Spell Disk 1.0j update

[list] [*] Adjusted the reroll Starting Spell Behaviour. Instead of looping through 50~60 spells, the rerolls will roll through the entire spell item library. [*] Increased the value of gems of gem spells. They count as "2" gems instead of 1 gem to address the issue of getting too weak in certain aspects after fixing a bug. [*] Adjusted the damages dealt by royal and imperial enemies that appear in Rampage Mode. [*] Fixed an issue where multiple Librarian Bag (possible by Emperor outfit) had multiplicative damage multipliers to each other instances of the artifact instead of additive damage multipliers. [*] Fixed an issue where multiple Dagger Locket artifacts had multiplicative damage multipliers to each other instances of the artifact. Adjusted the artifact's requirement a bit. [/list]
