With some very quick tests;

25% Proc chance
20 Second Internal Cooldown

Commentaire de skribs

From a healer perspective:
I'm assuming an average cast of 2 sec, as most heals seem to be 1.5 sec or 2.5 sec. Simple math puts 1/proc chance * 2 + ICD as time-to-proc.

Power Torrent:
45 sec ICD, 33% proc chance. Roughly 51 seconds between procs, lasts 12 seconds, means ~24% uptime, or 120 intellect. Factor in that you do not get the benefit of using 7500 extra mana during the procs, and this is weaker than that.

Heartsong:
20 sec ICD, 25% proc chance. Roughly 28 sec between procs, lasts 15 seconds, means ~54% uptime, or 108 spirit. Unlike Power Torrent, you get the full benefit of the spirit gained during combat.

Hurricane:
45 sec ICD, ~12.5% proc chance. Roughly 61 sec between procs, lasts 12 seconds, means ~20% uptime, or 90 haste.

Personally, I'd recommend Heartsong for healers. I'd prefer to have spikey regen than spikey healing (since regen is going to even out over a period of time, while your healing is going to only matter until the target is at full health). Haste procs also tend to screw with my precasting, and Power Torrent just doesn't appeal to me as Int on gear provides benefits that int bonuses mid-combat do not.

It seems this procs not only off of casts but also ticks of periodic spells as well. I don't know if this is true in all cases, but my renew ticks are giving me the buff.

Can anyone confirm / deny if it stacks with procs from Blood of Isiset / Tear of Blood?

Commentaire de duskmay

For some reason, the healing from Bandage ticks also procs this.

While some people might not care, I think it's a shame this doesn't have a really fancy graphic like all the other new Cataclysm enchants...

I haven't been able to get Heartsong to proc off of Power Word : Shield on my Disc Priest and I can't seem to find any info confirming or denying the possibility. Has anyone seen Power Word : Shield proc the enchant? You would think that if healing from a bandage works, the healing from a glyphed spell should, too, but I've been trying to test with no luck.

I agree with you entirely on the way you calculated uptime of procs. It can be nuanced as with knowing if a multi-cast spell can have multiple chance of proccing the enchants or if HoTs proc them. However, I feel it is incomplete. Intellect cannot be considered a purely throughput stat, since lots of buffs procure mana based regen (Replenishment, Hymn of Hope, Shadowfiend, Rapture, etc) and Intellect interacts directly with how mp5 is calculated. It cannot be black and white. Spirit and Intellect interact with each other for how to calculate regen.

The formula I use is:
(INT)^(1/2) * SPI * 0,016725
which is the formula used to calculate out of combat regen.

So here is how I would analyze regen from both procs.

Heartsong:
108 spirit average, with about 4000 intellect gives a "steady" 114 mp5. At 3000 intellect, 99 mp5. And at 5000 intellect it gives 127 mp5. It is not linear but is nearly linear.

Power Torrent:
120 intellect average. Intellect being a root square in the regen equation, its scaling decreases with a fixed amount of spirit. So for a more precise exercise it is necessary to average the total intellect and multiply by the uptime rather than use an average intellect calculation. We therefore need to use fixed spirit and fixed intellect values to properly evaluate intellect regen. I will use 2 sets of fixed values, one of Spirit = 2500 and one of Spirit = 3250.

At Spi = 2500, if Int = 3000, 24% uptime of 500 intellect averages 45 mp5. If Int = 4000, it averages at 39 mp5. If Int = 5000, it averages at 35 mp5.

At Spi = 3250, if Int = 3000, 24% uptime of 500 intellect averages 58 mp5. If Int = 4000, it averages at 51 mp5. If Int = 5000, it averages at 46 mp5.

These calculations are for "mp5" regen only. Replenishment would give a 37,5 additional mp5 when the proc is up, for an average of 9 mp5. The list can be long and I will not go in the details of other mana-based regen abilities. But it all adds up. If Rapture was used every time it is available, it would give 45 mp5. For a disc priest, with 4k intellect and 3,25k spirit, this would end up providing at least 79 in combat mp5. When Heartsong would provide 57 in combat mp5.

Throughput can also be considered as regen since bigger heals mean less heals to cast and therefore less mana spent. Definitly my enchant of choice for Cata.

Thank you.

TL;DR version: Power Torrent is nearly on par for regen for certain healers while being a very powerful throughput proc. It is probably a wise case to favor it over Heartsong. At least when Maelstrom Crystals are less expensive... Hurricane was not considered since it is purely a burst healing and/or dps proc.

Apparently, Heartsong proc IS calculated for Mana Tide :)

Things a healer should consider

Druid: Rarely have any mana issues, between Furor and Revitalize timing Innervate with Power Torrent is an actual MP5 gain over Heartsong. Power Torrent is the clear winner.

Shaman: Go Heartsong or go home. Shaman have mana issues, every single piece of shaman equipment (bar trinkets) should have spirit on it. Plus unlike most trinket on-use/procs, this DOES affect Mana Tide Totem.

Paladin: Similar to Druid, this class rarely runs out of mana. Most of it's means of mana regeneration are based on the total pool so Power Torrent gives them the edge.

Priest: Another class with regeneration based on total mana, Enlightenment makes Power Torrent the absolute winner for Discipline. For Holy it comes down to preference. Holy tends to consume more mana than Discipline henceforth the constant mana pump from Heartsong might be preferred.

Other more things to keep in mind are Replenishment and meta gem, Power Torrent benefits those while Heartsong does not.

While I was in the Maw of Isorath, Twilight Highlands, I wasn't casting a thing yet Heartsong kept on proccing. I believe, for some reason, the Digestive Juice debuff started proccing it. Very strange, indeed, that it would proc off of a DoT on me, instead of an HoT. ... They may fix it soon, I figure.
