Hey Surek, what would you consider high corruption farming? 200? 300? 500? 900?
Do you want fully fleshed out build guides or just a hint into a direction that you can do?
I would throw out the top 3 of my builds (all of which have various levels of varations depending on preference.
Harvest Lich (2H Melee)
Lightning Bladedancer using Fulgurite Shard (Shuriken for DPS Lethal Mirage for Burst)
Erasing Strike VK (2H Melee or 1H Melee + Shield; 1H is HC viable)
All 3 of these are not top meta, but can handle 300 corruption with ease and 500-600 corruption with some dozens hours of investment. The Harvest one can go up to 1000
