Feel free to suggest your own ideas on how to.
Poison:
- Increase chance to cast the poison effect on the target.
- Increase duration of poison by 2x.
- Increase the damage dealt by the poison. Maybe make it scale with grades ( G1= 5%, G5=20 % etc... ).
Stiff:
- Increase the duration of the petrification effect.
Why? Because it would add more choices in rarecrafting and more variety in legit combatstyles. Currently I find all of these rares either underpowered or even completely useless.
