Early Game Character Building
This guide gives general character building advice for the early game. Early game generally ends when you've reached the latest Ecumenical Temple spawn level, Dungeon level 7.

Build a Basic Plan
Beginning
At the very start, focus on your primary killing skills. It's better to end combat a round early than being able to survive a round; the former means your enemy is dead. Also, melee accuracy and magic success rates are important to raise. You don't want to miss 5 times in a row, just for your enemy to get 5 more hits off you.
For melee characters, this involves raising your weapon skill until it can kills your foes at a 'comfortable' rate. How much is comfortable? Your ulimate goal is to hit a weapon's minimum delay; where no more training can increase your swing speed. You can view this by selecting the weapon in the i'nventory. While it certainly is possible to only train one skill until you hit mindelay, it is probably not desirable. Instead, weapon users will want to train up to (mindelay skill - 6): the skill required to consistently hit enemies at 1.0 aut (barring the shield penalty).
For magic based characters, this is getting the useful spells in your starting book to acceptably low (at least less than 10%) failure rates by training their respective spell schools. Depending on your class, it may require training towards a level 3 (such as Frozen Ramparts) or level 4 spell (like Flame Wave). More details below.
Defences
The most straightforward step after training offense, is to train your defenses. You'll want to reach 'comfortable' numbers in that field. But if your offense starts to become lacking again, start training that again. If you aren't into micromanagment, you can just train both at the same time.
First comes your HP. For any character, Fighting skill is a must. Not only is the bonus to physical combat is useful, but the extra HP is precious, especially to squishier caster types. After all, you don't want your Felid to get 1-shot by an orc priest's smiting.
For robe or leather wearers, this is likely going to be Dodging (which contributes to EV), and for heavy armor wearers this is likely going to be Armour (which improves your AC proportional to your armour's base AC).
Shields provide an EV-like boost to your defenses, allowing you a chance to block some incoming attacks. Especially for species with body armour issues like Trolls and Octopodes, shields will prove useful. For as long as you can still attack at a sane delay or cast your spells at a reasonable rate, you should be fine on the skill.
A note on hybrids
Even if you are aiming to be a "hybrid", don't try training both your magic and your melee at the same time. You will have two ineffective killing methods, and they won't benefit you simultaneously.
Auxiliary Skills
During the very early game, skills like Evocations won't be the most useful. However, a strong wand, like a wand of paralysis, is often worth investing into, even in said early game. Five (5) Evocations are enough. Investing in these skills should happen once you get your main offensive skill up and running.
Don't worry about Invocations. Most gods have 1* abilities that don't require much training to be reliably invoked. And of the zealots, only the Abyssal Knight can actually make use of the skill. You can start training later; while powerful, Banishment can't possibly be your main offensive too.
Stealth may be useful for species with extremely high aptiude. Think Felids, Vine Stalkers, and Spriggans. All three of those species, thanks to their low HP, will want some skill (~5-8) to avoid troublesome ranged foes.
Stats
Your character gets an allocatable stat point every 6 levels. Where you put these in the early game depends on your character and perhaps, your plan for their future. Stat zero is a valid concern for some starting character combinations... though, don't worry about it yet.
Strength
Strength increases physical damage. What else do you need? It also alleviates some of the penalties of wearing armour. A strong choice for any physical attacker, especially those who (will) wear heavy armour.
Intelligence
Intelligence improves your spellcasting rates and spellpower. Spellcasters should almost always use their stat points to get more intelligence.
Dexterity
Dexterity improves a variety of defensive stats, like dodging, shields, and stealth. For stabbers in particular, it'll improve your chances of landing a "stab" while unseen/unnoticed.
Gods
Some backgrounds begin worshiping a god, but characters without gods should consider which god to initially worship. Read the section on Choosing a god for more information.
Skills by background
In the early game, preferred skills are directly based on the character's background, with a few variations due to race.
Review the Skills page if you are not sure how to turn skills on or off. Life gets much easier for characters who focus on just a few skills while getting started.
Warriors
Whether ranged or hand to hand, Warriors kill by using weapons or unarmed combat .
