zos shivros challenge

I'm having a tough time getting over 100 points in this misison. I'm hero/henching it, as I'm in a kurz guild and nobody wants lux points lol. Anyway, best I got so far was 81. I was told there was a glitch that made it easy to rack up high scores, but it doesn't work anymore. Some help. Any advice on how to get over 100? I can play any profession but ranger, and have heroes on every toon. I've been playing a nuker, with 2 minion bomber heroes, a nuker hero, 2 monk hench, earth hench, and nuker hench. With some variations. At some point after wave 2 or 3 I'll flag my heroes at the guy I'm supposed to protect and go out to try to kill the adepts, but it takes forever and I frequently get interrupted by new things spawning. Advice?

Tried asking Wiki?
