When I first began playing WoW, I became a Druid. I chose this class because I wanted to heal. The trouble is, I wasn't very good at it, so this guide is designed to help you heal at a low level on a druid. First, I will talk you through a few useful spells.
Healing Spells
Healing Touch: Your basic healing spell. Has a 1.5 second cast at the start, which increases to 3.5, so make sure that you don't use this at the last minute.
Rejuvenation: Instant cast Healing-Over-Time spell. You might want to put this on the tank at the start of a big pull or boss, just to be safe. This spell can be effective if used properly, as you can put this on whoever is losing health, and then Healing Touch.
Regrowth: Probably my favourite healing spell in the Druid's arsenal, as it has a fast cast time, and it heals both instant and over-time. Very useful for making sure a tank stays alive. What you might want to do in a very big pull is, put Rejuvenation on the tank, followed by this, followed by Healing Touch.
Cure Poison: Does exactly what it says on the tin.
Rebirth: Druid ressurection spell. Fast cast time, can be used in combat, BUT it has a 20 Minute Cooldown and take Regeants. If everybody but you dies, make sure you Ressurect another healer to get the rest Live and Kicking!
Abolish Poison: Exactly the same as Cure Poison, but this makes you lose poison effects for 8 seconds afterwards.
Remove Curse: Dispells a curse...
Tranquillity: VERY useful spell when used correctly. It's an AoE healing spell, with high mana cost, high threat and 10 minute cooldown. Really if you want to use this spell you should invest two talent points in Improved Tranquillity, which will basically delete the Threat.
Lifebloom: Don't get this spell till level 64, so I have never used it. Basically, it is an instant cast Healing-Over-Time that when the duration finishes, it heals the target. Kind of like a Backwards Regrowth.
Buff Spells
Mark of the Wild: Your basic Buff. Gives the Target Armour, Stats and Reistance. What more could you ask?
Thorns: Makes anyone that hits you hurt. Very low damage, I don't know why I bother using it.
Gift of the Wild Don't learn till 50. Just a better version of Mark of the Wild.
So that just about covers all the spells you'll need for healing in Instances. Let's move onto Gear now.
Gear
For a Healer I reccommened HIGH Intellect, and HIGH Spirit. Also you might want to get some +Healing items. But while you're concentrating on these stats, make sure you get some Stamina (to make sure you stay alive).
Weapon: For a weapon I suggest a staff, as they mainly have good Intellect and Spirit boosts.
Armour: As far as armour goes, all a Druid needs is Leather. Some Druid healers like to get cloth gloves and/or boots, because they have the least armour in the first place, but I prefer to just stik to Leather. If your buying things off the AH, I recommend that Armour is the last thing you look at, but that doesn't mean you should completly neglect it.
Rings/Necklace: I tend to get +Healing and Damage spells on my rings, and just normal stats on Necklace, No real reason for that, it's just what I do.
Trinkets: If you're getting a Trinket, you have to ask yourself 'Am I actully going to use this?' because most Trinkets you have to use. I stay away from the Use ones, and try to focus on the Equip ones.
