Comepletely balanced

Went over the top with his passive. guess ill just make it back to 15-20

That's still an absurdly strong passive. Mitigating 20% of all in-hand damage is kind of ridiculous. Not to mention bland :/. Make the passive a bit more complex, either affecting Kajur's other abilities or something in general. If you want to continue with this idea, think of numbers instead of percentages or you'd have to make the percentage very small.

I wouldn't add burn damage for every single ability. It gets kind of repetitive and eh. You might be able to make it a passive tying in burn damage and his basic skills having a standard number for all burn damage? Kind of like Agni's passive but something to think about. Not to mention that you don't say how long the duration of the burns and how many ticks per x seconds.

I take it that Kajur is an assassin, maybe warrior? Fyi, having 2 stuns that long is uh.. really broken.

I suggest you work on one god concept fully before releasing many more. Also try to understand the concept of numbers and such on paper. Good luck!

Yeah I guess ill have to change him a lot. He is only my second idea
