Got question about Liches rank!

[jinxeverything]

Hi there, yesterday I got my very first Kuva Lich and a question came to my mind, what the difference between rank 1 and rank 5 aside from planet influence, what do I gain if I let it achieve rank 5?

Anyone with experience can answer this for me?

Thanks.

HIgher Rank Liches are kind of the same as rank 1. 

The difference is that the enemy level in kuva lich controlled mission increase also the level of the lich increases too.

you get more kuva from higher rank liches if you fail to kill them.

Nothing really, they just become harder to kill and deal more damage. There's an achievement for finishing off a rank 5 lich though.

You get more Kuva from a Rank 4.

ALSO they increase their planets to play Lich missions on

Not what I expected (was hoping for more boost to weapons stats) but thanks for answering my question guys.
