[Star Wars] How was Savage Opress able to be such effective warrior immediately after Mother Talzin's spell, without any training, and why weren't more people using such a spell to become more powerful?

He started killing Jedi immediately after the procedure.

The thing is, he's not really that great of a warrior - he's just really, really fucking strong now. Rather than defeating enemies through sheer skill, he simply overpowers them.

That spell was nightsister magick, a dark side trick that gave him a huge boost. Two reasons why it's not used that often - one, it's a Nightsister thing, not a generic ability, and most Force users can temporarily boost their strength as it is anyway. The second, is that it's a dark side thing - so "light side" traditions aren't going to use it.
