Which talents are best for mages? thinking about glass-cannon but I'm afraid my mages will get destroyed against range enemies. Currently level 10 in 2nd town.
Glass cannon isn't as great as it used to be, and generally speaking I wouldn't bother. The points you would put in speed you get for "free" from glass cannon, you'll want to put in constitution instead to increase max AP and compensate for health and the result is fairly similar in terms of investment, but you get terrible starting AP with glass cannon(unless you also go perception, but the stat is fairly useless on mages).
You want above all, Far reach, to increase range on all your spells, this is great and definitely the must have for any mage. Elemental Affinity is ok, it's not great unless you setup specifically for it(but that wastes AP in general), but once in a while it'll do great. Specifically if you make it rain on top of yourself you'll get the AP reduction on water spells, and if you get hit you'll generally stand in your own blood, reducing AP for witchcraft.
Other than these 2, you have general talents like Bigger and Better(+1 attribute), All Skilled Up(+2 skill points) and Know it All(+1int but decrease to reputation, not great if the char is the char you do your shopping with but otherwise doesn't matter at all). I would take Bigger and Better for sure but the others are so so.
You also have utility stuff, specifically Light Stepper for perception checks, Pet Pal for all the animal stuff and Scientist if you want to make a mage your crafter(I would say not the best idea since mages can use all their points in spell stuff, while other chars often have spare points, but still).
Then you have school specific stuff if you have 5points. I'd say the Air one is the only one that actually matters though, Fire/Water are pretty poor and Earth is great if you get it very early but it only works in specific parts of the world, and not even that many.
Because mages don't have many "must haves", you can generally pick up a bunch of utility stuff for them instead of other chars. Also if it's one of your main chars, you could go Lone Wolf if you wanted, but losing one char tends to be a worse choice in my opinion with the removal of Lonewolf+Glass Cannon combo.
