* **sc_failingsc_db.txt**, list of SCs that causing incoming SC failed to activated.
* **skill_sc_assoc_db.txt**, Skill-SC association (replaceing sc_set, add_sc, add_sc_with_vfx).
* **sc_script_db.txt**, list of additional script that given when specified SC is active.
* Removed '**berserk_cancels_buffs**', all cleared buffs when SC_BERSERK is activated now written on sc_endsc_db.txt
* Change default value for '**debuff_on_logout**' to 0 which by default only save statuses that doesn't have SCF_NO_SAVE