In order to deal as much damage as quickly as possible, all warriors should focus on training their primary weapon skill. Improve the weapon skill to at least 1.0 delay. After that, begin to branch out into fighting, throwing, armour, or shields depending on class and character design, but always leave weapon skill turned on during the early game.
Zealots
Like the warrior classes, by far the main focus is to improve weapon skill. Cinder Acolytes can also invest a little in magic, but Scorch alone can only go so far. When Abyssal Knights begin branching out to other skills, invocations should be turned on as well.
Hybrids
Transmuters should get Spider Form castable and pour the rest into Unarmed Combat. Spider Form easily suffices for a killing tool for a while.
Enchanters should train Hexes and a little Ice Magic to increase the effectiveness of Ensorcelled Hibernation and Confusing Touch and put some XP into Stealth. You can ignore Short Blades until your Hexes have enough power to reliably mess up your enemies; if your stealth skill keeps up, you'll one-shot any sleeping foe for a while yet.
Warpers and Arcane Marksmen should focus on improving their weapon skill. They can then focus on getting Blink castable with low failure rate.
Mages
For almost all mages, the actual Spellcasting skill is not particularly important in the early game. It is much more important to get killing spells running, so casters should turn off all skills other than the necessary magic schools. Use 'I' often to check how easily you can cast your important spells. After failure rates for your critical combat spells are less than 10%, branching out into spellcasting and other magic schools becomes appropriate.
A small exception to this are spriggan spellcasters. Spriggans can use their considerable speed to escape almost anything in the early dungeon, so mere survival is not the necessarily first objective - consider Fighting to raise your measly HP.
Wizards, and Venom Mages should focus on getting their low level attack spells and Mephitic Cloud to <10% failure rates. These classes, particularly venom mages, may wish to branch into a weapon so they can kill confused low-level enemies more effectively. Poison's early spells and skill levels are quite cheap, and are often worth for their boost for survival and early game offense.
Conjurers can focus almost entirely on Conjurations. Searing Ray gives you good killing power in the early game and works wonders in corridors; packs of jackals, gnolls or orcs will succumb to it quickly. The Hexes skill is also used for Fulminant Prism, which deals great damage to nearby monsters after 20 auts.
Fire Elementalists want to get Scorch up very quickly -- Foxfire lacks effectiveness in the many, many hallways of the dungeon. Then, your next (and lesser) priority should be to get to Flame Wave.
Ice Elementalists should try and get Frozen Ramparts, which deals respectable and accurate passive damage, as soon as possible. In a similar vein, Earth Elementalists should get Stone Arrow to reduce their need for actual stones.
Air Elementalists are fine with their level 1 and 2 spells, offensively. However, both Swiftness and Airstrike will be useful to have later on.
Necromancers should focus on their spells. If the character wants to dabble in melee, branch out to a weapon skill. Polearms (for reaching attacks through a line of undead servants) or staves (preparing for an eventual staff of death) are recommended.
Other
Artificers should focus on a weapon, as their wands will have respectable power against early dungeon monsters even without much Evocations skill.
Wanderers should wing it. Take a look at your early possessions and try to make a plan.
Delvers can either focus on Stealth, until they make it up to D:2, or just start by focusing on a weapon.
Weapons
In the early dungeon, most characters will find wielding a one-handed weapon with good accuracy to be more effective than trying to hit anything with a large, but slow weapon. Daggers and whips often have good brands on them, while hunting slings (with or without sling bullets) are universally effective in the hands of any character that can find them.
Once you have started training a particular weapon skill, you should usually favour weapons of that skill unless you find something incredible that makes the switch pay off.
Armour
Spell-using characters should avoid wearing anything heavier than a robe in the early game. Leather armor and bucklers may seem dandy, but in the early game, the greatest defense is killing your foe reliably and fast. Once you can cast your spells more reliably, you can consider upgrading to somewhat heavier armour.
Melee builds are typically spell-less right now, and should equip the heaviest armour and shield they can wear without seriously affecting their damage output.
