New PB for endless - made possible by SuperMagnetism + SuperHoming + Dividing + Ghost
Here’s the build:
And here’s the recording from 1149 onwards (that’s when Sisu got activated; have somehow missed a few rooms 
)
I reached level 25 (max) at room 1030 (IIRC) and I was able to get the following perks from Hidden Treasures :
- The 3rd Spread Shot
- Zap and Improved Zap (I suspect this was causing the lag)
- Flamethrower
- Death Poison
- Ninja
- Hoarder
- Move Speed Up
- Dodge
- Buckshot
- Big Attack Up x2
- Jetpack
- Death Fire
- Adrenaline
- Death Shrapnel
- Balloon
- Bullet Time
- Fire Shots
- Death Blast
As the Plasma had +50% Attack Speed I probably should’ve run with it; but I assumed that my Deluxe 80 Looper would be better than my Exalted 70 Plasma - however looking at the Damage Simulator numbers I think I’d have been better off with the plasma (I’d have lost a perk for Piercing and it would’ve benefited less from Focus Shots, the +170 attack from chests and Ice damage, but the better dps (inc Blast damage) would probably have compensated for it)
