On a more serious note, minions are good fodder and can soak up damage that would otherwise go directly to the demigod. If we are talking about idols, I don't believe that any general should be without monks early. The siege and melee idols are optional, but I would get them if gold is not an issue and I'm taking down towers or holding a lane. There is little more intimidating in a game than to see Erebus rounding the corner with a full set of idols and several night crawlers in tow. I would also try to max out idols for Occulus and the Oak minion build.
For QoT, skip shamblers in favor of spikes and shield, but eventually put at least one point in shamber and mulch. Idols are good for QoT and, along with bramble shield, enhance her ability to take down towers. I have yet to see a good Yeti build for Sedna, and I rarely seen Ball lightning used with Oculus.
P.S. Or was this thread intended to be a joke?
