Vampire Sword: 50% attacks back to blood. In fact, simply speaking, only physical attacks can restore blood. But in Genting's game, most of the hero's skills are magical damage. So there are very few heroes who really use bloodsucking swords, one is Draven and the other is poodle. As for other swordsmen, even the heroes of physics department are more and more compatible with science and technology guns, because they can use blood back and forth technically.
Technology gun: 33% of attacks are blood return. Seeing this "all attacks", we may think that unless physical damage is magic damage, we will only use technology guns when using technology. But in fact, this idea is very one-sided. Why? Because in Genting game, besides physical damage and magic damage, there are also equipment damage and real damage, which can be returned to blood through science and technology guns.
Why is it much bigger in theory? This is because, in fact, the hero Vayne is not strong. Unless the next version is enhanced, it can barely be played. Otherwise, in this version of the void, even if the equipment is prepared for Vayne, it is a waste of time.
