Hire an ally of one of the top 50 overall and then unload your spies on them. The more allies you hire the more chances you have to get the equipment. I believe this increases your chances, good luck.
Bwa ha ha, trolls! First - be big enough to hit T8. Then. Have 6 xtals and all the pots for the item phases. Then. Skim unload the entire eb (2x atk, 3x ass or 1-2x stl or 3-4x scout ... every 5 minutes from full bar). Burn xtals only when you can unload both bars. Then skim some more. Get in for the item phases. Even if you don't get the item, your hit plunder will be sick and insane. Yeah, your end bonus will still suck, but let's face it. Nobody does T8 for the end bonus.
You guys got it all wrong! You scout bomb the owner of the clan in first 10 min before EB then you put on a spiky helmet. The helmet gives a drop effect and hitting the owner makes the EB think your really strong. Then get in all item phases and use full pots mith and skim troops till you use an xstal.
