Firebolt rune issues (Gothic 2)

Try insert fireball in the console you can get it.

Here are the codes: 1) - for a scroll 2) - for the

Fire Arrow rune
1) ItSc_Firebolt code
2) ItRu_Firebolt code

I figured out the arrow ...
New problem!
After teleportation to a new area, the magicians endlessly try to tell me, be careful, do not poke your nose into the swamp, etc. (They did not think that I could already be sufficiently pumped).
As you probably all know, you need to get the bandit's armor from the pirates ...
Well, I didn't ... I
went to the swamp and began to blame everyone.
Yes, the bandits are strong, but one-on-one I’ll get anybody there.
I'm making my way deeper - I met Lucia - I killed ...
Then Torus - I killed ... (By the way, I soaked this Torus in the first Gothic, when the old camp got stale) I was
tired of fighting further
And besides, everything indicates that I should not was to blame them all
Hence the question:
Is it possible to advance in the game - do they complete the main quest - find a crow - dunk it, if you leave everything as it is or you need to "start over" (I have a save where I have not done anything yet)

You can find a crow ... but you ruined yourself with this a bunch of interesting quests.

I went to the swamp and began to blame everyone.

Fail without completing anything from the key plot?
And actually for what?
You will have time to fill them up at any time when you complete ALL their quests.
As a result, more exp and all completed quests.

the same troubleshooter with a scroll, I don't want to use marvin, where is this scroll?

problem with gothic 2 return I am going through the test by fire I did everything but I need to create a rune of a fire arrow I have everything but I only have to find a scroll of a fire arrow but I have been everywhere with the merchants and the magicians do not have found I don’t need codes I don’t know how to use and I do not have them, so I want you to tell me in which cave or place or in the chest I should look for the scroll.

quad-damage

And they often have these scrolls in the Yarkandar of fiery gloomies.
For example, in the swamp near the entrance to the caves leading to the canyon there is a cave there is such a gloom and he has two scrolls, fire rain and a fire arrow.
There are also such scrolls in Khorinis, but I won't say where exactly, I don't remember, but there is definitely more than one.

P.S.
Although if a novice to get into Yarkendar with the help of a bug with a fire, then you can just find a rune ready to find a "fiery arrow", it also lies on a swamp next to a cross with a treasure.
If I remember correctly, then from the camp of the water magicians you go down to the swamp and to the right along the wall you walk past the cave with the gloom and then there will be a cross on the ground.

You can take a rune from any Seeker, only you need to kill him in a special way. First, with an ice wave, then while he seems to be stuck in the ice, you kill as quickly as possible (before the ice crawls, you grow, and you need to search as long as the Seeker is in the ice! this is important, otherwise it disappears from the inventory)
