Back when Jagex started revealing drop rates of many items in-game in 2017-18, Mod Pi tweeted the drop rates from lava strykewyrms (and WildyWyrm) to be as follows:

Lava strykewyrms on-task: 1/2056

Lava strykewyrms off-task: 1/4096

WildyWyrm: 1/512

(Source: https://twitter.com/JagexPi/status/1027218577550704642)

Now, looking more into the WildyWyrm on the Wiki, it's stated that the WildyWyrm drops uniques at a rate of 8 times more commonly than the regular variants, on-task. This again is coming from Mod Pi.

So, what's going on?

  • Did he simply mean to say off-task instead of on-task when talking about the WildyWyrm?
  • Are WildyWyrm rates actually 8/2056 instead?
  • Are lava strykewyrm rates actually 1/4096 on-task? Then what would they be off-task?

My own drops more resemble the 1/4k on-task rate, but that could just be bad luck (3 rares in 12k kc). I'm not complaining as they're decent money regardless, but it would be nice to know what the actual rates are.

Hey,

Thanks for raising this, don't want my brain farts leading to invalid information!

The wildywyrm is a flat 1/512 chance (although luck rings do work) with a "1 per kill" restriction on the drop table. . I have edited the linked post to reflect this.

I also briefly checked the code for wyrm cluster tasks for the improved drop chance and it appears this is plugged in correctly for the lava noodle drops, it was fixed with a bugfix on the 6th of January.

Corrected some task-specific loot script that didn't always check against all NPCs' Slayer categories (Revenant dark beast counts as a revenant, a ghost and a dark beast for this purpose, for example)

If you believe this is still broken I am happy to poke QA to have a quick check for you.

Thank you for checking on this, so I'm assuming you meant to say 8 times more common than off-task then?

As chance would have it personally my rng did catch up somewhat and I finished the uniques at 15k last night (6 uniques total).

If I could bother you with one more question about the WildyWyrm: any chance you could tell us how the 1 per kill restriction is applied? Because it appears that everyone who attacked the wyrm has that 1/512. What I mean is that if you kill the wyrm in large groups, you'll actually see the wyrm drops far more frequently as a whole than if you were to solo it. So is this intended? And how does it pick which person to give it to?

Appreciate the time you've taken to respond and appreciate the work you do!

So unlike most bosses, rather that iterating through a list of players in the order in which they did damage (most to least) the wildy wyrm finds every every player within a 20 tile range that did damage to the wildywyrm and gives each person a roll on the drop table. This is done to bypass hte max player limit on direct damage tracking which is 16 players as the boss was designed to support massing.

If at any point a weapon piece drops then it will no longer roll for a weapon piece for subsequent players. I would expect larger groups to have a better drop rate purely because they get more rolls for a weapon per kill.
