As for now IF is not free. While the tooltip doesn't mention any manacost it actually burns about 2k mana. The weird thing is that IW does not use any mana at all so it seems like they forgot to actually remove the mana cost of IF. In any case until they fix this bug or add a mana cost to IW too the "inner dancing" must be used with caution as even those 2k mana can make the difference between life and death.

According to posts on arenajunkies, IF starts costing mana if you spec into Inner Sanctum. Unable to verify this from work.

Just checked that out with my secondary spec that has Inner Sanctum 3/3 and yeah IF is costing about 2900 mana to cast unless you are below 2900 mana then it consumes no mana and goes off as normal. Interesting bug.

This is correct. However, it is a little misleading because it does not add in the base regen for a level 85 character. This should be the regen formula for Disc only.

Out Of Combat Regen*
Spirit regen = (Sqrt(int) * spirit * .016725) + 1029

Combat Regen*
Spirit regen = ((Sqrt(int) * spirit * .016725) * .5) + 1029

*taken from theory crafting spreadsheet.

I've just done a quick bit of math on 1/2 Strength of Soul and at 100k mana (a little low in raids, I know, but not far off in entry level gear) we see the value as:

0/2 = 6k/15s = 400mana per second
1/2 = 6k/13s = 460mana per second

Therefor assuming Heal was worth casting and not wasted mana, 1/2 strength of soul would be worth 60mana per second, with more at higher mana pools.

This doesn't count the fact that you're casting PW:S more frequently, which is relatively inefficient as healing goes. The small efficiency hit is harder to quantify since it changes with mastery, spell power and other talents. but generally, the above numbers should give you a rough idea of the value of SoS 1/2.

depends on your maximum health. DA (and possibly PW:S?) won't go above 20% of the casting player's max health. Just tested mine self buffed and it caps at 23125, which is 20%, so yeah. Check your greater heal crits and see if you're hitting the DA cap with it.

to help you test it:
0.3*1+(mastery/100) = DA%, multiply that by your greater heal crit amount and see if it goes over your cap.


In response to the post below, rather than spamming the thread.

I've just tested this and yes, it is giving int rather than SP. This may give it an edge for raiding disc priests. the wowhead link for the spell is Lightweave - Spell - World of Warcraft, some quick research is showing this to be a tooltip error.

580int for disc is adjusted to 700 through enlightenment and blessing of kings, which translates to 10500 additional max mana for 15 seconds. 1.5% of that is returned directly through replenishment active at the time (157 mana), a further 6% (630mana) of that will be returned from a single rapture proc (you could in theory time it to get 2, but the focus that would require is rarely available in raids). While int is heightened, base spirit regen is also up. combine all this, and we find that a single lightweave proc is worth roughly the same mana as a single dakrglow proc for disc priests (not counting additional benefits from combining this proc with a shadowfiend, of course). The proc chance is 20%, 60sec internal cooldown, versus darkglow's 35%, 60s ICD. So whilst darkglow will come up more frequently and thus can be worth slightly more mana over the course of a fight, lightweave gives a competitive mana regen whilst also giving some extra crit and spell power whilst it's up. If you do happen to have this proc with devine hymn or shadowfiend up, the mana benefit of it goes far beyond darkglow.

Lightweave embroidery has a wrong tooltip. It procs 580 Intellect rather than the 580 spellpower as it suggests. Which of course is a huge difference.

It does actually consume ~2000 mana for me as well, but if you have less mana than it consumes available it doesn't consume any mana but still casts. Inner will doesn't consume any mana though.

I noticed this the second day of cata (I think i was 83 at the time) and put a post on the wow bug report forum but got no response. A couple days ago it stopped consuming mana, but the next day it was back to consuming mana again.

Ahh, thanks. Makes sense since I just respecced back out of inner sanctum to a atonement build for heroic healing. I'm surprised how effective it is even in heroics, just spam smite (pulling about 3k dps) and throw in 30% cheaper penances and a PWS every 15s. If I get behind on healing on the tank, pop archangel and throw some GHeals. If the whole group takes AoE, pop archangel and throw some PoH. I didn't bother with smite glyph as I'd have a huge chance of missing holy fire anyways on bosses, if the divine accuracy glyph included holy fire for the hit bonus I would probably consider it.

Took a little bit getting used to but I find is much better than both SoS/Heal and ToT/GHeal. SoS/Heal just doesn't have the throughput needed for heroics, ToT/GHeal costs much more to maintain. Plus I add 2-3k dps to the fight, so that's always good. Only problem is smite being 30 yard range and the heal only being 15 yard range from the center of the target which makes the spec suck quite a bit for AoE damage fights with a 3xranged group.

That's the way to do it. Don't forget your PI is just sitting there if you don't use it. It's much more valuable these days for self use than it is on a dps since they don't generally care about the 20% mana reduction whereas you obviously do. Pop that on yourself with AA up and go to town. You will have your group topped up after a nasty near wipe or CC broke OOPS moment and still be ready to hit the next pull without stopping to drink half the time.

Also the range on the atonement heal is 8yds not 15. But it's still quite useful on many encounters. If you're straight up disco like myself then it won't be a big issue for you to run a secondary spec that leaves out atonement/AA.
I'm running this for my secondary. (31/8/2)
The Psychic Scream Glyph I actually have for Nefarian, but it's VERY useful in 5 mans to take some heat off the tank or yourself. Also if you renew a lot in 5 mans to avoid taking grace off the tank then renew glyph can be subbed for Barrier. Also if mana is more of an issue I would swap 2/3 darkness for 2/2 Veiled Shadows. I'm not sure what kind of gear you're working with since your profile link is a lvl 80 shaman :-p

As far as the smite glyph. Smart choice in not taking that. Aside from the hit factor, it's just not that great of an idea to cast it at all. The dot only lasts for 7s and at about 1.7-1.9s smite cast time (depending on your haste) you could get 4 smites, if under 1.76 cast time, (3 if cast time is over 1.75s) in during the time of the dot and the 5th(4th) one would go off after the DoT expires. Or you could just cast 6 smites and do more healing/damage.

Assuming you meant the holy fire glyph, there.

Whether or not holy fire is worth it in atonement situations depends on how you want to balance damage versus healing. Holy fire is 3/4 the cast time of smite for close to the same damage, but since a lower % of your damage overall is coming from smite you will get less healing done on atonement. It really is a matter of using what the situation demands.

To clarify this and answer my own question, this has been fixed/patched. Multiple shields consumed at the same time return mana for only one shield.
