I just did it.... what, 10 minutes ago on my rogue. We got up to shade but we had a little trouble downing him, people were moving when they're not supposed to etc, and after that I thought to myself "Hmm, I wonder if chess is still soloable?" Well, it is.
What you'll need:
A raid saved up to Shade/Netherspite and obviously they can't have done the chess event yet. If you've not cleared shade, then you'll have to do this straight after the raid, as stealth detecting elites spawn. As soon as the raid ends, if you have a stupid leader, they'll leave first, and everyone else will leave making you leader. Now, stealth your way down to the chess event, and talk to the king of your own faction.
Now believe it or not, this is the hard part.
Control your king, and hit the armor buff. Dispel the control buff, then take control of infantry, and move as many as possible forward, then get the two horses out in proportional positions. Take down the opposing faction's mage, then set your king on their king. While he's autoattacking, switch to the mage and spam raining fire. If they're low on health, switch to the bishop and heal. It took me a few tries, but I eventually did it, and the rogue belt dropped, and the cloth helmet dropped PLUS a bonus of 2 heroic tokens. Now, this group in my guild isn't going to Kara for the rest of the week, so free epic belt for me, and they won't find out, unless you tell them OFC.
Now, some of you may dismiss this as common sense, but I know many people who don't know of this trick. Just make sure that unless you want to get kicked from your guild, you do it towards the end of the week. Even if they do get up to chess event, how do they know it was you who took the loot? :devildance:
If you have trouble doing the event on your own, get another stealth class in, I'm sure they'd be happy to help you for free epics.
Also, it IS still possible to stealth through from the back entrance, just very, VERY hard. You have to make good use of distract, line of sight and vanish.
Anyway, good luck, and don't blame me if you get kicked from your guild! :wave:
