I was wondering how exactly your supposed to use Runes? Ive been researching it for a few days now and cant digure it out. The most ive seen on it is to just draw them on something they affect and sometimes draw more than one alongside eachother. If thats the case, then what runes go alongside eachother best in the Elder Futhark for different reasons? Also (I cant figure out the best wordingfor this so im using Isa as an example.) What are the more direct uses od individual runes? And how obvious are they? Like, would putting the rune of Ice (Isa, i think.) On something that needs to be frozen or cold, keep it frozen or cold, or possiby completely freeze it? If thats how it work,, then how do runes like Gebo or Jera directly work?
