Dude, EoM is like a 2 second 0 cost ability. You cast it, you have the animation delay and that brief pause before you can take another action. You can only cast 1 ability in that time period. I suppose some things you could get 2 off, but doubtful, unless they're instantaneous cast.
It's 3 seconds. Warp Strike is Instant, Spine attack is .3 seconds and Warp Area is Instant. Shadow Swap is 1 second
The issues are:
- using EoM breaks your current action (like Wand of Speed), sometimes leading to them escaping as they leave your cast area:-(
- the enforced latency of Demigod make it tough. There is an inherent .350 second delay to all your commands.
Push EoM
.350 seconds later, start your Spine Attack : .350
.3 second cast time : .650
.350 seconds later, start your Warp Strike : 1.000
.350 seconds later, start Warp Area : 1.350
Finish Warp Area(1.6), take Mana Costs : 2.950
Which is less than 3. The issue, of course, is that you have very, very little room for human error. That said, replacing the Warp Area (which sucks anyway 
) to a Shadow Swap gives you a net gain of .6 seconds of human-error-time, giving you roughly 2/3rds of a second to screw around with.
It isn't hard to get 2 abilities off, given that they are well within casting range. Getting all 3 off is very difficult, though duable.
In theory, you could get all 4 off, since you don't pay the mana costs for Warp Area until AFTER it finishes, but it makes an 'mana check' while EoM is still active.
.350 seconds later, start your Spine Attack : .350
.3 second cast time : .650
.350 seconds later, start your Warp Strike : 1.000
.350 seconds later, start Shadow Swap : 1.350
1 second cast time : 2.350
.350 seconds later, start Warp Area : 2.700
Pay mana costs for Warp Area : 4.300
So, you'll pay for the mana-costs still, but what if you only have 200 mana? Well then you only paid 200 mana to cast, not the full 500 or however much it is. It's a net-gain.
