people did that as early as 61, because there are too many points on 5th arcane to level up once, and you can't start 5th arcane before you are level 60. So 61 is absolute minimum.
I love the last level!! It is pretty much the only level I play now because I continually try to outdo my high score
Personally I have my skills all completely maxed out and I manafarm with several grade 8 red/orange gems in traps at first and then once I'm comfortable I start covering the whole ground with traps full of level 11 Prismatic gems with red/orange producing at least 5 monsters per attack and 5 mana per hit
I recommend you try this, it's **** fun but the game lags really badly once you start to seriously anger your monsters. The main aim is to try and send grade 6 gems to all monsters for anger and get the armor to just below 200 when you start laying down heaps of prismatic trapped gems. For giant monsters though you need to push the boundaries a bit and make their armor just shy of 500 or their hit points somewhere close to but not over 1 million.
Just set up the game asap with prismatic gems, anger the hell out of your creeps and then go do something else for a couple of hours while the game goes through about 8 waves of creeps then repeat, eventually you will find yourself losing more mana than you gain but that is at around level 100+, this is when you should finish the map for your super high score
You should definitely try defeating the entirety of 228 waves of the final level, it's possible. Note that you don't need prismatic mana farm, you will do with plain red/orange, it will even provide more mana per second. The main concern that you should be worried about is fire power, in order to defeat last waves you will need a gem that does at least 1 million damage tops, and a set of red/cyan traps. You will have to supergem massively, so be prepared And when you will get a gem that does 10k tops, your 1M HP monsters will not last more than 2 laps.
Yes, you won't have time to "go do something else for a couple of hours", actually you will do a mana pool every minute with all the lag, which might be about 5-6 frames within the game. Also try to click ahead of the game, sometimes it provides an effect of you being free to combine gems while the rest of the game is pretty much stalled.
well, it did take more than 2 days IIRC, people are planning to get 10b EXP off that level, and they estimate the time needed in more than a week. Yep, this level of gemcrafting is not for casuals.
I beat it right after the last arcane guardian at level 6x. Dual Gem Mastery helped a lot. I created 2 dual t4 gems in the very start and pushed my r/o gem to 222 speed. After that I set up ~15 traps with t1 orange gems and a t6 blue in front of them. Pushing my Mana to about 30k I created my 6 t7 dual gems and threw my bombs. notice this was done w/o splash mastery and angering monsters. i finished with a score of about 25k.
Afterwards - when I found out that angering monsters hugely increases score I came back to beat ~level200 with level ~100 and splash and prisma mastery. In the end I had called all 228 waves had set up traps and towers on each free space with r/o t7, r/b in every 5th trap and some prisma t11-12-13-14 gems next to each other and t11 prismas in every tower. This was when I got sick waiting for 1100 monsters to get down with 1kill/minute so I bombed tha middle. This way I reached about 200k Score.
I came back later with better skills and reached 300k in the first 100 waves after I got sick when the lag began again
But after all next GC will be out tomorrow so I'll be playing that.
