Concept for a Greed demon, same race as Eve/Tahm.
I saw a comment about Eve and Tahm likely being based off Lust and Gluttony two of the seven deadly sins and I thought it would be really cool to get more demons along those lines. Greed ended up being by far the most interesting to me so I thought id layout a concept and see what others think.
Visuals: I was thinking he could look like a clean cut man in a suit from the start of the game, like most would think of if they were to visualize a well off politician/CEO type person. But over the game as they accumulate more and more gold they would show their demonic side more as it leaked out.
Name: Ouroboros (named after the snake that eats its own tail). Idk if its the best so would love suggestions for the name.
Passive (Accumulate): Instead of buying items/upgrading abilities via xp you solely powering up by gathering gold. Every piece of gold gives you an amount of scaling base stats and for every ~400-500 gold you can upgrade one of your abilities. (Edit: Extra part suggested. Letting him create special items when he reaches certain levels of gold so its a bit more fun to have different builds and such. I think the items should have no stats since you get that from gold but instead just have different actives/passives that you can pick and choose from. Like maybe just a set of ~12 or so items that you choose from when ever you go back to base and have say 2-3k gold accumulated. Could even just be "buying" any item from the shop for just there actives/passives without stats and you don't lose gold, can't buy 6 items straight when you get enough gold though)
Q (Enslave): Take hold of an enemy stunning them for 1.1-1.5s and dealing 80-220 (+2.5% total Gold) physical damage. You attach a chain to the enemy (tether range of ~2000) for 4s where any gold they gain you gain instead. You can reactive the skill to pull yourself to the enemy but cancel the effect.
W (Ultimate shield): Cover yourself in gold gaining a shield equal to 60-200 (+2% of total Gold) for 2s. While shielded you are slowed by 10% but are immune to CC.
E (silver tongue): In a cone in front of you charm all enemies for 1s and deal 70-210 (+2% total gold) magic damage. Charmed champions lower their defense losing all shields/buffs (likely too strong so any suggestions?) while dropping 5% of their gold on the ground which can be picked up by any player.
R (Avarice): Passive: every kill gives you 2-6 extra gold and attacking champions steals 2-6 gold from them.
Active: Unleash your demonic powers changing form and gaining extra stats (Health/AD/AS/MS/Armor/MR maybe not every stat so its not powercreep on singed) equal to X% (Depends on the stat) of total gold for 10s, extending +5s for every champion kill. While in this form you can reactive the ability again to send out a wave of liquid gold in all directions dealing 200-400(+4% total gold) magic damage to all enemies hit while leaving an area around you which grounds enemies.
The champion would be an endlessly scaling champion since gold has no cap, finding the perfect balance for the scaling would be a bit tricky so they aren't OP/Shit depending on the stage of the game. They would also likely be the most powerful champion ever as the game goes really long because they don't just gain AP/Health/Q damage like others but gain everything, I think that fits really well with the theme of endless greed though.
Im not 100% on all the abilities since it was hard to find more themes to go around the concept of greed, if you have an suggestions then feel free to say them.
