At the same time ammo efficiency is being nerfed. It is now capped at 75% so no more infinite ammo with the new riven splice. Anything previously that gave over 100% efficiency now is listed as infinite ammo. Ex. Pistoleer will no longer say %60 chance for +102% ammo efficiency, it will now say 60% chance for infinite ammo.
With these changes to Ammo Efficiency (and Riven Dispositions, see below), all players who log in after Thursday’s hotfix will receive the following:

1 Built Forma + 100,000 Kuva
Players who have installed a Riven Splicer in a Riven Mod prior to Thursday’s hotfix will also receive the following in a separate inbox as a thank you for being an early adopter:

1 Riven Splicer + 100,000 Kuva
