Hi, sorry this is off topic, but can you please tell me if there’s a working mod for Eye of Reckoning AoE?
Welcome to the forum. 
No, because it doesn’t need one. Why would you think it did?
what do you mean by “Eye of Reckoning AoE”? i thought EoR already targets everything near you (aka AoE), maybe increased AoE scaling with level?
if so then i don’t think there’s any like that as that’s a very specific request. might be easier to do it yourself imo. (foreword: increasing the radius in the dbr file will not automatically scale the fx to be bigger, you’ll need to edit the fx (and the variant fxs) too)
