I think there is a boost… it’s just that your normal chance of getting roots is just about f-all… so some smallish multiplier (for the boosted chance) applied to ef-all is still… well… near ef-all. I’ve been concentrating on 22-1 for a while (it’s at least non-trivial to play, so is vaguely stimulating… vaguely). I think I get roots on average once every 5 or so attempts now, if not worse. This is over 30-odd attempts so far. Niiiiice boooooost SG.
I expand on this concept in another thread - here
(Laughing at @havok333 statement).
There’s nothing to make you realise the chance of getting something is actually low like starting to look out for it.
