So, i've been wondering if there are any guides or something like that for runestone keeper out
in the net.
Only thing i've found was the wiki :http://runestonekeeper.wikia.com/wiki/Runestone_Keeper_Wiki
which is okay, but misses a lot and is also not so good to browse for infos.
So, does anyone here know some links to guides or something like that?
Would be great.

I haven't found anything either. Some icons are ambiguous to me (e.g. the purple stuff that you spend in addition to gold at a store) or I just wanted to understand something better, but it seems that there is no help file. A real shame.

These are souls; you're not paying them to get them, you're using them to use items. Think of mana, but only for items. It's being explained in tutorials.

Thanks. I figured it out after I had posted, but still thank you. ;)

I'm having trouble with runes.... I don't quite understand how you get them or how to use them, and the forge system as well!

Sorry for the late reply. Runes are random drops from enemies, and can be either bronze, silver, or gold. Within the game, you will also sometimes come across a rune forge, which gives you the opportunity to upgrade 3x bronze to 1x silver, or 3x silver into 1x gold. Runes can be spent in-game at a couple of places: certain shrines let you "pay" with a rune for increased luck or other things; other shrines take rune payment in exchange for tattoos, which will bestow new abilities.

Finally, in the little town before you re-enter the dungeon, one of the buildings lets you form runewords that change the way you'll next play. Runewords can be unlocked with playthroughs. I can't remember how I got all of them unlocked. Some may have been unlocked by beating the dungeon with a certain character. Furthermore, a couple of characters can only be unlocked by playing with a runeword (i.e. specific game mode) in place.

I've just read your response, thanks for explaining this... now It's a lot more clearer!

No problem. Happy dungeoneering!
