Changelog 2025-03-08: (broken update? Check a previous version)

• "Food, Speed Potions & other items" field is now more compact.
• Fixed Cold Heart + Rogue's Treasure combo increasing more ASPD than it should.
• Fixed Ulle's Cap + Odin's Blessing combo description: [Base DEX >= 70] All skills' SP cost -20% --> -10%
