I have to work on my staff skill first? What is rf staff mastery
rF (or r-anything) is the rank of a skill.
so rF is Rank F. rA is Rank A. The ranks are pretty obvious when you look at your current skills.
So buying the Staff Mastery (and subsequently reading said book) will grant you the default rF (Rank F) staff mastery.
Staff Mastery has 2 effects:
- Decreases the weight of equipped staves.
- Allows you to equip higher level staves.
So later (better) staves require a higher level of the skill to use, and it also decreases the weight of those staves (which is pretty significant, considering how low of a weight cap us Evies have) allowing you to eventually equip leather armor without becoming overweight.
Also, FYI, Staff Mastery can be leveled to r6 (although it requires to be level 48 to level it up to there, so we really only have access to r7; at least until the next update).
