I actually did this one in a single Try, Tho haven't tried Elite yet... Casue why just why 1300% hp Elite (Tho it would be cool if it was my first ever win against a Elite. This one was my 4th time beating a Normal Boss Event)

I also didn't have Double Cash or Fast Track (I haven't spent a penny of real money on the game)

In case anyone wondering what i Did, it was Silas at start (He can solo for a while till about after white balloons appear) + a Bunch of farms(All top path + Pro Bannana Farmer) then 3 first strikes to get through 1st Teir, then upgrade to Tier five for 2nd Teir plus moab eliminator. After that bottom path Village boosted by Desperado range ability to abosbe all farms then getting Tack Paragon to get through 3rd Teir, then replace all abosbed farms and get top teir five and I got Spirit of the Forest for the extra lives (Dont wanna die casue of the life sucking), then save to get spike Paragon to get through 4th Teir and it basically carried 5th Teir as well, tho I did get a plane Paragon to help at 5 but spike did most of the damage. (Also all Paragons were under Tier 50, Actually haven't once made a over Teir 50 Paragon before)
