Erile, the 32 spec requires a grand total of a Grade 6 manacost. Perfectly affordable at level 200.
Second, are you 16 or 64 combining your pure O amps? Ignore angering except very lightly at the beginning, and focus on just the manafarm first. You'll reach about 100k mana, while U-ing it(you'll make newgem later which will be optimized) then make slow traps G8 or so. Don't anger to 999 obviously now...
Anger at most to 100 monsters until wave 50. By then you should have a G15 or so..? Make a killgem using the 32 spec in the guide, its inefficient but the best with no black skilling. Replace with white, even, I'm not sure which is better at 0 skill. And start the higher angering(250 monster?) and killing. Utilize freeze to let your gem catch up if its chain is failing. Use curse for +50% damage dealt and -40% armor or something like that. It also increases slowing effect timer, so use it to help your farm too!
At wave 90 I'll guess you be close to G25-G30 maybe? Hopefully, anyway.
Then go all out, by now on killgem chain should be past 10 hopefully, again I'm not sure but it should be with a large black or white component.
You'll gain about 1-5 million xp I estimate, times your traits(suggest glaring, haste maxed, beacon storm maxed, and level 1 manalock...about beacon storm place ~10-15 walls by wave 3 around mana gem, problem solved, and beacons give added xp which you can leech from them at wave 50.)
I'm not too confident it'll work, but give it a try please it can't hurt.
OH almost forgot- skills!
Max mana leech
Max true colors
Max fusion
Max traps
About half in masonry
Max crit hit
Half in resonance if you can.
Lower if need be. Also, don't max-max them. Max them to the highest multiple of 3 of course. Leave enough for a trap, a few G1s, a G6, and an amp...for your level of fusion I'm estimating 4,000 mana or 4500?
