Great macro for mouseover healer for raids!

/cast Renew(Rank 10); Renew(Rank 10); Renew(Rank 10); Renew(Rank 10); Renew(Rank 10)

After patch 2.0, Renews and all HoT's alike stack, so you can have as many renews as priest on your tank,

takes 188% of healing as of wrath, but divides the bonus heal among the ticks. for example if your bonus heal was 1000, it would be 1880/5 for the added value of each tick

How does the crit gets calculated? Does each tick has your crit chance, or is your crit chance divided up as well?

Comment by 479179

The way this heal is calculated has been redone for Cataclysm. The base amount is now the tick value, where spellpower and bonuses are applied. One Renew can have 4, 5, or 6 ticks depending on your haste value. Renew is also will be refreshable with Heal through the Heal Chakra.

Comment by Artea

Just noticed as I was going through my combat logs.

Much to my surprise and pleasure: Each tick has a chance to crit. Quite a good reason for me to invest a few points back into crit rating.

Maybe it's just me, but this seems to be doing LESS healing than it did back in Wrath... was there a Nerf?

This is a really nice spell when fighting Cookie in Deadmines. With around 11-12 stacks of I can get my renews ticking every 0.4 seconds.

Comment by vertigo12

Like many over time effect spells Renew now benefits from Haste and Crit. Aside from the healthy On cast heal from Empowered Renew, I'm wondering if theorycrafters or sims could somehow post a data of how many ticks will happen per every X amount of haste you have.

Comment by 786371

A good thing to keep in mind is that 12.5% haste will give your renew spell an extra tick. the next tick requires 37,5% haste.
If you're holy then just forget since your heal spell will refresh the duration if talented.

Comment by Hairband

I also respectfully disagree. You're refreshing Renews by virtue of your Chakra state. But what kind of Renew is it? Above 12.5 haste, you're getting a bonus 20% healing done over the 12 seconds. Why? Because haste gives you one more SIXTH tick during the 12 seconds, value is at least the same if not greater than the other 5 heals (depending on if you Crit). So many talents in Holy give a boost to your Renew is just seems like a no brainer to put haste on everything except at the cost of Spirit.

Comment by Keldion

I've thrown together a quick spreadsheet calculation of the breakpoints here, Blizzard rounds HOT/DOT ticks to the thousandths; I noticed this behavior in December of last year.

The first extra Renew tick is easy to pick up, but I wouldn't worry about needing any more than that.

Comment by Zaalbeth

The 'Modified by' tab for this page is incorrect - Renew is not affected by State of Mind or Revelations. It is however affected by Rapid Renewal, which is not mentioned.

Comment by vertigo12

Can somebody who's reading this volunteer in doing a research/mathcraft regarding haste requirement for Renew to make additional 5th,6th or even 7th at level 80 and 85?A tabulated reply would be much appreciated. I highly do recommend using this in both Disc /Holy spec if others don't do so.

Chakra Talent - Serenity versus Sanctuary With the Renew Spell
The Holy talent tree has a Chakra talent that benefits the Renew spell considerably.

Chakra - Serenity
All direct healing spells refresh the duration of the Renew spell when Chakra - Serenity is active. This includes Power Word: Shield. The Renew spell is commonly cast on targets along with Power Word: Shield to heal and absorb damage over time. If cast appropriately with your other heals, this can save you time and mana. Additionally, Chakra - Serenity increases the crit chance of all your direct healing spells, including Renew, by 10%.
When Chakra - Serenity is active, you can cast Holy Word: Serenity, which will also refresh your Renew spell. This spell costs significantly less mana and does greater healing than the Heal spell, is cast instantly, and increases the crit chance of your healing spells by 25% for six seconds.

Chakra – Sanctuary
On the other hand, when Chakra - Sanctuary is active, healing done by the Renew spell, and all AoE healing spells, is increased by 15%. Additionally,Chakra - Sanctuary allows Holy Word: Sanctuary to be cast, which is very helpful in situations where players are stacked together.

