【引擎触发】heromagicattack：英雄施法的协同结算

---heromagicattack: 英雄魔法攻击触发
function heromagicattack(self, Target, Hiter, MagicId)
    -- 主人的协同加成：主人在线则英雄法伤 +10%
    local owner = Hero.ownerOf(self)
    if owner and Online.isOnline(owner) then
        local boost = math.floor(Hero.magicOf(self) * 0.1)
        sendmsg(owner, 1, "月灵受到鼓舞，法伤 +" .. boost)
    end
    -- 英雄施法的蓝耗独立结算
    local mp = Hero.mpOf(self)
    if mp < 15 then
        Hero.silent(self)
        sendmsg(owner, 1, "英雄法力不足，进入沉默")
    end
end

---主人施法触发英雄的呼应
function Hero.echo(master, MagicId)
    local lv = Hero.levelOf(master)
    if lv < 25 then return end
    -- 25 级以上：主人施法时英雄 30% 概率跟进同系法术
    if math.random(1, 100) <= 30 then
        Hero.cast(Hero.of(master), MagicId)
        sendmsg(master, 1, "月灵与主人心意相通，跟进施法！")
    end
end
