T17 drop chance

Hi there...

I had terrible bad luck with t17 drops. 30 t16 maps, all voidstones in and not a single t17 dropped.

So I complained in the in-game chat and got the advice to allocate all those nodes that say "t1 - t15 maps have a X%chance to drop one tier higher". That didn't make sense to me, because, well, they explicitly say t1 - t15, so they should have no impact on the t16 to t17 conversion, but I tried it anyway... And sure enough, the next two maps I ran yielded a t17 each. What am I missing here, or was that just an incredible coincidence???

your void stones give a chance that your t16 maps drops as t17 instead, so if you upgrade your overall map drop rate your t17 map drop rate will also go up,

also using map scarabs on juiced maps, and duplicate mods on eldritch altars, and you can farm a dozen of t17 maps

With 4 voidstones your T16 map drops have a chance to become T17. With 4 voidstones you also have only T16 maps on your atlas.

Now, I might be wrong, but I think the way it works is that when, say, a t15 map tries to drop because you only have T16 maps available, it just gets poofed and doesn't drop.

Allocating those nodes let that t15 map have a chance to upgrade to T16 and then there is a chance it will become T17.

So basically those mods let you drop a lot more T16 maps which leads to more T17 maps dropping.

Note that map drops from rare conversion or from league mechanics tend to ignore your atlas, which is why you sometimes get <T16 maps

Thats half way correct.

Maps lower than T16 cant drop but will add points internally, which eventually result in a T16 drop. I think it takes 3 T15s or 9 T14s to generate enough points for 1 T16.


If you still have one or two of those "shaping" wheels on your atlas, buffing the tiers of map drops than you will drop way more T16s and the conversion rate into T17s provided by voidstones kicks in way more often as a result.

Thanks all... :)

The t1-t15 upgrade nodes = more t17 maps due to the map equity system.

This isalso why singular focus passivehassuch a negative impact on your t17 drop chances.
