You can train up to 5 million SP free and then inject/sub up to 20 million.
Can pretty much use anything up to and including Battleships, but not T2 Battleship weapons (smaller weapons to T2 is fine).
No cloaks, only the alpha account logged in (not multiple alphas and no omega and an alpha at the same time).
The skills that can be trained don’t all go up to level 5 (capped at a lower level).
