1. Exchange your PEN (V) Naru gear for Tuvala weapons and defense gear.

You can exchange your PEN (V) Naru gear for PRI (I) Tuvala gear, which lets you skip the process of enhancing Tuvala gear through 0 to +15 enhancement levels.
Therefore, it is more efficient to exchange your PEN (V) Naru main weapon, sub-weapon, helmet, armor, gloves, and shoes into PRI (I) Tuvala gear.
Upon completing your Awakening and/or Succession questline after reaching Lv. 56, you will be rewarded with your very own PRI (I) Tuvala awakening weapon.

2. Utilize "Enhancement Chance (Stacks)" and "Naderr's Band."

Enhancing any piece of gear utilizes a system of "Enhancement Chance," where "stacks" are built over successive enhancement attempts.
The higher the stack, the greater the chance for successfully enhancing a piece of gear. You can also increase your odds by exchanging Black Stones or using items such as Advice of Valks and Valks' Cry.
Failing enhancements will continuously increase your overall stack, which you may want to save to use for enhancing gear with lower success rates via Naderr's Band.

Please check the [Enhancement] page for the basics of this feature.

You will be able to enhance your Tuvala gear with a 100% sucess probability from PRI (I), DUO (II) and TRI (III).

When trying to ehnace from TET (IV) to PEN (V), the item might have a chance to fail and downgrade back to TRI (III).

4. Use the Frozen Tides Black Stone to enhance from TET (IV) → PEN (V).

You can obtain "Frozen Tides Black Stones" from the Season Pass or by completing the seasonal version of the Atoraxxion dungeon. They guarantee successful enhancement of Tvuala gear up to PEN (V).
Therefore, it is most effective to use these stones to enhance your Tuvala gear from TET (IV) to PEN (V).

5. Failing to enhance accessories will destroy them! Loads of Time-filled Black Stones are required!

Unlike Tuvala weapons and defense gear, Tuvala accessories can only be enhanced with the same type of accessory. (Ex: Tuvala Rings require another Tuvala Ring to enhance) 
Therefore, you will need several of the same accessory type to enhance Tuvala accessories, which in turn will require a decent amount of Time-filled Black Stones.

6. Obtain Advice of Valks through the Season Pass.

Complete Season Pass challenges to obtain Advice of Valks items.
These are simple challenges that require your season character to equip a piece of Tuvala gear enhanced to the appropriate level, so do not miss out!

7. Find a party for "Rift's Echo".

The Rift's Echo is a season-exclusive monster summon scroll. 
Use the Rift's Echo to summon a random boss monster, who, once defeated, will award you with a variety of Tuvala gear that will help you in your seasonal journey. 
Rift's Echo requires a full party to complete, so utilize server chat or the Find Party/Platoon function to find like-minded Adventurers to take the monsters down. 
Each party member may have a different number of Rift's Echoes on them, so you should discuss this within your party before proceeding with this content.

8. Use the appropriate Enhancement Chance to enhance your Tuvala gear.

Many Adventurers utilize the following Enhancement Chance stacks when enhancing to certain grades.
Your success rates may vary regardless of the recommended stacks.

9. Level up to obtain a PEN (V) Tuvala Earring and PEN (V) Tuvala Ring.

You can obtain these by progressing through the Season Pass and leveling up your season character. 
  
Reaching Lv. 58 will grant you a PEN (V) Tuvala Ring, and reaching Lv. 60 will grant you a PEN (V) Tuvala Earring, so we recommend that you only enhance one Tuvala Ring and Tuvala Earring to PEN (V) each.

10. Ancient Anvil. Guaranteed enhancement after failing.

Each time you fail enhancing an item, you will see "Agris Essence" start to fill up in the "Ancient Anvil" which, when activated, will grant 100% enhancement success rate for said item.

This is the amount of time your gear needs to fail in order to active the guaranteed enhancement success from the Agris Essence.
