Build concept a melee mage. (No weapon's)

[Sir cryosin]

So I was thinking of making a melee mage. I was thinking of warlock 3 pact of the Tome picking the Druid cantrip from UA Primal Savagery. I was thinking of starting as stone sorcerer for con for AC and con saves. Then warlock tell 3lv then finished off in Sorcerer.

My concept is a mage the argument his physical capabilities with magic. But will drop a few other spells here and there.
