Weakness system
The Weakness system introduces weaknesses to certain monsters. When hitting an npc with its weak damage type your accuracy is increased by 50%. This additional bonus doesn't affect experience gains but let's you kill opponents quicker.
Different kind of element attack style can be obtained through the use of crystals on various weapons such as Abyssal whips, Abyssal staff, bows and their dyed variants as well as the Elemental bow and the Elemental staff. Various other weapons have different damage type. It is good to keep in mind that using earth surge spell with an elemental staff (fire) will cancel out the spell damage type and use the staff source of element instead. For exemple, any spell can be used against dust devil to profit from the accuracy bonus as long as the staff used is imbued with a thunder crystal.
All Undead monsters are immune to rot and poison damage.
