Because those are what players want to collect. If you are looking for a Mage hat or a bear mask then you could do the whole event and not get it.
I will think all the items have the same chance to drop until proven different.
I usually do keep all my items for weeks until I am ready to turn some in. I do not get all the hats in every event.
How many Human elf pieces are there? You have a 1 in Total chance to get a piece on every drop. There has to be more than 100. So 1 in 100 chance to get a piece every drop. The game does not remember what you get, so you get repeats.
Gargoyle hard to get items are earrings and necklaces.
Why do you think the devs decided to weigh certain pieces?
Suspect it is just the luck of the draw unless it is the same on every shard. Even though the chance of every item spawning is the same in events like this there are always outliers that spawn more or less often than everything else.
Elves or humans get both human and elf pieces. Neither dominant on type.
Gargoyles only get Gargoyle pieces.
I thought the shepherd's crook is the weapon of the Lich, so it fits the Arch Lich gear.
I collected full bone set for Demonic.
In the Fey event, i looked for elven gear.
Everything looks cool in wildfire.
They should design item rarity based on event.
I don't care about rarity if I don't even know it's a rare esp when i don't need the item.
Agree with the majority here that comes down to luck of the draw and probably isn't coded to make something like a bone helm drop less.
I think it's probably a combination of what Pawain and Yoshi said with a mix of RNG in there.
I didn't really think about it until Yoshi mentioned it but something like the head slot does have many options so on top of needing to get a head piece it also has to roll being bone versus something like arms where the options are more limited.
It's also likely that most people are only keeping track of "wanted" items like bone helm / plate helm etc so they don't actually track how many quarter staffs, as an example, because they are mainly looking for something like a halberd. Do you know how many random weapons you've gotten like a cutlass or a war mace? It's likely around the same number of halberds (or maybe 1 or 2 more) if I had to guess.
Then of course RNG plays a role in all of it. Perfect example is that I think I've gotten 5-6 halberds since the event started (ballpark is maybe 1200ish drops?) but only 1 quarter staff. I've also had 3 bone helms drop for me but only 1 orc mask. Now that I think about it... I'm not sure if I've even had a war mace for me drop this event that I can remember but I'm not looking to keep those so I might have just turned it in without thinking.
Yumi, ring and bracelet are 3 most commonly drop items for me every single time
