Got this discovery 2015-05-22 when hunting Oro's near Fearless Firebase. Short stats: Weapon type: Shortblade SIB: Yes Recommended level: 6 Durability: Above average Damage interval: 7.0 - 14.0 Range: 6.0m Update 26/6/2015: Finaly got around to test the eco. Calculation for all to see in case I did an error: First TT: 105.33PED. Added 888 sweat to increase value by 1 PEC in the TT. Real value: (10533)+(1-(888/1000)) = 105.3311 PED After one use: TT 105.29 PED. Added 237 sweat to increase 1 PEC. Real value: (10529)+(1-(237/1000)) Decay: 105.3311 - 105.2976 = 3.349 PEC Effective Damage = (14*0,75)*0,925 = 9.7125 Damage/PEC: 9,7125/3,349 = 2,900119 Sorry for the long wait and hope my math is correct. Will add the weapon to entropedia.info during the weekend. Not sure if I will put it up for sale or keep it.
