Enchanter stun mechanics
 

Do enchanter stuns stack, or do they overwrite? My enchanter doesn't have an 8 second stun yet so I can't really test it.

Basically wondering if color fluxing something that just got hit with color skew is actually
detrimental since the flux will overwrite it, or if they stack and exist at the same time.

Or another way to look at it, in AE groups, if one chanter casts Skew, another Flux, and they land at the same time, are mobs stunned for 4 seconds or 8 seconds?

They stack - they dont have debuff icons. The highest stun would take effect if you hit with both at same time.

Yeah, they stack, easiest way to test it is on low level mobs when you have three AoE stun, you will be able to perma lock them whatever the combination :
Flux : 4sec > Shift : 6 sec > Skew : 8 sec > Flux : 4 sec > Shift : 6 sec

if Flux or Shift wouldn't stack with Skew, mobs would attack again when skew wears off which is not the case
