Notes from author
This Build is based around extending the length of matches, pushing them beyond the length of what your opponent may prefer.
The equipment chosen for this build is both cosmetic and practicality. As it is INT based, enchanted and magic weapons are your best friend.
A magic composite bow +10, armed with moonlight arrows and poison arrows.
Velka's Rapier +5, gives you the melee prowess you require in close quarter situations.
The Grass Crest Shield, since it will be on your back anyway while you're using the bow.
Logan's Catalyst, since the build is based around lengthy matches you'll need all of your available casts, not quick two shot kills that the Tin crystallization catalyst can provide under the right circumstances.
As for how you should approach combat in my opinion, Keep distance, slow opponents will be fun as they can't keep pace with you. poison them, circle, shoot, and have fun. As for a opponent with the same speed, you may be forced into using the rapier, which isn't a issue as it's quite the deadly weapon. Lastly, when facing multiple opponents at once, you're already in a bad situation. but not one you can't win. Separating them is your best option, and also the one time i don't mind casting pursuers and going after them with rapier like a mad man once they split apart. Make those who once felt safe in numbers suffer once they're alone am I right? And if you can't separate them, do not threat. It's only a game, so roll BS like a Madman and get some hate mail. One of the few times I approve of such tactics.
