By this point, Draco's concoction was about to enter full swing. He had already begun methodically placing the various reagents into the cauldron, and they naturally reacted when put under fire.
The cauldron began to shake a little, which was a normal response to such a heavy brew. After all, Draco usually relied on Worldly Energy to suppress the violent reactions of the different materials placed within while strengthening them and assisting them in fusing.
Without it, he was as vulnerable as any other Master Rank Alchemist when making Epic stuff. This was one of the reasons that despite there being no limit on the amount of those with a Master Rank Tradeskill in any given Tradeskill, there were very few Epic items about.
The average Master Rank crafter had only a default 10% success rate and whatever technique they used also added on a bit of fluff. If they had titles or other methods, that was fine too.
