Level 1 - fires a ball of shrapnel into the air above the sniper , which promptly explodes into 8 pellets which shower random points in the target area for 10 - 35 physical damage in a 200 area of effect 一级-往空中发射一发榴弹，随机向目标区域（范围200 ）撒播8个爆炸性的弹片，每个弹片造成10 - 35点的物理伤害。
Level 3 - fires a ball of shrapnel into the air above the sniper , which promptly explodes into 16 pellets which shower random points in the target area for 10 - 35 physical damage in a 200 area of effect 三级-往空中发射一发榴弹，随机向目标区域（范围200 ）撒播16个爆炸性的弹片，每个弹片造成10 - 35点的物理伤害。
Level 4 - fires a ball of shrapnel into the air above the sniper , which promptly explodes into 20 pellets which shower random points in the target area for 10 - 35 physical damage in a 200 area of effect 四级-往空中发射一发榴弹，随机向目标区域（范围200 ）撒播20个爆炸性的弹片，每个弹片造成10 - 35点的物理伤害。
Level 2 - fires a ball of shrapnel into the air above the sniper , which promptly explodes into 12 pellets which shower random points in the target area for 10 - 35 physical damage in a 200 area of effect 二级-往空中发射一发榴弹，随机向目标区域（范围200 ）撒播12个爆炸性的弹片，每个弹片造成10 - 35点的物理伤害。
This paper relies on country 863 project " taking off levelly , two stage to orbit and transatmosphere flight vehicle system design " , research towed flight dynamics primarily , development for our country air launch technology of carrier rocket , offering the essential technological reserve 本论文以国家863项目“水平起飞两级入轨跨大气层飞行器总体设计”为依托，对牵引飞行动力学进行初步研究，为我国研究运载火箭空中发射技术提供必要的技术储备。
