Weakness system
The Weakness system introduces weaknesses to certain monsters. When hitting an npc with its weak damage type your damage is increased up to 20% depending which weakness type a monster has. Accuracy however remains the same. This additional bonus doesn't affect experience gains but let's you kill opponents quicker. Currently, only the following monsters are considered in the Weakness system:
*Silver damage is dealt by blisterwood weapons, which cause a standard 20% damage and accuracy boost when hitting monsters with silver weakness.**Vyrewatches and monsters in the Vampire catacombs can only have one weakness damage type and spell type takes priority.| Monster | Weakness | weak |
