Combat and herbicide xp
Combat xp shown is based on an average gotten on task. In the combat input you can choose to get Ranged xp or Defence xp or Ranged and defence xp, and likewise for magic and melee. If you select to not use a steel titan this will adjust your ranged xp gain accordingly but it will always assume that you use a cannon (except for monsters in the polypore dungeon where a cannon isn't useful).Are you searching for sites Runescape accounts selling?
The amount of xp gotten from the herbicide is typically based off of a sample of 1000+ kills- more for tasks that drop a lot of herbs (e.g. Spectres), less for tasks that rarely drop herbs (e.g. Wyvern).
