Magnus’s RPG empire on the portal.

Mentally: "What a bunch of crooks!"
What are stone spikes?
If I pay 40, will I only get access to level 2, or to levels 1 and 2?
Is it 40 silver for a spell, or for access to a level?

Stone spikes are: spikes that appear from the ground
Effect on levels:
[None]: damage=12+4*SP
[Basic]: damage=16+4*SP
[Advanced]: damage=20+4*SP
[Expert]: damage=24+4*SP
Price: 10
Paying 40 only gives you access to level 2. Knowledge is valuable, but if you're a dwarf, it's half price, said the dwarf.

Damn...Magnus, what should I do? I haven't been here in ages...

Well, you're at the city of mages, and you were sent to find out about its characteristics and garrison. Difficulty +2. Price - 200 copper, do you agree?

More details, please.

You came with a report, told everything, and went to the tavern. You haven't been seen since.
