If you don't want to fish at all and you're happy with 74 fishing, skip to the next step.
Getting 84 fishing will get you 60 agility which is a decent enough level since the seers course is actually pretty good one to
train on. 84 fishing also unlocks anglerfish and minnows for PVM.
94 fishing is 70 agility and 70 str. Gets you access to Poll course and by the time you get graceful you'll be around 80 agility.
Also means you can get defenders very quickly since you only need to get to 60 attack.
97 fishing is 72 agi and str. Stopping here is recommended if you're going to do some PVM but your goal is also maxing, the last
2m xp will come from karams/minnows/anglers for PVM.
99 fishing if you're rushing max.
