Any race or alignement restrictions?
Actually no. You can not substitude a spell for one of your four attacks. You can do a single attack after either casting a cantrip or spell (depending on your level), but then you are not using the attack action and get not extra attacks. Or you use the attack action, but then you get no spells. You can never substitue a spell for one of your four attacks4 possible attacks per action, you can move between them, and you can substitute a Shove, Grapple, Cantrip, or Spell by level 20,
Awesome. As I said, I need my PHB and I need it NOW!There are no race/alignment, or any kind of restrictions in the game. If you can justify it in your game, you can play it. Drow Priestess with the Healing domain? Done. LN Paladin of Vengeance? Easy. Lawful Good Indiana Jones type Rogue? In the book.
There is no Bastard Sword, only a Long sword that can be weilded 2handed for 1d10 instead of one handed for 1d8. I didn't see any other weapon/armor restrictions so you can be in full plate and cast spells from level 3 on.
Watching a PF Magus with nothing but shocking grasp prepared murder every thing in the first round had soured me on the class, but the 5E EK looks a damn sight better than the 3.5 version, which I felt was lackluster.
That said, you can very easily multiclass into wizard after picking up your second attack at level 5 and seriously augment your casting ability if you so choose.If you go with school of abjuration you can actually create a ward like the 4e swordmage and use it to intervene when an enemy hits your allies.
The valor bard, the oath of vengeance paladin, and the pact blade warlock are other good options for the warrior/mage archetype. 5e offers a lot of options in this category.
