Me and Kilz just did Foresight in EQ Test Server.. We had 18 toons. 12 toons died one by one and the event did not fail. When kilz's bard died.. then the event failed, Looks like minimum of 6 toons have to be alive during the event.
I dunno if its a huge change in the code of the event but it would be very nice to correct it cuz its hard to do this event with people that are not heavy geared...even with toons heavy geared we have 1 dead very often. Anyway, thx for it
