(Druid) Stack High Levels Of Intellect Temporarily (Patreon)

The druid spell innervate was recently used by Method in their Blizzcon tournament win, here is a link to the explanation of the method they used:

Essentially the trick was simply this: a druid stacked the "lively spirit" trait which reads:

 When Innervate expires, your Intellect is increased by 77 (archvaldor note: this scales) for each spell the target cast using Innervate. Lasts 20 sec. 

The druid would cast innervate on the healer who would spam instant casts for 12 seconds using haste gear before switching, allowing the druid a huge, gamebreaking intellect buff.

Haste

I wondered if lively spirit could be exploited further, perhaps for pve. At first I thought that raising haste to insane levels could possibly raise the number of casts that could be completed in twelve seconds. I experimented using Captain Cookie in the deadmines whose food buffs stack up to 3000% haste, but this does not break the 0.75 minimum GCD on cast time, so the maximum you get from any amount of increased haste is only 15 stacks.

Multiple Innervate Stacking: Experiment

I then tried a different approach, bringing my druid and priest to the same area in Boralus. I cast innervate on the priest and immediately logged out on the priest. I then re-logged the priest 3 minutes later after innervate was off cooldown on the druid. As the old innervate expired I cast a new innervate on the priest, and the buff from the old and the new innervate stacked.

So, if we can get 10 stacks of innervate using the simple method, using the stacking method we could temporarily get 20 stacks. If we gain 150 intellect per stack, that is 20*150=3,000 * 3 (3 different traits) , 9000 intellect.

On the basis of the experiment we can conclude this method can be used to significantly raise dps.

This method seems to be capped at 20 stacks. It may be possible to bypass this cap as this happened during the experiment, but I have not been able to isolate the trigger since.
