Condition Duration Sigils
Answer: I suppose so
Answer: No
The sigil of paralyzation is very cheap and is currently bugged so it gives an extra second of stun on a S/D thief’s stealth attack (from 2 seconds to 3 second) This is very good because it allows for an almost permanent stunlock.
However, rumor has it that the sigil will be fixed in the October 15th path. So i would not design a build around it.
Anything I post is just the opinion of a very vocal minority of 1.
