【进阶实战】Lua保底计数：强化第10次必成的垫刀机制

local function enhance(actor)
    if math.random(1, 10) == 1 then
        setplayvar(actor, "LV_UP", 1)   -- 纯随机，27连败无兜底
    end
end

local function enhance(actor)
    local pity = getplayvar(actor, "PITY") or 0
    if pity >= 9 or math.random(1, 10) == 1 then
        setplayvar(actor, "PITY", 0)
        setplayvar(actor, "LV_UP", 1)
        sendmsg(actor, 1, "烈火剑法强化成功"
            .. (pity >= 9 and "（保底）" or ""))
    else
        setplayvar(actor, "PITY", pity + 1)
        sendmsg(actor, 1, "失败，保底进度 " .. (pity + 1) .. "/10")
    end
