With this patch, NPC combat is changing drastically for certain NPCs and will continue to change for the rest over time.
Recently we discovered that all NPCs in the real game had actual levels set for combat. This means each NPC had an attack, strength, defense, etc. level as well as having “bonuses” which translate to equipment bonuses in players. There are ways to obtain the levels and we have been making use of them to include the levels in our own NPC definitions. This means NPC combat will function the same way player vs player combat does as far as accuracy and hits go. Hopefully this will lead to more authentic combat experience on /v/scape.
