What exactly do the Shadow Arts DO?
So, I'm making a DnD campaign based on League Lore. Atm, It's taking place in Ionia, and I have Zed as the main antagonist. That makes me curious as to how Shadow Arts actually work... Do you require the life energy of others to power them? And there seem to be different ways that Shadow Arts actually work in practice. Zed's Clones, Death Mark, Kayn going through walls, turning into shadow, etc. What exactly qualifies as Shadow Art? Is it mostly just anything that revolves around using other's life energy? Nothing has been explained specifically, unless I'm just missing something. Anybody know anything on this subject?
