does anyone save level up points to get silver ones at a later level, or do you just blow em as you get em in bronze?

Doesn`t matter if you save em or blow em as it all ends up being the same number of talents when you decide to allocate them all .

Personally i spend them as they become available .

Your level-up points are specific to the level you just gained. You can't get a silver talent for reaching a low level by spending it later; the talents you get for the lower levels will always be bronze, no matter when you spend them.

Nowadays I spend talents as I get them, but the first couple of times I played the game, I kept one talent in reserve, in case I needed something I didn't know about.

I keep a stack of bronze talents saved up at the end of Chapter 1 so I can level up my silver sword styles as soon as they become available. It makes the fight in the sewer a LOT easier. Other than that, I don't bother saving them.
