i have a lvl 93 with 84 agil at ape atoll but with my hp i can take the hits...
i also have a lvl 3 skiller like you with 52 agil and tried wildy but you get hit waaay too often. the higher your agil, the less likey you will fail, so train it high then move on to something like barb course (maybe around 60s). use cakes because theyre low in weight. when you get to 85, gnome stronghold to 99 or if you wana spend $ on food use cakes and barb at around 90-95 when you're less likely to fail. gl
