Hello everyone!
I never played WoW classic, and it’s my first time as mage.
I would like to know your opinions on how to build it. Frost, arcane or fire.
If you can, pros and cons and a nice talents build that you recommend it in this classic world!
Thank you and love
Check out wowhead. For leveling and raiding, frost tends to be the best.
Mages are the greatest. We have good DPS, CC, AoE, curse removal, we make food and drinks, we blink, we teleport and port, and also we’re smexy.
Leveling as frost is what I recommend. You can slow everything, have good AoE and escaping is easier when you’re caught with more mobs than you can handle.
The real question is: how can you NOT play mage? Anything less would be uncivilized.
Frost, go improved blizzard if you want to AoE grind, improved frost nova/shatter if you want to have PvP viability while leveling, Frostbite for pure single target questing/pvping.
Build around how you’ll end up playing, my build is a tribrid between Single target, aoe mob grinding and PvP so I can do all of them reasonably well without respeccing.
With the 1.12 talents, frost is head and shoulders above the other specs until Naxx.
you press fireball, then another fireball, and then another fireball. if you’re oom then you wand, until you can fireball again.
You, PEW PEW PEW

When you in a 5 man you must always blizzard when there are two or less mobs, Its really Mana efficient.
Always make sure that you frost Nova mobs you agro when they run by the healer, after all parties love mobs being forced to hit the healer as you run to safety.
Also if Frost Nova is on CD, never blink to the tank. Always run far from the tank as you can as the mobs chase you, tanks love that. After all they are not taking damage.
Honestly - just google “WoW Classic Frost Mage Leveling”.
Icy Veins has you covered by experts. They’ll give you all you need to know.
I think it’s worth mentioning that if you go into blizzard for aoe you only need 2/3 so you aren’t overwriting cone of cold slow. CoC slow lasts longer giving you more time to make distance that just the 4s blizzard slow, and with the heartbeat aoe tick thing unlike retail where it just starts immediately, if a nova breaks early the mob could be all the way through your blizzard before it gets slowed by it.
But in general you can just dump all your talent points into frost and be alright, there aren’t really any “bad” choices except frostbite, which is still really good for pvp, but can cause issues with random novas in dungeons (ie, you accidentally proc a nova with a frostbolt right beside your healer and the mob vicinity agros and 1 shots him with unlucky crits/mob windfury)
Edit,
Efficient no, but the funny thing is at certain levels blizzard on 2 mobs will be higher dps than frostbolt spam
Actually, you only really need 1 point in that Blizzard slow … and you need that to activate the Shatter ability for Blizzard.
You would pull, Frost Nova, Flame Pillar … Blizzard … and when stuff gets too close(in solo play) Arcane Explosion and Cone of Cold … Blink.
Otherwise like Zerve said here nicely … you can’t be that wrong to dump most points into the Frost Tree, especially the last Talent helps.
Later at 60 you can do different Builds, 3min Mage and what not. But thats not important for leveling.
As stated, go heavy on frost talents. I’d say it’s worth going into arcane 7 points for wand spec while leveling.
Your life will be infinitely easier if you get a wand as soon as possible. I would also recommend building for sustainability while leveling, Arcane.
Keep in mind that you are NOT locked into a specialization in Classic. Use your spells based on the circumstances, not based on where you are putting talent points. Too many people think they have to use only one school of magic because they are putting their talents in that tree, which makes the gameplay boring and inefficient.
Also, look for talents that reduce a mob’s chance to resist your spells. It helps, a lot.
Finally, frost nova and blink are your friends. Anything you can do to put distance between you and your target until you have worn them down will hel you out. Mages are glass canons.
So basically frost is the king.
As for talents, what’s the numbers?
Like x-y-z that are nice for lvling.
If I understood well, I can change it later on (I hope) so at least I’ll level fast.
Ya, mobs>flamestrike>CoC shatter>ae spam will be higher dps, it just makes mana management more difficult and is generally riskier. Tbh when I’m in dungeon groups it all depends on how the pulls are going. If it’s kind of messy I’m just going to max range blizzard spam, if everything is grouped tight, the tank isn’t getting rekt and there aren’t mobs grouping up late, I’ll go for more min/max damage since there’s less risk.
I definitely prefer to aoe in the manner you described, but at low levels with crap gear just pressing blizzard has a way lower risk:reward
To the question above, if you plan on mostly solo leveling for sure go 5/5 imp frostbolt first. But if you’re just mostly going to be dungeon grinding you don’t really need it. It’s hard to say what the “best” path is because you’re always going to feel like you want/need more talents than you have points for. My only suggestion would be to not take frostwarding/frostbite while leveling, literally every other choice is good
