The Wayshrines and the Altars do not restore my character's magic
Must be the OOO mod. I am glad about this though, it would of made it too easy.
Not as easy as you think. It's too bad about the Wayshrines, those are huge helpers in the wilderness. Mine still work at level 14, as I've avoided all topics of conversation about the Prophet.
I have a current DiD warrior Atronach, four majors only. Alchemy is a big part of your life.
flax seeds and steel blue entoloma
You can eat flax raw, for a surprising boost to your magicka.... it's not a little bit, it's a good substantial amount of magicka
My knight, doesn't get back to base for days, weeks at a time. So we've decided to carry a mortar and pestle. While the potions are not as strong as they are when we are back at base with ALL of our alchemical apparati, it does the job.
Combine the above two for awesome restore magicka
Also,
Flax seeds, Steel Blue Entoloma, Summer Bolete will give you restore magicka and a shield
Entoloma and Stinkhorn will also give you restore magicka
you will also need to know that
Cairn Bolete and Lavender or Dragon's Tongue or Aloe Vera or Fly Amanita Cap will give you Restore Health, which is good, as you will be able to save your magicka for when you really need it.
You will pray for the time that you are high enough in level that you will see the will o wisp. You will want one as a pet. Just make sure you either have in potion or spell form: Restore Willpower and Restore Intelligence.
Get awesome training at the Chapel.
If you still get the bonus at the wayshrines, if you activate the god's individual altar and not the main one in any chapel, you can replenish your magicka about 5 times, before hitting the big one in the middle. I sometimes train my skills here, as magicka usage by my warrior atronach is few and far between. Having a good source of magicka around for training is always welcome, and you can save on your potions.
And lastly, is an exploit, therefore a cheat in my eyes, as it defeats the whole purpose of being an Atronach. So I won't mention it here.
