Sorry if this has been looked into before I have done some searching for the past few weeks ever since I first got Moonwell Chalice without being able to find any information on it.
Looking just at the staghelm fight as there is no movement in the beginning of the fight. Last week using normal VPLC + H mirror. This week using moonwell chalice + H mirror.
Last week my maximum crit was 135158 this was with the revelation buff, arcane power, imp mana gem, volcanic potion all up. Mana gem was used during volc pot + power torrent buffs.
Giving me approximately 4078 mastery +/- 50 or so given recent gear changes along with approximately 15200 spell power +/- 150 or so given recent gear changes.
Compared to this week my maximum crit was 158520. However this was with revelation, blessing of the moonwell, arcane power, imp mana gem, volcanic potion and incanter's absorption (from flame scythe). Mana gem was also used during power torrent + volc pot.
Giving me 5778 mastery with approximately 17500 spell power +/- 100 or so.
Last weeks crit was 17 seconds into the fight with 1 clearcasting proc, this weeks being 20 seconds into the fight also with 1 clearcasting proc. Meaning mana percentage would have been extremely close to one another, slightly higher mana percent with the small crit.
One would assume having an extra ~2300(more than 10% increase) in spell power with an extra 1700 mastery(~14% increased damage) along with all the other damage/crit multipliers. I should have achieved much higher than just a 23k increase to the crit.
The WoL can be found here:
Last weeks smaller crit
This weeks larger crit
Ever since I got the moonwell chalice a few weeks ago attempting to double stack mastery procs it has felt as if my hits and crits weren't significantly larger than just having one mastery proc up.
Any information from someone better at the math or someone that has also looked into this possible mastery 'cap' would be greatly appreciated.
