Skill ring Quick breakdown of all rings, and a level guide.

[Anduril]

The lack of formatting was bothering me. I tried to clean it up a bit, and add a bit of extra info. [I'm super unclear on the Katana Gear ring (since I've not used it or seen anyone use it), so I'm not sure if my description is quite right]

[TaigaUC]

You haven't updated your sig yet for your latest guides though?

I'm basically out of space on the sig. It's a pain trying to fit everything in there.

[Strobo_Lemon]

I'm basically out of space on the sig. It's a pain trying to fit everything in there.

Maybe you can abbreviate them, like PD, DF, MB/TD 1, 2, 3, FP, SP, SU ...

Then again, it wouldn't work since the newbies wouldn't understand what the meaning of those abbreviations are.

[TaigaUC]

Yeah. Exactly.

I'm thinking maybe I should just make a post linking to my guides, and then link to only that post.

[Triple_S]

Yeah. Exactly.

I'm thinking maybe I should just make a post linking to my guides, and then link to only that post.

I was gonna suggest this, actually. A lot of your guides are quite helpful, and I've referenced them (or outright linked then) while helping some friends get into the game. Having an easy way to access all of them that isn't hunting your SIG down would be awesome.

On the knuckle chase ring. Will the gap closing affect increase as i lvi it?

Any ring that uses Lambda Grinders to buy does not gain any additional skill benefits, only small boosts to stats.

[Achelousaurus]

Great info.

Does L / Katana Gear Guard R burn through gear faster than if you activate gear by a regular counter?

[Anduril]

Great info.

Does L / Katana Gear Guard R burn through gear faster than if you activate gear by a regular counter?

Yes, there is a video that shows the difference on niconico.

A burning question I have with the JG PA rings, does it have to be used with their respective weapons to trigger the PA on JG, or can katanas or FI weapons be usable on JG?
