I will train to 60 divination, then go on and train the following:
Slayer! Currently 86, want to hit 90!
Fletching! Currently 85, want to hit 90!
Hopping back into slayer because I remembered how much I want to have 99 slayer one day. If I train enough, I could have it by the end of the year, which would be incredible for me! Sometime along that journey I would most likely achieve some combat 99's as well, serving as a great all around skill to train
