Recently finished PoE1 and am looking to start Deadfire. I've been playing around with the Battlemage Unbroken/Illusionist or Unbroken/Enchanter idea. I want to be a front line support/debuff/tank. Im open to other subclass combinations but really like the battlemage thematically. I also would like to play sword and board. Not trying to min max but what would my stat spread look like for a build like this and any recommended skills?

No subclass or blood mage is way to go bro. Trust me you ll be upset when you cannot cast some good spells later in your run if you go with that subclasses.

Wizard subclasses are fine if you look ahead and see what spells you're locked out of. You can always cover locked spells thru a companion/adventurer. But if Illusionist is what you wanted, a trickster Rogue for multiclass gets several Illusion spells for free that cost Guile to cast and you have all the base Rogue abilities that can debuff enemies. It's only a 10% downgrade in sneak atk dmg compared to no subclass. Rogue and Fighter both have options to displace themselves/enemies/allies and between Fighter stances and Rogue passives, you can contribute dps easily.

Skills are gonna be whatever you prefer. Athletics is a cheap heal option, Arcana if you want to use scrolls to get more of the battlemage vibe. Explosives can be nice on a Fighter because they get buffed by the hit conversion bonus they get so soon.
