Lumin Vase Lumin Ring

[Kymedorf]

I applied Lumin Ring to the Lumin Vase and while the card states it will apply two Lumin (so double effects x2?), only one actually works. I didn't get neither triple nor quadruple effects depending on interaction as I expected before I did that, it just ate the charm and changed the interface.

The lumin status is a bit atypical to begin with (e.g., its expiration condition is a card receiving lumin), but in this context it works a lot like demonize. 2 stacks of demonize isn’t quadruple damage, it’s double damage twice. I don’t know entirely how it gets handled internally but I imagine it’s one of two cases:
1. First stack of lumin is applied, and then the second stack is applied, but since only one lumin stack is allowed to exist, the first stack immediately ceases to exist.
2. Like demonize, two stacks of lumin is just double effects two times, but unlike demonize there’s nothing to make the lumin count down, so there’s no inherent benefit.
Regardless, this seems intentional, so I’d recommend applying the lumin ring to the target rather than the vase so you can get a +2 out of the charm over a +1.

Ah yes, I had this happen too! Meant to sent a bug report about it - thanks for the reminder.

@Redlegoguy1 - I agree and think the 2nd option is likely what's going on. Main thing my side on this though is, from what I can tell, the game is normally great at showing you what cards you cannot apply charms to. If the Lumin ring would be completely redundant on the vase, it ideally shouldn't be an eligible target, personally.
