How would a str,Agi,luk build fair in Ragnarok?
Not very well. It's something that might work early on but it'll be incredibly slow later. NOT recommended.
Hi, I just made a swordman, I don't have any experience with killing classes, my other characters are caster, what skills should I get as a swordman?
As a swordsman
bash 10 (prereq for Bowling Bash)
increase hp 10
magnum break 10 (your only AoE until you get bowling bash)
2h mastery 10
provoke 5 (prereq for a peco)
endure 1 (prereq for a peco)
Stat wise as a swordie, it really depends on HOW you plan to kill things. If you have a friend that can tank stuff and you can afford to spend money on sp recovery items, then just dump your stats into str, dex and vit and spam Magnum break. Otherwise starting with a str, agi, dex build and then slowly ramping up your vit over time also works.
