Vow Stone Anime Vanguards Guide, How to Get & Use!

Rift units are some of the rarest characters you can collect in Anime Vanguards, but getting them usually comes down to luck. Thankfully, the Vow Stone gives players a way to guarantee their Rift reward after completing the required objectives. If you’re planning to farm powerful units like Mahoraga or future Rift-exclusive characters, understanding how the Vow Stone works is essential. This guide explains what the Vow Stone does, how to get one, and the best way to use it efficiently.

What Is the Vow Stone?

The Vow Stone is a special item used during Rift battles. Instead of relying completely on random drops, activating a Vow Stone guarantees that you’ll receive the featured Rift unit once you successfully clear the Rift.

Without a Vow Stone, you’ll need to depend on the normal drop rate, which can take many runs before the unit finally appears. Because of this, many players prefer saving their Rift resources until they can purchase a Vow Stone.

How to Get a Vow Stone

You can obtain a Vow Stone from the Rift Shop by spending Rift Shards. Rift Shards are earned by clearing Rift stages, with higher-level Rifts generally providing better rewards. Continue farming Rift content until you have enough currency to purchase the Vow Stone from the shop. Since Rift Shards are also used for other items, it’s recommended to prioritize buying a Vow Stone first if your goal is unlocking the featured Rift unit.

How to Use the Vow Stone

Using a Vow Stone is simple:

1. Buy the Vow Stone from the Rift Shop.
2. Activate it before entering the featured Rift.
3. Complete the Rift successfully.
4. Defeat the final boss.

After clearing the Rift with an active Vow Stone, you’ll automatically receive the featured Rift unit as your reward. For example, players farming Mahoraga can activate a Vow Stone before starting the Mahoraga Rift to guarantee obtaining the unit upon completion.

Does the Vow Stone Guarantee a Shiny Unit?

No. The Vow Stone only guarantees that you’ll receive the featured Rift unit. The unit’s rarity variants, such as Shiny versions, still follow their normal drop rates. You’ll receive the standard version unless you’re lucky enough to roll the alternate appearance.

When Should You Use a Vow Stone?

Since Rift Shards take time to earn, it’s best to save your Vow Stones for units you actually plan to use.

Good situations to use one include:

• Farming a newly released Rift-exclusive unit.
• Unlocking powerful endgame characters.
• Completing your collection without relying on RNG.
• Skipping long farming sessions for extremely rare drops.

Avoid using a Vow Stone on a unit you aren’t interested in, especially if another Rift update is expected soon.

Is the Vow Stone Worth It?

• For most players, the answer is yes.

While farming enough Rift Shards requires some time, the Vow Stone removes the frustration of repeated unsuccessful runs. Instead of hoping for a lucky drop, you know exactly when you’ll receive the featured unit.

This makes it one of the most valuable purchases in the Rift Shop, especially for players who want to stay caught up with the latest Anime Vanguards updates.

The Vow Stone is one of the best quality-of-life items available for Rift farming in Anime Vanguards. Rather than depending entirely on luck, it lets you guarantee the featured Rift unit after clearing the corresponding Rift.

If you’re planning to collect Mahoraga or future Rift-exclusive characters, saving your Rift Shards for a Vow Stone is usually the smartest investment. It shortens the grind, makes your farming sessions more efficient, and ensures your effort is always rewarded.
