With magic its best you focus all your perks into 1 field (Destruction or Conjuration) and all your levels into magicka with some health. As you level up spells become cheaper and as you get perks spells become more powerful aswell as cheaper. But as a mage you are going to die.... and die.... and die.... Until about lvl 20, then you rape all face. Its rather oddd.ghost whistler said:How do companions follow you if you ride a horse?
I dont really understand magic. The game seems to want you to use some, but unless you focus on your magicka score you're going to struggle to use decent spells as you won't have the energy (the description of the spell when you browse a vendor selling spell tomes doesn't say how much the spell costs to cast). I think that physical combat oriented characters are just going to struggle. I came across a foresworn ice mage that could kill me with frost attacks in one hit! THe rest of her allies were nowhere near as powerful!
Is there any point buying a house for 5000gold?
With companions if you lose them simply 'Wait' an hour or so and the spawn at you, and you will lose them, wether you are on a horse or not.
With the house, its a place for storage and some of your companions will wait for you in them, other then that, they are not really worth it. In fact gold is not really worth it; all the best items (with the exlution of low lvl armor) you find anyways. The only thing you really spend money on is spells (or buying houses), but that is only relevent if you cast em.
