I like to have the bonus on my holgar and drin with Yggdrasil. At least it should be able to turn off
True Kami, especially after the update it only makes sense that your main carry has the Roordahuizum so Ygg will be doing all the drinking. Since Ygg's function is to share potion effects maybe create a drinking effect on Ygg instead?
Maybe we can add a new black market item with this ability, so it can be used independent of Roordahuizum?
It could have an extra ability: whenever this card drops another card of equal rarity drops. This way it wouldn't be a disadvantage to own that card.
Actually, that's what all cosmetics have by now (thinking about it, I should list it there too).
I did mention a toggle ability. So if you use Roordahuizum on a non-drinking tower, then you'd just not use the ability.
