As a responsible raider, you should carry with you a bag of consumables. Alongside an assortment of Elixirs and foodstuffs, you should have a few stacks of Mana Potions. Mana Potions come in all shapes and sizes (but Alchemist Regulation apparently requires the addition of FD&C Blue 1) and from a variety of sources. To give you an idea, I regularly carry 15 Super Mana Potions, 10 Combat Mana Potions, and 5 or more Unstable Mana Potions. However, I’ve recently added a new type of Mana Potion to my arsenal — the Fel Mana Potion:

The Good: The Fel Mana Potion grants its imbiber 3200 Mana over 24 seconds. Compare that to the values for it’s closest equivalent, the Super Mana Potion, which ranges from 1800 to 3000 Mana (average 2400) and delivers instantly. That represents an average percent increase of 33% (with a maximum increase of 78% if you were really unlucky)!
The Bad: Because many people are turned off by the reduction of spell damage and healing, these are less commonly created by alchemists. Hunters, however, love them since they aren’t affected by the potion’s drawbacks. Consequently, it may be harder to find them on the Auction House. I recommend buying the materials and having them crafted in batches, preferably by a Potion Master you’ve schmoozed into giving you the extras.
The Ugly: Ugly because it involves math, not because it’s a serious drawback. I hope to demonstrate that, while the 15-minute reduction of +Healing by 50 might sound horrible, the extra mana gained more than offsets it, at least when used later in the fight. After all, most would agree that losing +50 Healing over 60 seconds is worth gaining an average of an additional 800 Mana (and a maximum of 1800) over that same time period:
((3200 - 1800) + (3200 - 3000))/2 = 800
To determine when it’s appropriate to use a Fel Mana Potion instead of a Super Mana Potion, we need to compare the relative values placed upon MP5 and +Healing. This will vary based upon your method of healing, and I demonstrate how to perform this calculation for yourself in the earlier MP5 vs. Healing article. The MP5 of these potions is determined by the amount of time remaining in the encounter. The shorter the amount of time remaining in an encounter, the greater the MP5 afforded by a Fel Mana Potion:
MP5FMP = 3200 Mana/t
Because the value of +Healing vs. MP5 varies by fight and the method by which you heal, we will evaluate the comparative value of FMPs vs. SMPs for different ratios and based on different amounts of time remaining until the encounter concludes (at which point, the +Healing debuff will no longer matter). In performing this calculation, we have to subtract the equivalent value of MP5 from any +Healing that’s lost due to the Fel Weakness debuff (which lasts 15 minutes or until death). Here’s the formula used:
Mana GainFMP = Mana return from FMP - Mana equivalent lost due to Fel Weakness over remaining fight duration OR
Mana GainFMP = 3200 - ((50/Value of +Healing equal to 1 MP5) * 12 * (Minutes Remaining))
I used the 11 +Healing = 1 MP5 value derived in my previous article. I also graphed 6 +Healing = 1 MP5 and 18 +Healing = 1 MP5 for the sake of contrast (and because this value does vary by encounter). I measured the return when used with 1 minute remaining to 15 minutes remaining (at which point the debuff expires). I also graphed the average mana return of a Super Mana Potion (2400):

From the figure above, we can see that, at the value of +Healing vs. MP5 calculated previously (11 +Healing = 1 MP5), the total mana return from a Fel Mana Potion exceeds that of an average Super Mana Potion even when the fight lasts almost the entire duration of the Fel Weakness buff! At a more conservative estimate (6 +Healing = 1 MP5), it’s still advantageous to use a Fel Mana Potion rather than a Super Mana Potion as long as there are 8 or fewer minutes remaining in the fight. Keep in mind that the Fel Weakness buff stacks up to 7 times, but if the tradeoff is a wise one to make the first time, it should subsequently be a wise one to make for additional debuff applications (since essentially nothing about the tradeoff changes). (However, studies indicate that repeated consumption of Fel Mana Potions may cause liver damage in rats. But those rats were from Gnomergan and had a liver to spare.)
Additional Considerations
To properly leverage a Fel Mana Potion, you must anticipate needing the mana well in advance since, unlike the Super Mana Potion, the restoration is not immediate and takes place over 24 seconds. Druids are experienced at anticipating the use of Innervate, however, and should find this caveat no great hardship.
Finally, as pointed out by commentor, Mike, while the threat associated with the consumption of a Super Mana Potion is an immediate 900-1500, the threat that would be garnered from the consumption of a Fel Mana potion would be a gradual 67 threat per second for 24 seconds. This figure is more manageable for tanks than a 900-1500 Threat spike.

God Bless the Skettis escort unstable pots and Moroe’s Lucky Pocketwatch + Badge of Tenacity. A powershift and a pot pop has saved my furry butt many a time.

Could using Elixir of Healing Power be a way to compensate for the Fel Mana’s debuff? Then, after taking the Fel Mana pot, you’re only down to your original +healing from gear for those 15 minutes.

@Aiuriun: I forgot for a moment that you recently specced to Feral and had to wonder why you referred to your butt as “furry” … Unpleasant mental image, to be sure.
@Gillir: That’s a really great idea. I mean, ideally you’d already be using one of those potions, right? Right? But if you’re being a slacker (!), it would definitely be a good idea to pair these up. =) Better yet, drink a Major Mageblood! Even better, drink both (one’s Guardian, the other Battle so they’ll stack).
@Chris: Awesome! And I love the picture you used! /jealous
yep… prepare yourself Phae, WoW Insider has your Fel Mana Potions on their front page…. lol.
You know you’re doing something right when people keep wanting to send other folks your way
@Phaelia: Glad you like it! I’ve gotten a couple of compliments on the pictures I use with my posts and they’re always nice to hear. I have fun making them.
@bigbearbutt: I try to share the love with my fellow bloggers, especially when they’ve got something important to say.
No wonder that you didn’t get the threat sorted out. You missed the biggest fact, that we tanks love when you drink that stuff:

http://www.wowwiki.com/Threat
1 Pt Mana gained = 0.5 Threat
I read that like drinking a 3000 Mana Potion gives you immediatly 1500 Threat. When threat is already tight (and you may even stand in the 110% Range), this may give you immediatly aggro …
Drinking a Fel Mana Potion gives you 65 TPS (which a tank can easily top), while reducing the Threat done thru Damage or Healing.
That IS nice …

Oops…sorry Phae
Do we know if this pot is affected by an Alchemist’s Stone?
Yes, it is affected by the Alchemist’s Stone, granting 4480 mana over 24 seconds.
@Mike: That is an interesting point about the threat gain associated with one of these potions and how it’s incremental instead of burst! Maybe not such a big issue on boss fights (since it’s rare that I see healers pull aggro on anything other than trash), but pretty awesome nonetheless!
