(note: none of these ‘extra’ sections are totally finished, I’m still adding to them. And yes, at the moment I’ve left out the burning steppes and zanza stuff — they’re both being nerfed in 1.11; and flasks are total overkill 99% of the time)

There are a few special buffs worth getting to speed things up:

• Rallying Cry of the Dragonslayer — when someone turns in the head of Onyxia or Nefarian, everyone nearby receives this buff. +140 AP, 5% physical crit, 10% spell crit
• Spirit of Zandalar — when someone turns in the heart of Hakkar, everyone nearby receives this buff. +15% all stats, +5% dodge, 10% movement speed
• Darkmoon Faire Buffs — A variety of different buffs.
• E’ko & Juju — A quest string in Winterspring starting with Luck Be With You opens up the ability to receive a variety of “Juju” buff items from the NPC there, by turning in various E’ko items that drop from mobs once you’ve done the quest.

And of course, potions and other consumables:

Tanks

• Gift of Arthas — Increases the physical damage a mob takes
• Elixir of Fortitude — +120 Health
• Elixir of Giants — Increases Str by 25 (50 AP)
• Flask of the Titans — +1200 Health (mostly useful when learning new raid encounters. Bit of a waste to use elsewhere. If it’ll make a difference between success and a wipe, use one. Otherwise, don’t)
• Elixir of the Mongoose — Increases crit by 2% and Agility by 25. (3.25% crit, 1.25 Dodge)
• Elixir of Greater Agility — Increases Agility by 25. Does NOT stack with Mongoose. (1.25% crit, 1.25% dodge) — this is much cheaper than Mongoose and provides identical avoidance, just not so much threat creation.
• Elixir of Superior Defense — +450 Armor (greater is 250 and much less expensive)
• Healthstone — Heals for 1200/1320/1440 (talk nice to your warlocks… have one spec only 1 point into improved healthstones and you can carry 3 of them at once for long encounters)
• Dirge’s Kickin’ Chimaerok Chops — +25 Sta for 15 minutes. Otherwise, any +12Sta/Spi food.
• NOT Elixir of Brute Force — This does NOT stack with Prayer of Fortitude, and it does NOT stack with Elixir of Giants, which is considerably cheaper to make and more powerful. It’s a potion that’s good only for soloing.
