It's not just from taking lots of Eclipse after completing the quest for the Third Eye. I've tried taking a bunch with the shirt of the hacking gift equipped, and I tried it while heavily injured, since the skill itself seems to activate in that scenario. Nothing so far. I also already know Third Eye Technique.
Hmm, weird. I did not have the shirt of the hacking on (but was in inventory). Had Third Eye Texhnique. I took soaked eclipse, no + duration modifiers.
It looks like taking any Eclipse at all is enough to get the skill, once you've unlocked the ability to do so. I got it from taking a single pill with +1 duration, for just 6 duration of Ocean Sight.
Effects that don't seem to interact with this:
Also, it occurs to me that maybe the Writhing Flesh result varies based on your highest base stat. Strength is a fair bit higher than my next highest one, so I may not be able to check in the near future.
With Writhing Flesh (20) active, I did not get any special messages when taking Eclipse. Perception as highest stat.
1 Eclipse = 13 duration
1 Liquified Eclipse = 65 duration
I'm not getting anything with Reflexes as my highest stat, either.
Edit: I did manage to get a result for Reflexes, but only after I tried taking Eclipse while I was injured. Only one data point so far, but maybe that's it?
Hm, still not getting it. Tried:
- Full / low / no health, with bone stuff
- Full / low / no health, without bone stuff
- With no eclipse duration, with a lot of Eclipse Duration,
- Full ratty suit
- Gaining more / less turns of Eclipse than turns I had of writhing flesh
Nothing. :/
Managed to get Will as my highest stat (both base and buffed), and don't seem to be getting a Writhing Flesh result for that, either.
