I also managed to maintain the energy level above half, roughly 80% of the time using [glyph of lesser energy] and [Glowstone], last time I use it was to vanquish Snake Dance at 10% morale boost, then had to quit at Dreadnought's Drift after too many death penalty

The team build up: this ele build on my character, livia as n/rt healer, gwen as me/n spoil victor, olias mm bomber, alesia, lina, stefan (whom i want to kill for aggroing everything in sight) and reyna.
[build=Knock'em Down;OgBCkMzDrYV0D7zc1oPsAZA]
THANKS FOR ALL THE FEED BACK! if you use this build, Please listen to advise given by players below, they are good, I am trying to get my earth 40/40 set now.
another version after more testing
[build=Konck'em Down Version 2; OgBCkMzjqoHuKcF95oPpIVA]
[build=Knock'em Down Version 3;OgBCkMzkqQP0qgrAuY0HpQqA]
easy to use, keep attunements up, wards up, then cast 1,2,3,4 (if no 5 just go 1,2,3,4 easy)
Earth Quake will konck'em down, follow by ash blast to blind them, if they are in the ward knock'em down again with stoning, then end it with aftershock at 105+72 pretty much very dead lol.
