Do note: this is in general. Some consumables need to be stacked more, or be added (spell dmg pots) for certain bosses.
And now to summarize them up with what they do in combination with why they are useful:
-Healing boosting (consumables used for increasing healing done and making you able to use higher/lower ranked heals situationally)
*Flask of Distilled wisdom – this flask is very useful for the usage of innervate on a target without wasting your mana on overheals, but for the rest its just 1 extra major mana potion on your mana pool). Also, with consistently popping major mana runes/dark runes it allows for 1 more wave of popping them without going oom before it.
*Mageblood elixir – this is very useful to have to keep your mana up during fights.
*Cerebral Cortex Compound – very useful to increase your maximum mana pool and thus gives you the opportunity to pop more major mana potions/dark runes in a fight, also more crit.
*Gizzard Gum – increases healing power and mana regen.
*Brilliant mana oil – this is the best Weapon enchant possible, and I highly recommend it.
*Kreeg's Stout Breakdown – + 25 spirit and -5 intellect, giving you more healing bonus and more mana regen at the cost of a minor portion of intellect.
*Nightfin Soup – giving you some mana regeneration.
*Monster Omelette (or any other 12 stam/spirit food) – giving you a boost in your health, mana regenerate and healing bonus (holy talent).
-Survival Boosting (consumables used for staying alive so you can actually cast heals, because you can’t cast them while dead xD)
*Elixir of Fortitude – an useful consumable to keep your health higher.
*Elixir of Superior Defense – useful for fights with adds to boost your armor.
*Major Troll's Blood Potion/Mighty Troll’s Blood Potion – giving you healing without doing anything!
*Long Juice Cocktail – increases survivalability by increasing health.
*Greater Nature/Shadow/Frost/Arcane/Fire Protection potion – protecting you against the specific damage allowing you to heal more comfortably as you are less worried about your own HP.
*Crystal Ward – useful for boosting your armor, same as elixir of greater defense.
*Gift of Arthas – gives some extra shadow resistance and helps reduce dmg of adds in add fights.
*Rumsey Rum Black Label – useful for boosting your hp=staying alive.
*Juju Chill/Ember – good for world pvp fights/fights that deal fire/frost dmg.
- Potions
*Major Mana Potion – giving you your mana back allowing you to do more healing.
*Dark/Demonic Rune – giving you your mana back at the cost of health allowing you to do more healing.
*Whipper Root Tuber – giving your hp back allowing you to stay alive longer. Very useful when mana is not a consideration!
*Crystal Restore – simply free healing at no mana cost, does high healing as well!
*Magic Resistance Potion – reducing damage taken from magic spells -> very useful to pop pre-fights so the potion CD is gone when you need it for mana potions.
*Swiftness Potion – increasing movement speed so we as priests are also able to KITE!!!!! Also very useful for speed runs.
*Limited Invulnerability Potion – a lifesaver! Pop it when you get agro and tanks are slow on reacting to it.
*Invisibility Potion – very useful for sneaking past alliance raids too stupid to use detect lesser invisibility with their warlocks, or generally good to skip npcs in raids that can’t detect you.
*Noggerfogger Elixir – its slow fall effect is nice in any PVP encounter where you jump off something. It is also useful during Anub’Rekhan. Can also be useful if it reduces hitbox on your server.
*Goblin Sapper Charge/Crystal Charge: simply useful to clear things faster as it has no CD.
-Situational (DPS for increasing your damage done for fights like C’thun, survivalability self-evident)
*Flask of the titans – best consumable for staying alive, highly recommended for progression/pvp.
*Greater Arcane Elixir – increasing damage done by all spells, useful for dpsing.
*Elixir of Shadow Power - increasing shadow damage done, useful for dpsing.
*Dirge's Kickin'Chimaerok Chops – giving you a boost in your health.
