What to bring to a TBC raid

Pick a spec and see what to bring to a raid — flask, food, potions, oils and the rest — with the reason each one is on the list. It is a checklist, not a measurement, and the page says exactly whose checklist it is: Wowhead's own recommendations for that spec, transcribed with the guide's title credited under every list.

Pick your spec, because a shaman's flask is not a rogue's, then read the “why” beside each line — it is the guide's own reasoning, and it is the part that tells you whether a line applies to your night. Hover an item for its effect text or follow it out to Wowhead; a name with a dotted underline has no item id in any table this site ships, so it opens a Wowhead search rather than the wrong item confidently.
