Being reminded of the relative ugliness of Revamped Cygnus in a discussion of the similarly questionable aesthetics of Hayato in another thread, I'm considering getting started on my Knights. Beyond the superficiality of it all, now might be a good time given the 10% bonus at the start of levels and I have nothing to do during 2X.
I remember at one time there might have been a sliding scale of stacking Cygnus Blessing (the Link Skill) in which each additional link reduces the percentage of each individual link. However, rereading the description of the Link, I cannot be sure if it has been changed or if I am reading it wrong.
From Max at Orange Mushroom's Blog:
Cygnus Blessing: The awakened Empress’ blessing protects you from enemies’ attacks, increasing your resistance to states and elements by 5% (10% for level 2). If other Cygnus jobs exist within your account, you can stack this Link Skill up to 5 times. If linked, this skill’s effects will be reduced to 2% (5% for level 2). (Link Skill)
It no longer indicates that the skill will be reduced in efficacy, in fact, I think I got the idea originally from the last line, "reduced to 2%," but that's obviously like AB's description that as a Link Skill it is 2%/5%.
TL;DR: Will 5 Revamped Cygnus Link Skills stack to give 25% Status Resistance. Also, just for fun and not as important; could someone make five of the same CK?
