I'm not so good at scitalking so I wont answer to first one.
Yes, it is quite rare to find wand of cloning/SoCM. You can get wishes from many sources (fountains, scrolls (atavus?), oil lamps) so it isn't actually that hard to find them.
After all, it's all about luck. It's possible that you won't find any, and it's possible that you find one on every tile (I think). Sometimes I find none, sometimes one or two, once I got 2 clonings, 3 mirrorings, 5 chargings and a SoCM.
Well, first thanks for answering.
It's true that you have more than one way of getting wishes, but it's still rare for me. What happens is that when ever I get a promising character I prefer to avoid fountains as their results can turn deadly, for example, teleporting from GC2 to GC7, which means you're dead. Also oil lamps can result deadly in early and mid-early games, as an angry genie is more likely to own you in a couple of hits (you never know when he'll be happy to be freed or angry) which makes a risky move to use them unless you're well protected by pets or strong enough to take a genie yourself.
Regarding sci talking, I belive it's really important (that's why I want to learn how to do it properly), as if you don't have high INT you won't be able to make good profit from the scrolls.
