Q:LOL excavator how to play, specific loading and playing? One hundred
Go out with bare out, this way can be such a seemingly die jungler routine is quite popular in hanbok, is after the blue BUFF/ red BUFF cleared F4 home can be just a red and enchant jungler knife (jungler knife you can choose different)The Desolator speed will be greatly faster than the other, and the other end up red and blue BUFF GANK wave after the need to go home and update equipment, then can come up with some things in line by this time.E skills in full of anger state unearthed caused the 100% true damage plus 10% disciplinary damage plus 2 seconds slow enough to kill the other heroes, such a routine once our previous playing field advantage will be great, but disadvantage is that the other once we find the anti wild will be very hurt, is the so-called high risk in return, the pros and cons of is your choice of game insight has been decisive judgment.The rundown is more suitable for lake south equipment, because although Lexus launched GANK game by surprise but only a hit skill is difficult to retain the opponent, so it will be broken slows the price is high.Electric knife is also a good choice, because full anger fixed damage, with the effect of electric knife can be imagined. Is the favorite Lake South LAN equipment, improve the speed in digging will make them impossible to guard against their own blood and material and the range of resistance. I recommend enchant the selection of soldiers, compared with cunning attack speed and magic damage fighters enchant would be more suitable for the lake south, after all lake south by flat A is far from the actual output a fixed full of anger to harm.The choice of life insurance is the Banshee veil, because the veil of effect is likely to let the thunder for the time to escape the facility. After all, the recommended output equipment. Group war light language can let us play good harm (more extreme).
