Basic Scrolls - Is It Worth It To Buy Them?

I have seen just so many players asking whether or not it’s worth it to buy basic scrolls every day in the shop.

Most of us have already know that it’s definitely not worth it at all.

However, I still want to bring some math here so new players can easily see how unworthy it is.

In short, when compare the received value to the costs of buying basic scrolls, based on the market prices, you usually overpay 40% of the original prices.

In the early stage of the game, purchasing a basic scroll only cost 50K. With a half of the cost, sounds like it’s worth it to do that at the beginning of the game. However, you usually need a lot of gold there. Also, there are more important things to buy with gold rather than spending gold on Basic Scrolls when you’ve started playing the game.

Note: At the first days, you can purchase the Basic Scroll with just 50K-60K Gold. However, after reaching a decent level, it increases to 100K Gold.

Only consider wasting your Gold on Basic Scrolls after maxing your C6 Stones for both PVP and PVE team, maxing all resource buildings on the Celestial Island, having at least 2 Pets and having your Heroes to level 290.

Even when you are at the very late game, you still need tons of Gold to spend on Hero Promotion Stones and Spirits.
