[The sacrifice quest rewards]

Greetings,

after completing the sacrifice quest I will get rewarded with ready-to-go Excalibur Umbra or I have to own Excalibur and it will transform to Umbra version ? although if it's the first pick does it comes with a warframe slot ? because I don't have any open slots .

Sorry may be dumb but I'm a beginner , thanks in advance .
