Tips for Freifurt quest D?

[TradeGy]

Been trying for a little while with different strategies but either I get overrun by the buffed Wheels or the few times I make it to the last boss I can at most get it to half health before my castle is destroyed.

I made it within like 2 tries and without restart, but find quest E&F frustrating. I hate having my choices banned and I demand that damn mutator removed, for real.
Anyway here's my build, hope it helps:
Battle Axe;
Arcane Tower;
Heavy Armor;
Architect's Council;
Power Tower;
Loan

I built 2 gold mines at the first wave, and got the 2 Shrines (left & base doorstep) enabled at the first 2 waves. For unit choosing, 2x Fire Archers to take down siege units; 1x Berserker to slay Wheels; 1x Spears to counter fast units.
I heavily rely on Castle-Ballista towers buffed with Power Tower to deal tonnages of DPS. A Castle-Doubleshoot tower is the best choice for Flak-ing flying wizards at Wave 8. 2x Armored-Fire towers are decent to carry a stable frontline in the way of the boss.
Tech: 3x Ranged dmg; 3x player fast atk. Base upgrade: Buff player, then Holy Curse. Trust me, a Battle Axe with AoE plus max atk speed + Holy Curse shreds like everything.
And remember to make the temple at Lvl.3 to counter the boss. Overload towers, and my boss didn't even make it to the top of the first ramp.

I can't remember exactly how it went, but I believe I went with Bow for weapon, Auto-attack 33% cooldown, Ranged damage 25%, Castle health +150% (important), Warrior Training for +100% damage over time, and the last pick is 'free' I suppose. Could go daredevil, or heavy armor, or power tower. Shrines is good to set up in beginning, temple at level 3 for final boss is good. Use the summoning circles to boost your early income, can do 6 ogres at least with light micro (likely ways to get more depending on defences/setup). You can play with that. Try to keep your upgrades going, get to lvl 3 castle on wave 4 or 5.

I have 100% on everything up to this point, (wow 100 hours now...)hours in game, love it. But I have probably spent about 10 hours and about 20 methods on this. This has become not fun. I dont believe anyone got this one try, no restarts, complete ♥♥♥♥♥♥♥♥. I have given up. I have only given up once before and they had to nerf the level. I just cant anymore, its crazy how hard this is. Someone needs to have a detailed walkthrough bc i just dont get it

You're spending coins on upgrades every 4 rounds but still have enough to build your economy and defenses? I don't doubt you, but it's like hearing that all you need to dunk a basketball is to jump really high. And why are you prioritizing shrines in the middle of nowhere that can't even help unless you're already overwhelmed and your economy buildings have been destroyed? The only thing I really got from this is that the LVL 3 Curse upgrade does a lot of damage, which I never pick because it's a tower defense game and I want to upgrade my towers for cheap. You should consider making a walkthrough.
