I went in with dual anubis + shit on my loki team and made it to round 9 before failing to get a 10x and being 1shot by the angel. Probably doable if I didn't have such shitty colored subs ( I only had 9k hp total, but figured it was worth a try ;p )
Next try was mono red on adk team ( shiva/ares ). I died on demons due to shitty luck ( my combo brought down a row of 6 fire orbs twice and burned both demons down so much I got a double multi attack ). Think this one can probably win though.
On ama account I just went with the parv/artemis team I used for all the rest of them - swapped out green ninja for bastet for a few more hp. Cleared it three times with no issues, final dragon is much less stressful than the light one was - his nuke only does 17k ish instead of 24k, so it's nowhere near the madness. ( I quit farming light dragon when the first 12 feeds got 1 skillup in 2x skillup event, but I had failed 3-4x by that point and was a bit frustrated ).
For levelling up, I actually became pissed at plant farming so am ignoring pendgras for now, I just feed them and little dragons unevolved. I pretty much stick to king dragons, moltras and evolved dropped pengdras for anything above level 50, but lower level stuff I just feed anything I pick up. I've been farming weekend master for exp so have an assload of cash.
