What counts as a hit
On hit means a basic attack hit. Each melee swing restores Concentration once, on the first enemy it hits, and each ranged basic attack shot once when it lands. No spell restores it.
One hit restores Memory x 18 / 60, plus your Concentration On Hit. Concentration Regen bonuses raise the Memory part.
How Spell Haste works
A cooldown becomes cooldown x 100 / (100 + Spell Haste). 100 Spell Haste halves every cooldown. It also shortens charge recharge. Your race's dash and defensive spells keep their full cooldown.
Big node or small node

The frame size is only drawn on the tree screen. The game adds each node's own stat lines, whatever its frame, so a big node gives exactly what its lines say.
