Skill enhance efficiently to conserve fodder
Grails and SR weapons bearing a skill can be enhanced to raise their skill level before being used as fodder, greatly boosting the skill XP they provide. Since each enhancement can grant a maximum of one skill level, and each fodder type has a target skill level that optimizes skill XP per Rs spent, there’s an optimal combination of fodder to use at each skill level for each rarity of target weapon. Use the tables I’ve provided in my Weapon skill enhancement calculator as a guide, or use the calculator to generate your own strategy based on the fodder available to you.
