Let me highlight some of the key gameplay elements: make char with base stats, equip weapon, kill stuff, get
gear, wear
gear, find skill gem (this is how the game gives you spells or
abilities, these can be socketed into gem slots in your
gear to be ready to use), skill gem level up along with character,
assign passive in character skill tree, kills monsters and fine orbs (these are the currency used in the game that can have various uses like increasing quality or respecting items etc.), join party (up to 6) and kill mobs, trade loot.
