local function draw(actor)
    if math.random(1, 1000) == 1 then
        giveitem(actor, "裁决之杖", 1, 0, "大奖")   -- 奖额固定无滚存
    end
end

local POOL = 0
local function draw(actor)
    takeitem(actor, "金元", 100)
    POOL = POOL + 50                   -- 每抽注入50
    if math.random(1, 1000) == 1 then
        giveitem(actor, "裁决之杖", 1, 0, "奖池爆发")
        sendmsg(actor, 1, "祖玛教主奖池 " .. POOL .. " 金被捧走")
        POOL = 0                       -- 中奖清零重新滚存
    end
