I was having difficulty understanding how the damage of my Lightning calculated. It seems I used the wrong base damage to multiply synergy bonus, because every website list the damage of level 1 Lightning as 1-43, but the actual base damage is 1-40 (1-43 / 1.08). If my guess is right, this is due to Lightning is only unlocked after Charged Bolt is allocated, so when you allocate Lightning, you at least have level 1 synergy from Charged Bolt, resulting the synergized damage being displayed . I wonder if anyone have information about the real base damage of skills or the skill damage formula in relation to level?

Amazon Basin will show you the base damage of skills before any synergies.
