The Eredar Twins are the 4th boss encounter in Sunwell Plateau. As of now, however, guilds cannot access them because of a gate which requires progress from the Shattered Sun Offensive to unlock. As you realm nears the unlocking of this gate, be prepared to invest!
This encounter is an elemental one involving shadow and fire. We’re going to forget about the shadow part here because most guilds attempting this boss will have full shadow resist sets from the Mother Shahraz encounter in Black Temple. However, we can expect them to be less prepared to be taking fire damage.
Therefore, when the top guilds on your realm begin attempting this boss, theyre going to need a heckload of Major Fire Protection Potions. The mats for these are:
1x Primal Fire
1x Mana Thistle
1x Imbued Vial
But we’re going to go ahead and recommend against investing in those mats until more “casual” guilds start attempting the twins. Why, you ask? Because top guilds are more likely to provide their raid members with a Cauldron of Major Fire Protection (similar mats):
2x Primal Fire
7x Mana Thistle
1x Fel Iron Casing : 3x Fel Iron Bar
We’re recommending here to invest in the Mana Thistle and Fel Iron Casings. The reason is, not only are these two materials used in creating all Cauldrons, but the price of Primal Fire, like other Primals, will be affected by many other trends. In addition, the preceding encounter to this one is Felmyst, which involves a significant amount of nature damage (therefore Cauldrons of Major Nature Protection will be needed as well).
Looks like SWP is shaping up to be an elemental consumable heavy raid instance. Time to cash in, amigos.
Risk’ometer: 4

I’m quite wary of the usefulness of cauldrons. 25 people can each get one, and only one, potion from a cauldron. They can’t have more than one potion, even if they are from different cauldrons, either. I don’t know the specifics of the Twins fight, but unless everyone needs one, and only one potion during the fight, or everyone can gather up and grab another potion from a fresh cauldron every couple of minutes during the fight, a cauldron really doesn’t make sense anywhere.
Grand Warlock Alythess, the fire sister) puts fire damage dots on random players throughout the fight, so yes, everyone in the raid will be taking fire damage, and having a potion to absorb that damage would be very useful. The mats for a Cauldron VS a potion is very cheap, and in this fight everyone should have one.
My guild’s in on SWP learning the fights currently.
From past SSC /TK / MH / BT experience, cauldrons are pretty much a must whenever massive AoE / random dots elemental damage is dealt, so yes what you’ve posted is pretty sane advice.
We’re 5/5 in MH and 4/9 in BT and have never used a cauldron, because, while having protection potions is handy, having only one in case you randomly get dotted means that you can’t use any other potions during the fight so that your single protection potion won’t be on cooldown, and if you get a second dot, it won’t help you then, either.
But I guess this answers my question, and some raids do use cauldrons.
