I need to learn sep..

I equate it to bossing.

Anyone can boss, but to flick and do all that other shit is what makes a player beat floor 5. Just don't bail on floor 5 when time runs out - the xp is the end of the floor.

While I'm training agility i usually just watch a show and do farm runs every 80 mins to get a small break from it but those Mark of Grace defiantly do help since it feels like your working toward something else.

Agility on rooftops, especially at Seers, is hella afk.

As people here have said before, pop on some of your favorite chinese cartoons or teenage vampire drama on the side and you're good to go.

Its easy.
Purchase fg and hire Donahey or Tankist.

You don't. Look at as a prime example

High alch too? Idk agility sucks
