oh wow. this is beyond my expectation lol. thank you so much for the interest! renders are coming also, in the meanwhile all can i do is answer your question lol.
so...
Yes please. I'm seeing a lack of upside-down crosses. Maybe that could be a novelty / shift icon mod?
Maybe a set of teeth or horns for novelties?
More ideas for novelties:
-demonic looking sword/ceremonial knife
-drop of blood
-pentagram
-skull w/crossbones
thanks for the novelties input! will come soon tho, drops of blood looks nice, ceremonial knife will be too "witch doctor" for this set.
that skull also will do, but i'd have to change it to diablo skuul or demon skull, maybe something like this.

as for the upside down cross.. i didn't remember that diablo had upside down cross.
Take all of my moneyyyyy
Suggested novelties:
* Town portal
* Potions
* Gemstones?
i can also do this. but i need to think about which theme do i want to use, from Diablo 2 or 3.
but gemstone... which one? legendary one or usual one? (emerald, ruby, topaz etc)
Sweet. The red used in your image looks rather desaturated in comparison to DCS Sanctuary, though. Can we get some idea of the actual colours the set will end up with?
Also, a mono-legend version of the alternate numrow, with just the Roman numerals, would be neat. And moar novelties.
yeah, we're changing the red a little bit as we want the set to match the whole diablo universe, and we think our red are more representing the whole universe.
as for the actual colour, the renders with proper lighting will come up. so please wait.

thanks for the input!
i'm trying to accomodate all the inputs, as we know that we can't add many keys if we want to stay on our plan to keep this set's price below 99.
