a new hero, not obtained from any existing troops.
So from what i can deduce, since troops include barbarians and valkyries we can show them to be worshippers of norse gods. And when they reach th10, the gods can grant them with a new hero. This will be thor.
Description : pleased with the advancements of the town, the norse gods have blessed you with one of their most powerful gods.
Now obviously, since he is Thor, he will cast lightning. But once he reaches, say, level 10, he will get an ability called mjolnir, where he will be granted the use of his hammer for 7 seconds. This time will increase per level. So when this ability is activated, he will be able to jump over one wall line, and will get a damage boost of 15%, increasing with every level by 1% till the first 5 levels and then by 2%. The final level will be 30.
Initial cost: 50000 de
upgrade cost: an increase of 5000 de per upgrade.
Dps: 145
Attack frequency : 3 seconds
movement speed: 24
This could be what he looks like. Only more grown up. And with the upgrade, we can make changes in his appearance. Like at level 10 give him the hammer, level 15 put electric sparks coming from his helment
