Currently the Lich has huge-ass 'Snowball' attachments on his hands that, while thematic and awesome, seem over-the-top for a freshly spawned hero. There was another suggestion
to change this, but it seems most people disagree as they are used to the Icy Hands. For good reason, as it's been there for ages and thus quite classic. Even so, embrace chance I say
As such, here's an alternative base:
(the Nerubian Tower missile, also the missile used by Skadi)
(comparison with suggestion on left, current version on right)
(movement- leaves a nice ice trail!)
And then the big Frostwyrm attachment can be used with Scepter to give Lich the badass upgrade he needs
As per normal for visuals, screenshots don't do it justice so please see it ingame using the testmap!
