Guild Wars 2

I’ve been trying to get this achievement since the whole Queen’s Jubilee started. I battled numerous champions. I’ve met: Stony Shield – at least 5 times, Blazing Gun – 3 times, Whirling Edge around 6 times and Heavy Hammer 10 times in a row! Still haven’t met Lightning Blade. It’s supposed to be random so why did and still do meet Heavy Hammer 90% of the time? Say what you guys want but I think it’s a nasty bug considering new content starting in a few days :/

Welcome to the not so wonderful world of RNG based content.
I was running around with a friend doing these as well. He was lucky enough to get 5 types at 5 towers. These are also going to be around until September 3rd.

I’ve got the same problem! You can’t start a fight with Lightning Blade in one of the maps. Thinks that’s the problem.

If you can’t start a fight you might need to run to the tower first and talk to the npc to activate it.

The tower events which includes the fights with the champions have to be done in sequence. You talk to the balloon pilot to find out the current event in the chain and push the chain until it gets to the champion.
