So the evolution of the weapon path until now is like this: mana pathways/veins (increases the efficiency of all the abilities related to the chosen weapon), impose/intent (using the mana from the surroundings you can increase your power or reduce your mana consumption), sword heart/weapon heart/weapon fusion (increases the attack range at a cheap price) and now sword mana(makes ??close range?? attacks free for a certain level and probably unlocks a new set of powers for this new type of mana).
