V1.21 update : Fixed low tier bandits having too much damage resistance.
V1.2 update : Fixed resistances, stalkers with exo's, skats and armor of that tier can take much more damage before going down. Fixed expert ranked not using AP rounds. Plan to soon change artifact drops to include lead boxes.
V1.1 : Previously Rare NPC Loot, this addon adds rare item and artifact drops with increasing chances as NPC rank increases. It also increases NPC damage resistances as ranks increase. A novice stalker is going to take more damage than master stalker, so effectively higher ranked NPC's will be tougher to kill. This balances well because higher ranked stalkers will drop more rare items at higher chances. Another change included is that expert rank will use AP rounds in their rifles more often, and master and legend use only AP rounds. Expert through Legend ranks also carry high tier weaponry now capable of easily killing you in an upgraded exoskeleton, watch out!
Drop rates in previous version were too low, now they are balance better so you should see some good loot. This mod may need some more balancing, so please comment if you find something gamebreaking that needs changing or just have a suggestion. Look at PDF's included to preview loot chances.
