Q:The soul of darkness, how about the souls on the slopes beside the cursed frogs outside 3 flanges?
4. magic, bow and arrow can only serve as an auxiliary, can not serve as the main force. 5. opening gifts suggest choosing a flame metamorphic gem, the early game (Wangcheng, outer walls and undead streets), 80%-90%'s enemies, weak fire. 6. sword God and God was badly cut chicken. Case: a main broadcast take the sword in the tomb of the dungeon play skeletons, a multi segment, the first under a huge damage, directly to the skull behind the play apart, waving empty, only the skeleton together again. Look at the real egg pain, case two: the 2 generation, giant sword and big chicken legs, when the enemy moves, you can directly put the enemy lying prone. But in this seat, the little monster in the move when the giant sword shot, often against the chop. I suspect that the 3 generation has "hard and direct protection", which is a continuous attack on the same target, and the target will be continuously reduced, which is a bad news for the weapon. Think of the 3 generation of giant weapons compared to the 2 generation, moves and withdrawal are slow. 7. most BOSS do not have "routines" for opportunistic. For example, the 2 generation, many non DLC original BOSS, can be raised to shield the back of the stream, "Lai die", there are several UP with this habit against the three generation of BOSS and small soldier, the result of crazy suffering. Even the ordinary Knight mobs are in your shield around him, he will use a Shield Slam your shield, causing damage prevention, and anti kill!!! BOSS war, against the 2 generation of giant BOSS has a formula called "crotch person", the "best student change, otherwise it will crazy. More than 8. UP anchors said in an interview that the 3 generation of "anti - roll decisions" is the most difficult of all generations
