Guild Wars 2

The six piece bonus for perplexity runes will apply 5 stacks of confusion to the user of the runes if they are interrupted by a thief using basilisk venom.

Basi venom is considered a stun. So rune6 works when you interrupt someone with th venom.

You misunderstood him Logi, he is using Runes of Perplexity and is interrupted by a Thief not using Runes of Perplexity. The Runes register that Fox interrupted himself and apply the Confusion, for some reason.

Ah i c, misread it. Odd bug o.o
