HELP ME WITH MY SP FARMER AND WHAT MASTERIES

[Aznone]

ok so far im a pure in lvl 18 farmer i am not the richest person but i can support myself with some sos items. i have i think lvl 10 or 12 bow mastery (bow user for now, i have up to the white hawk) and lvl 10 spear/glavie mastery (hp buff it helped me alot at lvl 17) and i have around 2.5k saved up. i also have lvl 10 ice mastery i think and lvl 8 heal mastery. i am thinking of by lvl 24 to get atleast lvl 17 bow mastery. lvl 20 heal lvl 20 ice with all skills and mostlikely going to up lightning for the nuke later on and grasswalk and int buffs. i do alot of damage and can 2 hit archers (100 sp xp every one) so should i lvl up lightning more or heal or bow. im leaning more toward heal for therapy and lightning for the buffs but i dont think i need bow that much cus im an int user i was thinking keeping bow like 5 lvl below for the whole time and others maybe 3 below or more if i want to farm. i think i will stick with bow but i still have a chance to change.
