Exploring
spirit as disc
With no rapture
First let us consider the relationship
between mp5 and spirit from gear.
Mp5
|
Spirit
|
Intellect
|
| 13162 | 12690 | 14540 |
| 12534 | 11578 | 14540 |
| 12534 | 11578 | 13325 |
| 12242 | 11061 | 12401 |
Simply from looking at the table, we
see that intellect has no impact on mp5.
Assuming that mp5 is proportional to
spirit, we can say (where c=some constant of proportionality)
change in mp5 = c * change in spirit
Plugging the values in c = 0.565
And base:
| MP5 | Spirit |
| 6125 | 222 |
We can conclude that
Total mp5 = base mp5 + (0.565*spirit)
And using these values :
6125 = base mp5 + (0.565 * 222)
base mp5 = 6000
Total mp5 = 6000 + (0.565*spirit)
|
Rapture
Rapture returns 200% spirit, with a 12s
cooldown.
PW:Shield costs 18300 mana.
On proc, rapture returns 2*spirit mana
- 18300
Mana per minute = n * (2*spirit –
18300)
Mp5 = (n/12)(2*spirit - 18300)
Utilizing rapture n times a minute
(where n ϵ [0,5] ) gives
an equivalent mp5 of:
mp5 = (n/12)(2*spirit -18300)
Mp5 from rapture = (n/6)(spirit – 9150)
|
Combining Rapture and Passive Regen
Total mp5 = 6000
+ (0.565*spirit) + (n/6)(spirit-9150)
Total mp5 = (0.565 + n/6)spirit + 6000-1525n
|
Spirit from gear as a human.
Total mp5 = 6000
+ (0.565*1.03*spirit from gear) + (n/6)(1.03*spirit from gear –
9150)
Extra mp5 for
human racial = (0.565 * 0.03*spirit from gear) + (n/6)(0.03* spirit
from gear)
Extra mp5 for human
racial = (0.005)*(3.39+n)*spirit from gear
|
Extra mp5 from being gnome.
| Mp5 | Spirit |
| 13363 | 12500 |
Mp5 = base +
0.565*spirit
base = 6300
As this
correlates with the gnome racial *1.05, we conclude that the base mp5
is related to the mana pool size.
Base mp5 = 0.02
* base mana pool
and for a gnome
the base mana pool is 1.05 times bigger, and gnomes get an
additional:
Extra mp5 for gnome racial = 0.05*300000*0.02 =300
|
Combining the two, we have:
Thus we have:
| mp5 = 6000*mana pool modification +(0.565*spirit modification*spirit from gear) + (n/6)(spirit from gear*spirit modifier – 9150) |
| Human | Mana pool mod = 1 | Spirit mod = 1.03 |
| Gnome | Mana pool mod = 1.05 | Spirit mod = 1.00 |
| Meta gem | Mana pool mod = 1.02 | Spirit mod = 1.00 |
Now let us consider mindbender:
Mindbender
returns 1.46% mana per attack, and attacks 10 times before despawning.
This gives us a
total of 14.6% max mana.
(nb: this does assume you can cast mindbender on cd, ie that the boss doesn't go immune).
mps = 0.146 * 300000*mana mod * (1/6)
mp5 = 3650* mana mod
|
Finally, a complete equation for
the mp5 as disc:
| mp5 = 9650*mana pool modification +(0.565*spirit modification*spirit from gear) + (n/6)(spirit from gear*spirit modifier – 9150) |
| Human | Mana pool mod = 1 | Spirit mod = 1.03 |
| Gnome | Mana pool mod = 1.05 | Spirit mod = 1.00 |
| Meta gem | Mana pool mod = 1.02 | Spirit mod = 1.00 |
Using this, we
can discuss the two main meta gems healing has to offer:
| Revitalizing Primal Diamond | +432 Spirit |
| Ember Primal Diamond | 216 Intellect and 2% max mana |
I'm a human, which meta should I
use?
Mp5 Revitalizing = 9650
+(0.565*1.03*(spirit from gear+432)) + (n/6)((spirit
from gear+432)*1.03 –
9150)
|
| Mp5 Ember = 9650*1.02 +(0.565*1.03*spirit from gear) + (n/6)(spirit from gear*1.03 – 9150) |
And the
difference between the two can be given by taking ember away from
revitalizing:
| Mp5 (revitalizing – ember) = -9650*0.02 + (0.565*1.03*432) +
(n/6)(432*1.03)
= 251.4024 – 193 + (74.16n)
= 58.4 + 74.16n
|
And thus we see
that the revitalizing pulls ahead even with no rapture a minute - the more rapture you do,
I'm a gnome, which meta should I
use?:
Mp5 revitalising = 9650*1.05
+(0.565*(spirit from gear+432)) + (n/6)((spirit
from gear+432)–
9150)
|
| Mp5 Ember = 9650*1.05*1.02 +(0.565*spirit from gear) + (n/6)(spirit from gear– 9150) |
The difference
between the two:
Mp5 (revitalizing – ember) = -9650*0.02
+0.565*432 +(n/6)(432)
= 51.08 + 72n
|
Showing that for
a gnome the revitalizing still leads, although in this case with less
margin and less contribution from rapture.
Comparing gnome and human racials
(or, I just made a priest, should I be human or gnome?)
Mp5 as a human =
9650 +(0.565*1.03*spirit from gear) + (n/6)(spirit
from gear*1.03 – 9150)
Mp5 as a gnome =
9650*1.05 +(0.565*spirit from gear) + (n/6)(spirit
from gear– 9150)
mp5 (human –
gnome) = -0.05*9250 + (0.565*spirit from gear * 0.03) + 0.005n*spirit
from gear
| Mp5 = 0.005n*spirit from gear + 0.01695 * spirit from gear –
0.05*9650 = (0.005n + 0.01695) * spirit from gear – 0.05 * 9650 |
To make the two
equivalent, we see:
0.03195*spirit from gear = 0.05*9650
spirit from gear = 15101.7
(3 rapture a minute) |
(0.005n + 0.01695)spirit from gear = 482.5
spirit from gear = 482.5/(0.005n + 0.01695)
(n rapture a minute) |
So you would
need 15.2k spirit from gear & flasks to make being human give
more mp5 than being gnome as a disc priest, assuming they use rapture
3 times a minute.
The more we
rapture, the less spirit we need from gear : 11501.79 spirit from gear
is needed to make human better than gnome at 5 rapture a minute
(literally rapture on cd).
Of course, this
does not take into account the human racial “trinket”, which is
incredibly useful in pve boss encounters. I list a few:
- get out of “amber prisons” on Windlord
- remove fear in Grand Empress
- Remove pinning arrow on Spirit Kings
