I got, like, 7 in a single playthrough and I still haven't used 5 of them sparing them for better times.
At little less than 400 golds a pop they don't exactly come as cheap and convenient to abuse without a single worry.
I'm also NOT planning to use them on fighters and so on (which reached STR 20 anyway over time) when the time comes, but on characters like Shadowheart, who could really benefit from a temporary boost in martial prowess.
