I've been all over Trampoli and haven't found a little crystal yet! I guess they're just that little "huh"? has anyone found them? and if so please tell me where, my eyes probably aren't what they used to be. please respond Thank You!
I've come to find out that those little crystals are not rare at all. It did seem like that before I got some though :). When I go up to the Towers now I hit all 5 and sometimes I get none but more often than not I get at least 2. I have actually gotten 3 from one Tower at one time. In the Tower treasure chests you get level 1, 2, 4 and 8 depending on which tower you're in.You always get the same level crystals in a given Tower. The Tower that takes water rune stones gives you level 8, the Towers that take rock or tree runes give you level 4. The Tower that takes grass gives level 2 and the one that you can use any type of rune stone gives level 1. I should also add that I have gotten a level 9 and a level 10 but those I got from breaking rocks in the Lava and Green Ruins. If that's more information than you wanted...sorry in advance.
Oops - I didn't specify that the lvl 9 little crystal- rocks right outside the boss chamber in the Lava Ruins (I break those rocks all the time when I go to water my crops down there so it took a lot of rock breaking)
In regards to "The Hammer" - it seems like I never got any high level ores (esp. platinum) or any little crsytals from rocks until I had that. One mistake I made was using my first lvl 1 little crystal to make the Rune Sword which you obviously can't upgrade with scrap metal. I learned to use low level crystals to make my tools that you can upgrade and my high level ones to make weapons which you can't. You'll also want lots of little crystals to make the lab items to increase Raguna's stats and the elemental type items. Of course what made getting little crystals so much easier to get was when I finally followed the Runey guide (that someone was so awesome to post here) so I have an endless supply of rune stones.
