Hello. Some interesting comments here on the dice system.
If anyone is interested, I'm about to design some custom D6 for HQ. They will be 19mm x 19mm x 19mm and plastic, with an inset for stickers to be inserted.
I aim to create:
x2 - light random wandering monster dice (yellow with specific creature in dark green)
x2 - heavy random wandering monster dice (dark green with specific creature in yellow).
x2 - random treasure dice (orange with black silhouette of item found)
x2 random trap dice (purple with trap marked in white)
x2 random weapon found (blue with weapon in tan)
x6 - standard black shield, white shield, skull skull dice (black on white & beefed up a little in appearance)
x2- stronger enemy dice with two black shields, two white shields, two skulls (white print on blood red)
x2- powerful evil dice with three black shields, one white shield, one poison attack, one critical blow (black print on gold)
(+ 120 dice stickers + a few spares in case magic happens)
( I need 2 of most because of the complexity of tile choices I have)
I have the ability to offer dice in the following colours: purple, yellow, red, green, orange, blue, black, white
But can also custom design the stickers that go onto them

That kit above, I can do for $20 USD + postage. And I'll custom design dice with your preference of coloured dice, sticker and/or your images for an extra $30 USD.
I'll post some dice images when I'm closer to making them available from my site.