My personal preference is to use Chakra - Sanctuary for healing raids and battlegrounds, and use Chakra - Serenity for 5-man dungeons. The exception to this is when I am healing a 5-man dungeon where all three of the DPS players are melee fighters. I use Chakra - Sanctuary in these situations to allow me to cast Holy Word: Sanctuary on the melee group.

The Effect of Haste Buffs on Renew - The Threshold Debate

Regarding the below, excerpted comment, I don’t believe that circumstantially applied buffs can be consistently relied upon to get to a 5th tick during the Renew period of 12 seconds for Haste below 12.5%; however, after reading the quoted conjecture, I am curious if it would be worthwhile to have haste greater than 12.5% to get to a 6th tick from renew, when buffs are applied.

My haste is at exactly 12.57%, which is as close to 12.5% as I could get it without going under the threshold. This is to ensure that I get the 5th tick during the duration of Renew, applying an additional amount of healing during the time. I assume that the great amount of Haste (37.5%) needed to get to a 6th tick during the period is an unworthy pursuit even with raid buffs; therefore, my supposition has been that anything over 12.5% haste would be better spent on Spirit, Mastery or Crit. Is anyone aware of the feasibility of actually getting to a 6th tick while in a large raid with several buffs applied?

I believe that this would be very helpful for many priests to take into consideration when selecting. enchanting, gemming and re-forging their gear.

As a Holy priest, I find Mastery to be a more considerable stat to elevate Echo of Light, once the threshold of haste is established, and a healthy amount Spirit is stacked for battle regeneration of mana.

I should mention that Haste is useful for more than just the amount of healing ticks applied during the Renew spell period, for example:

It increases the speed of delivery for Hymn of Hope, thereby increasing the number of ticks where mana is gained.
Haste increases the speed of delivery for my most valued spell, Divine Hymn, which also increases the ticks of health gained. Note: Divine Hymn now has a maximum of 20 heals.
Haste also reduces the GCD (Global Cooldown) from 1.5 seconds down to as low as 1 second. So, on a positive note, it increases the number of heals that you can jam into a fight encounter. On a negative note, with haste increasing the speed at which you can jam away at your heals, you may burn through your mana a lot faster. especially during long raid encounters. Therefore, it is important to have a healthy balance between Haste and Spirit, as Spirit increases the rate at which you generate mana.

Note: It takes a haste rating of 1693.5 to reduce the GCD to 1 second. With my Haste stacked at 12.57%, I don't encounter any problems with my GCD. For example, when Flash Healing a fast dying target, I am able to trigger the spell at a rate that is comfortable for me. The same holds true for other instant cast spells like my favorite fun spell: Holy Nova (which is great for killing trogs).

Below is the excerpt that got me questioning the value of haste buffs on the Renew spell:

ghell on 2011/01/23 (Patch 4.0.3)
The theorycrafting consensus for haste and renew plateaus in cataclysm is a bit off, so take any theorycrafting you read with a pinch of salt. The current consensus is that 12.5% haste will give a 5th tick and 37.5% haste will give a 6th tick. However, I can get a 5th tick somewhere between 12.0 and 12.4, and the 5% spell haste raid buff (mind quickening, wrath of the air totem, moonkin form) pushes me up to a 6th tick long before 37.5% haste. This means the current formula people are using is just plain wrong, but everyone assuming it is right without checking means that nobody has posted a report

Comment by Tommassive

Renew Haste Breakpoints as of 5.2
To gain the 5th tick of renew at lv90 you will need the following amounts of haste.

Non Goblin
With Haste Raid Buffs 3039
Solo 5313

Goblin
With Haste Raid Buffs 2588
Solo 4843

Those numbers will take you to 12.51%. Which is slightly over the required 12.50% for the extra tick. Haste is multiplicative as you stack it so it is slightly hard to calculate. These seem to be the generally agreed upon numbers, just go with them :P
