Is Guild Shop the only place to find him?
How much does he cost?
How does his 30% damage skill work on Guild War Boss?

You get roughly 1100 points. Sometimes more, sometimes less. Unsure why.
I would personally buy 5 Zeus. 4 to create a 8*, and 1 6* left over in case you need to skimp on CP randomly.
Context: Let's say I'm primarily running a White Mono team, but with a Zeus. That means my leader is either giving x2 Atk/HP or x2.5 HP to all white creatures. Zeus is clearly there just for the 30% activate. As a result of this fielding the 8* for 30CP is not as valuable as saving my CP for the White side of the team. So in this example I would only use the 6* Zeus.
That is of course me being fussy and trying to min/max my team layouts, which not everyone is into.
