Dice drops - levels, numbers & modifiers

[Gammoregan]

I'm currently on level 150 and have spent around the past 50 levels trying to find the right die for my deck but have had no dice. Does anyone know what the loot tables look like and how they vary throughout the levels? I'm currently looking for "The Holy," an attack die that's all 6's that I've found on a previous run. As well as a defense die without modifiers, or with the glass modifier. None of these have shown up in all this time.

My reasoning for this search, for the curious, is I'm trying to build a specific optimal deck. "The Holy" will be my second attack die, my other is a glass one with all 6's. I want to put Grow on The Holy for the variety and to see if it helps at higher levels when enemies don't all die on the first turn. I already have a defense die with grow but wouldn't mind a second one, or a glass one. The reason I don't want any modifiers on the one I pick up is it seems to me that having bonuses on dies when they're first picked up reduces the numbers on their faces even when fully buffed - i.e., ending up with a gold die that has a highest face of 5 and won't allow further gold upgrades.

I just found "The Holy" as a reward on floor 209. I did stop looking for around 25 floors after my previous post and then started looking again, settling for some lesser dice which I will now throw out. Still hoping for a better defense die though, all I found was a "gold" which has 5 faces that are 3 and 1 face that is 4. All because it's hollow, though I've seen flash dice with the exact same stats.
