap, and handle that.
I run out and the first treant I kill drops Tree belt. It was an old treant, so it wasn't even the lore unlock from twin headed that added the extra luck for RNG.
Just a coincidence? are some channels unluckier than others? Is there anti-farm code, spend too long killing x in a certain area and luck decreases, but can be reset by channel swapping? Does investing in nodes actually reduce your chance of drops rather than increase (as i've heard that rumor)?
