如果我投掷匕首，是不是就能同时使用致命瞄准和食人鱼打击了

[夜歌Nachtlied]

致命瞄准（Deadly Aim，又译致死射击）〔战斗〕
通过减少命中率，你能对准敌人的弱点做出极具威胁的远程攻击。
　　先决条件：敏捷13，基本攻击加值+1。
　　专长效果：你可以选择使所有的远程攻击检定受到-1的减值以换取伤害+2。你的BAB每+4，减值再-1，伤害再+2。你必须在攻击检定前选择使用本专长，效果持续到你的下一轮。本专长对于接触攻击或不造成HP伤害的攻击无效。

食人鱼打击（Piranha Strike）【战斗】
你进行快速的组合打击，牺牲精确度，造成大量致命的小伤口。
        先决条件：武器娴熟，基本攻击加质+1
        专长效果：你使用轻武器时可以选择在命中和战技检定上承受-1的惩罚，使伤害增加2，此加值在你使用副手武器的时候减半，当你的基本攻击加值达到+4和之后每增加4点的时候命中减值上升1点，而伤害增加2点，你必须在攻击前使用此专长，且效果延续到你下一轮开始。此伤害加值不会在碰触攻击或不造成生命值伤害的攻击上生效，食人鱼打击无法和猛力攻击一起使用。

Benefit: When wielding a light weapon, you can choose to take a –1 penalty on all melee attack rolls and combat maneuver checks to gain a +2 bonus on all melee damage rolls. This bonus to damage is halved (–50%) if you are making an attack with an off-hand weapon or secondary natural weapon. When your base attack bonus reaches +4, and for every 4 points thereafter, the penalty increases by –1 and the bonus on damage rolls increases by +2. You must choose to use this feat before the attack roll, and its effects last until your next turn. The bonus damage does not apply to touch attacks or effects that do not deal hit point damage. This feat cannot be used in conjunction with the Power Attack feat.

限定近战

食人鱼打击的翻译中遗漏了近战要求，实际上这个专长仅对近战攻击生效。
