Comparison to another set:
Deadly Virulisk Set:
-Normal + Piercing Defense
-Poison Defense
-Health Bonus +10
-Damage Bonus vs. Slime: Very High
Skolver Set:
-Normal + Piercing Defense
-Freeze Defense
-Health Bonus +10
-Sword Damage Bonus: Very High
So let's look at a simple example:
You go to the Royal Jelly Palace, with only a sword. What would you choose? The Deadly Virulisk Set or the Skolver set?
When I got the system right, both of these sets will be exactly the same, in the example above, cause they both got a damage bonus of very high in this example, and there is neither Freeze, nor is there Poison, so is there any difference? Or is there any set, which is even better in this situation? And if I play the Royal Jelly Palace not only with a sword, but also with another weapon in the second place, the Deadly Virulisk Set should be better, but is it really?
Deadly virulisk used to be good with the damage bonus that applied to all your weapons. But it would only be good for rjp, lichen lairs, and jelly themed clockworks. Which isn't all that much. A skolver set will benefit your swords much more than virulisk over the entire game. Which means, if you were to craft virulisk for the sole purpose of running rjp, you would still need other armour to get damage bonus against other families.
Which means you'll craft twice the armour to benefit your weapons. It's really just better to go skolver and be strong in other situations than just rjp.
