Warframe has been updated to Ver. 35.0.4. You can see the patch notes for this update below.
Changed the Grimoire’s Alt Fire projectile to prevent frequent crashing for our Nintendo Switch Users.
This is a temporary change until the Code fix can be shipped in our next Cert build.
This alt fire projectile no longer applies chaining electricity damage, which greatly reduces the overall damage output of this weapon. While this functionality has changed, the explosion still functions with Tome Mods. We understand that this is not an ideal situation, but due to the prevalence of the crashing, this temporary workaround was needed until the permanent fix comes in our next Cert build. Rest assured, we’ll be reverting this change once that build ships!
