Yes, the second weapon shown is technically impossible. I initially thought of the Ruby Mace recipe, but with 100 armslore a ruby mace would be only 45DI. And, of course, this is not a diamond mace (base) type weapon anyway.
Good find.
Edit, actually both weapons are impossible, because the first one with SC no neg takes two props to achieve (SC-1 and FC1 to counteract, resulting in SCnoNeg)
So, the first is actually:
1) SC-1
2) FC1
3) 50 FireBall
4) 50 HLD
5) 87 HLL
6) 50DI (not a free prop)
Mob drops are max 5 props including DI.
