Whispers in The Wall, the latestWarframeupdate 35, has introduced a new secondary weapon called the Grimoire. The Grimoire is a spellbook that hurls a lightning projectile at enemies and is available for free. To obtain this arsenal weapon, simply complete theWhispers in the Wall quest.
Unfortunately, the Grimoire is a complicated weapon since it uses the new Tome mod system thatbuffs aWarframe’sability stats. It also falls short in damage range, making it impossible to use when clearing hordes of enemies. Players who want to maximize the Grimoire’s potential must understand its best build, mode interactions, and loadout assistance. Here’s a guide on the most broken Grimoire build to further push the weapon’s limits.

Best Grimoire Build and Tome Mod Interactions
Tome mods are utility effects that buff various player stats, including Energy regeneration, Efficiency, and Ability Strength. The Tome mods are categorized into Canticle and Invocation, and players can only use one of each at a time. For example, you can equip the Grimoire with a Fass Canticle and a Vome Invocation to improve how it functions.
There are 8 Tome mods players can equip inWarframe’supdate 35, each providing unique effects. The best Tome mod interactions for the Grimoire are the Xata Invocation, which gives you enough energy, and the Jahu Canticle, which reduces the Armor and Shields of other enemies within the Affinity Range by 5%. Some players equip old tome modes like Lethal Momentum, which beats the new Tomes in damage range.

Note that Tome mods are the heart of this build, and without them, the Grimoire is as good as useless. This is because the Grimoire has a low fire rate and functions more as a utility weapon than a functional tool that deals exceptional damage to enemies. The Tome mods are a great way to enhance the weapon’s utility, so acquiring most, if not all, of them is essential.
Grimoire Build Usage
Grimoire hasan alt-fire modthat slowly accumulates energy when players use the weapon. Once the alt-fire meter is fully charged, players should hold fire to hurl a plasma orb that shocks nearby enemies. Keep in mind its fire rate is low, and the projectile is slow. If you don’t want to use the Grimoire build to eliminate enemies, you can switch back to your primary weapon and enjoy the buffed effects with something that can annihilate opponents.
