Excalibur/Prime

"A perfect balance of mobility and offense, EXCALIBUR is the ideal Warframe for new players."

- In-game Description

Excalibur Prime is a Primed Excalibur, featuring an additional  polarity slot, a higher shield recharge, as well as a  Aura slot, rather than a slot without a polarity, but otherwise identical. Excalibur Prime is a founders-exclusive Warframe.

Please note that concerning mastery rank, Excalibur and its Prime version are considered separate for unlocking mastery levels. That is to say, each has its own 6000 mastery point contribution for reaching level 30.

Acquisition
The Excalibur Prime Warframe is only obtainable through upgrading your account to Founders status of Hunter or greater. It comes with its own warframe slot and already augmented with an Orokin Reactor.

Founders' program is closing on the 1st of November as announced on the warframe forums. This closure is inclusive of pack upgrades.
