Progression gives a slowly increasing elemental attack bonus that is valuable when running two Omega summons in longer fights.

These weapons offer a Big Omega Attack alongside an uncommon Progression skill.

Garnet Broadaxe, Aquamarine Hatchet, Zircon Edge, Peridot Crossbow.

Even without serious aspirations, it will help getting more Honor milestone rewards. For new players, this will help with time and AP/EP efficiency during events.

Flohrenberk provides a 10% bonus to all Honor points gained during events (excluding this event and Unite and Fight).

They are in high-demand for things such as uncapping characters, Revenant Weapons, and Class Champion Weapons, so buy the first set of merits at least.

Champion Merits are used more often than Supreme Merits.

However, your pendants are more cost-effective on other items. Buy these if you need to uncap SSR characters or if you need more for your Revenant Weapon.

Supreme Merits drop quite often in higher-end content.

Seal pendant prices reset every iteration, so buying at least one or two of each seal can be cost-effective.

You can also trade 1 of each seal for a Golden Beast Seal to host Qilin or Huanglong raids (see below).

Note that raising a weapon to Level 150 requires a tremendous amount of fodder, so it's often more efficient to stop after unlocking weapon's skill upgrade (usually at 101 or 120) if fodder becomes scarce Buy the respective elemental seal(s) for the weapon(s) that you bought if you can afford it.

Seals are used to uncap Celestial weapons to 4★.

Zhuque Seal, Xuanwu Seal, Baihu Seal, Qinglong Seal.

Even if you have all ten Eternals, materials such as Antique Cloth are always in in demand.

The Eternals Unlock Treasure Set provides an excellent amount of resources for minimal cost, significantly cutting or eliminating the materials grind to unlock an Eternal.

Note that while stockpiling recovery items may seem unnecessary at low ranks due to the frequent AP/EP resets, it is helpful later when farming time-limited events for powerful rewards.

The investment for these is trivial and more or less pays for itself.
