Restores classic Pulverizing Auger's range, cd and damage while keeping new functionality.

A simple mod to restore Pulverizing Auger's old identity as a shorter range spell with higher damage. What this does:

[*] CD back to 6
[*] Range back to the old 3 to 7 scaling (8 fully invested with Archmage)
[*] Damage increased by a fair chunk (20, 230 scaling back to 30, 300)

What it keeps:

[*] Physical damage amp when digging a tile (6 turns)
[*] Same digging limits (scaling from 1 to 5)
[*] Can synergize with new beam class evolution
[*] Probably something I forgot
