Echoing Grimoire

The Core effect rewards repetition: casting the same skill again and again adds 5% damage each time, stacking five deep. It wants a rotation that leans on one skill rather than cycling the whole kit, and it takes a few casts before it is worth anything.

The Core effect pays nothing on the first cast and everything on the sixth, so a single number for it is misleading: what it is worth is a ramp, and the average over a chain of casts depends on how long the chain is.

1. 0% · 5% · 10% · 15% · 20% · 25%

   Damage bonus by cast, repeating one skill

   Casts 1 to 6: 5% a stack, 5 stacks at most, so the cap lands on cast 6. The 10 energy line adds a flat 15% from cast 4 onwards.

2. 10%

   Average bonus over a chain of 5 casts

   (0 + 5 + 10 + 15 + 20) ÷ 5.

3. 17.5%

   Average bonus over a chain of 10 casts

   The first 5 casts ramp and the remaining 5 sit at the 25% cap: 175 ÷ 10.

4. 30%

   Crit rate added once the chain reaches the cap

   The 15 energy line pays at max stacks, which is cast 6 of the chain onwards and stops the moment you cast something else.

The item says the bonus applies "when using the same skill consecutively" without saying whether the first cast of a chain already carries a stack. The ramp above starts the chain at zero, which is the cautious reading.

• Irisal and the Forsaken Held Item Pack

  The same 3 held items sit behind both: Irisal is the only Alpha listed as dropping the Echoing Grimoire, and the Forsaken Held Item Pack rolls one of the same 3 at a random rarity.

No in-game recommended build names it, so there is nobody to list. Its Base effect points it at DPS Aniimo.

The 3 most recommended held items sharing the Damage Amp Base effect with the Echoing Grimoire.

Item	Core effect	Builds
Ferocious Fang	Equipped Aniimo gain 0.7 additional ATK per level.	34
Explosive Gloves	Increases Damage Amp by 5% for every 10 EP currently available.	3
Fission Needles	Each basic attack has a 50% chance to deal double damage.	2

All 11 grant +10% Damage Amp at Legendary, so only the Core effect separates them. These are the 3 the in-game builds pick most often; the other 7 are on the hub.
