To advance the space 100 yards it will require shifting 300 cy of rock


The wizard's got Move Earth (stone) at skill 19, ER 15 and FP 14 I think?

so in theory he can cast 12 cy move stone spell that will cost 23fp.

What if it's just a shell of stone (the bunker mentioned above)? The volume of stone will be less, and they can creep along at Move 1 for the whole 60 seconds of the spell's duration. 500 yards will take no more than 10 minutes.

A rectangular shell 4 yds long, 1yd wide and 2 yds tall will have a surface area of 24 sq yds. Hence, 6 inch thick walls will be 4 cubic yards- 8 FP to cast.
