During beta, it was revealed that the Tier 17 2PC bonus would be "2 charge Inferno Blast". At the time, most of the Ignite/Combustion silliness was focused on Ignite compression, which meant that people think too much about it. I've always thought of this as a very abusable mechanic though, such as creating multiple waves of Living Bomb explosions. The trick I have for you here uses 2T17 together with Prismatic Crystal for boosting Ignite. Here is what you do:
1. Pyro camp on boss until you have both "Pyroblast!" and "Heating Up".
2. Summon Prismatic Crystal.
3. Time Warp, trinkets, potions, everything.
4. Build a big ignite on Prismatic Crystal: Fireball+Pyroblast 2 or 3 times, and then dump all Pyroblasts. Make sure to leave time for 2 GCDs on Prismatic Crystal.
5. Quickly use Inferno Blast twice on Prismatic Crystal.
6. Switch to boss and use Combustion.
*NEW* Here's a video of how it looks in practice. http://youtu.be/Qw415ks-aVY" target="_blank
When you use Inferno Blast on a target, it "copies" the Ignite over to all neighbouring targets. Targets that already have an Ignite will add this spreaded Ignite to the existing one. By spreading twice, the large Ignite you've built on the Crystal will be copied twice to the boss, inflating the value of the ignite by a significant amount (<=83.33% in theory). Here is a log of what it looks like, with a shadow priest, self buffs and consumables: https://www.warcraftlogs.com/reports/KR ... e&source=1" target="_blank
Komma attacks prismatic Crystal to generate an Ignite of ~14K ticks, quickly spreading it twice:

There are some requirements for this trick to work. The first is that you must have enough haste to get close to 1 second GCD. Time Warp, haste buffs and maybe even haste trinkets are desired. The second is that you need a substantial amount of crit to even chain "Fireball+Pyro" into Prismatic Crystal, so a crit trinket proc (such as Sandman's Pouch or Goren Soul Repository) is most likely required.
Taking a step back though, this "double spread" strategy might not be optimal. Maybe a simple "chain a few Pyros into PC, Combust and spread" strategy is better, because you can gain double Combustion ticks while PC is still up. It is too early to say now, and a lot of work needs to be done before SimC can model our current Prismatic Crystal Combustion tricks.
What are your thoughts on this trick? Do you guys think this can be a thing?
