Making a breton spell sword. As far as combat goes im using light armor/1h/archery/smithing. But how do i go about doing the magic part? How should i divi up the magica/health/stamina. Also im starting on master so im afraid of NOT putting everything into health. Any tips?

I'm guess 4/2/1 Health/Magicka/Stamina, you can flip magicka and stamina if you're going for a more melee leaning spellsword.

sounds good, though i will be using more physical attacks than magica

Save the stamina for later, and focus on building magicka and health first. You only need 1 stamina point to powerattack anyway. Since you're on master I'd suggest go with a shield as well, you don't need to perk it but having block as a secondary skill is great when out of magicka, especially when facing two-handers, and if you're going to be focusing on physical attacks. You also get one extra piece to enchant as well as the extra armor. If you're on pc you can hot key the shield and it will be seamless.

As for spells Destruction for ranged and supplementary damage, a one handed weapon of what you like the most. Restoration should be almost fully perked (don't get the extra life and dual casting) especially get respite as early on as possible. If you want you can add alteration for some utility spells like paralyze but that's entirely up to you (good crowd control though)
