So, it wants me to use Lunge, Rebuke, Holy Aura, Symbol of Hope, and Warpath. But the tree wants me to use Smite? What’s the for? It seems like a waste of a tree slot. Maybe i’m wrong ? Maybe for the balance buffs?
Smite is cast automatically (which is why it’s not on your skill bar and you have an unspecced movement skill instead)…
It does 2 things, namely it heals you, and it gives you a boost to melee fire damage and attack speed as long as a smite hit an enemy in the last 4s.
For the level you play in before you get frustrated and quit, most of them are good enough. You should try to use leveling guides instead, since you rarely get to endgame.
Although, as I said before, you should consider playing D3. It’s more straightforward and streamlines. While the gear choices are kinda similar, they’re also more limited, so it should be easier for you to grasp.
It’s an entry point to the genre, basically.
