I am sure this exists somewhere else already. I don't like using those calculators because I don't like having to enter in data every time I want to see a result. I personally like all results in one place. I threw this together and figured if someone wants to sue it, they can. If the item you are looking increase (Base Item) is legendary, find the value of the base item, and go across to the item you want to infuse in to it. Results will be purple numbers. If it's Exotic start on the top, find the level of the item, and go down to the level of the item you wish to infuse in to it. Exotic results will be in black font. I threw some colors on the columns and rows to make it a little easier on the eye to track. Hope this is helpful for others like myself. Edit 1 I have come to realize Bungie does a sort of gift of infusion rate for smaller gaps. I have adjusted the chart accordingly. Everything looks to sync up now. If you find anything not correct, please let me know in comments and I will further investigate. Excel Formulas for anyone that cares Legendary: =IF((Inf-Base)<7,Inf,ROUND((Inf-Base)*0.8,0)+Base) Exotic: =IF((Inf-Base)<5,Inf,ROUND((Inf-Base)*0.7,0)+Base) Regards.
