Basicly I would not think to much in classes

From what I understand what you are trying to build is an archer which is able to cast magical spells aswell and will be a glass cannon.

Archers really need dex+per, spellcasters need int+speed and for glass cannon you will need con equal to speed.

It is possible to make this working however due to all the things you need you probably will see the results around level 14+ and a focused mage or archer would probably be a lot better then a hybrid.

From my point of view it is horrible to try and combine a caster with an archer due to the insane amounts of stats you need. So if you are looking for a build that would resemble an arcane archer you might want to consider some things.

Do you want to put the emphasis on casting spells? If yes? Then please make a mage, higher level spells work best with higher ranks in those skills, however when making a mage ignore perception, it is just to useless for them. And most importantly staffs gave high int, is huge spelldamage boost etc while your bow will provide no use whatsoever whenever you're casting a spell.

Do you want to put the emphasis on ranged? If yes? Then please make an archer, archers require a decent amount of dex+per and combined with glass cannon also con+speed. It is fun to play, has great versatility and provides you with a class that actually benefits from having high perception. (Read on as I have recommend a link to get a general idea about the archer.)

If you try to make it a caster archer with glass cannon you will need to maintain 5 out of 6 stat attributes, it is just asking to much if you also want a character capable of excelling at something, by the time it will start working like you want it to you are deffo 14+ if not higher.

Most conflicting thing is that archer benefits hugely from Expert marksman rank 5 ===> then he can buy the quickdraw talent, -1ap per auto attack, making bow attacks 3ap and crossbow attacks 4ap. Expert Marksman abilities aren't that impressive, however they are highly versatile. Thing is that using auto attacks is a very high damage after Act 1. As a caster you want to make sure you have higher ranks in the schools of magic as an archer you will rush to grab expert marksman to 5.

For a pretty versatile archer build I would like to recommend:

However you asked for a working "wayfarer" build, so I will do my best.

Assuming we are at character creation and the goal is to make a spellcaster with a bow I would recommend the following:

Take: Dex 8, Int 7
Take: Geomancy 1, Scoundrel 1, Aerothurge 1, Hydrosophist 1, withcraft 1
Take: Walk in shadows(scoundrel), Summon spider(Geomancer), Teleport(Aerothurge)
Take: Lone wolf, know it all(caster style), Bully(archer style), Petpal(rp sytle also a bit more xp)

Man, sorry... I give up... anything that I want to do from her on out leads to the character being an archer with a ton a rank 1 spells.

basicly the spells you would want if you did take 8 int are:

Geomancy, Summon spider, bless, boulder bash(bully)

Scoundrel, Walk in shadows, Fast Track, ... self medicate(7), cloak and dagger(10)

Aerothutge, Teleportation, farseer, blitzbolt

Hydrosophist, Rain(Bliztbolt setup for increased % of stun), minor heal, Slow current(bully)

Witchcraft, Oath of desecration, ... ... (take what you want, other stuff requires melee range so contradicting the idea of the build or costs tons of AP)

Pyrokinetic, small fireball, wildfire, flare/summon fire ele or immune to freezing

Most of these spells range from level 1-4 so can all be picked up fairly easily and early, making your character versatile, however you probably want more ranks in fire so small fireball will become better, also more ranks in water to pick up strong regenerate and (piercing) ice shard.

All in all what you want/need and what you can get is fairly hard to achieve and deffo requires the use of the teller of secrets selling you her books as soon as level 4-5. Otherwise your stats/skillpoints will not be able to keep up even with lonewolf.

I assume it was atleast of some help, so goodluck with your build!

With kind regards,

Rashar.
