Man you people make the buggiest damn games I've ever seen (not counting cyberpunk lol). >.< A year after you lock this thread (https://discussions.ubisoft.com/topic/99380/resolved-unable-to-complete-trial-of-the-morrigan-in-connacht-post-here?lang=en-US) and pretend it's fixed or whatever, I just did (or tried) the Trial in Meath west of Kell's Abbey. Killed the four guys that spawned and stood there for 5 minutes with nothing happening and the thing never ending....
Unlike in the video on that thread though, it literally never ended. The greenish haze stayed on the screen. IT wasn't like in his vid where it looked like it ended but you could restart it it looked like (the thing had an icon over the big bowl). Like i said there were 4 enemies, i was expecting more but they never showed. I had hit one of these I found the other day, and that one worked fine, but there were also more then 4 enemies.... that one was just west of Annagh Doo. Also in this one it looked like i hit one of the four enemies, he fell, had an icon maybe to stomp him on the ground (happened fast idk), but then he was just dead (no icon prompt, nothing). Maybe he glitched it?
EDIT: Well I tried it again and it worked, and i saw a enemy i didn't see the first time. The Boar Druid had a boar with him... I've seen this happen before with those enemies, the boar runs off to god knows where and takes forever to come back and attack you. you should probably tweak their boars to stay close and attack more often or something, and not just in Trials....
