基于—frida — 随机强化（@青梅煮酒

第一步：
nums -> 强化等级 16 17 18 19 20
weights -> 权重 越小越难出
function randomNumber() {
	var nums = [16, 17, 18, 19, 20];
	var weights = [1, 0.2, 0.05, 0.03, 0.01];
	var totalWeight = weights.reduce(function (a, b) {
			return a + b;
		}, 0);
	var rnd = Math.random() * totalWeight;
	var sum = 0;
	var result = null;
	for (var i = 0; i < nums.length; i++) {
		sum += weights[i];
		if (rnd < sum) {
			result = nums[i];
			break;
		}
	}
	return result;
}
第二步：
/**
* 随机增幅
*
* @param user 用户
*/

function randomIncrease(user) {

	var inven = CUserCharacInfo_getCurCharacInvenW(user);
	var equ = CInventory_GetInvenRef(inven, INVENTORY_TYPE_ITEM, 9);
	var itemId = Inven_Item_getKey(equ)
	var inUpgrade_level = equ.add(6).readU8();
	var append = equ.add(17).readU16();
	var characName = api_CUserCharacInfo_getCurCharacName(user);
	var equipmentName = api_CItem_GetItemName(itemId);
	if (equ != null) {
		if (append != null && append != 0) {
			if (inUpgrade_level < 31) {
				var now = randomNumber();
				equ.add(6).writeU8(now);
				CUser_SendUpdateItemList(user, 1, 0, 9);
				api_CUser_SendNotiPacketMessage(user, "[" + [characName] + "] 增幅 +" + now + " " + [equipmentName] + "成功", 0);
			} else {
					api_CUser_SendNotiPacketMessage(user, "使用失败：当前装备增幅等级，已到最大限制！", 1);
			}
		} else {
				api_CUser_SendNotiPacketMessage(user, "使用失败：此装备无异界气息！", 1);
		}
	}
}

第三步：
if ('20230726 ' == item_id) {
// 随机增幅 ok
	randomIncrease(user)
}
注：这个道具是随机增幅的 所以它也会降级 比如你现在是 19 你可能一用 就 16了
