The two primary attributes strength and skill affect your characters size and hieght, as well as your basic health and killing ability, will grants you new abilities and also changes your appearance. On a final note, the totals on some abilities will vary due to the alignment penalties and reductions, the total experience need to max all stats and abilities will be very close to the number below.
To max all stats and abilities you need = 1,908,400 experience
Strength
Puting points into the 3 Strength skills adds bulk (muscle) to your Character, as well as adds chest, arm and back hair. Physique makes you deal more damage with each melee hit. Health increases your Health. Toughness increases your natural armour, making you take less damage when struck by magic, ranged or melee attacks.

Skill
Puting points into skill makes your character taller, but does not add any mass at all, a character with lots of skill and no strength looks like an Etheopian, I'm not joking... its kinda funny. Speed increases both your melee and ranged attack speed. Accuracy increases the damage you do with ranged attacks (not magic attacks). Guile allows you to get better deals on buying and selling items, as well as unlocking steal and lockpick abilities.

Will
Putting points into Will turns your hair grey (faster than just age) and adds ruin like markings on your body. These tattoo's, as some people call them, turn blue with more and more Will points spent. Magic Power increases your maximum magic.

Attack Spells
To max all these abilities you need = 381,090 experience
Enflame
This spell is the lamest spell in the game. It requires no skill to use and deals way to much damage over a way too large of area, and on top of that it also knocks your enemies to the ground. Anyone can beat the entire game using just this skill, it is so cheesy.
Level / Experience Needed 1 = 3500 2 = 8100 3 = 22,000 4 = 58,000 TOTAL= 91,600
Fireball
This spell is one of the cooler attack spells, but because of the delay to charge it up and cast, it is difficult to use as a primary spell. Although at the mastered level it deals very good damage, getting it there is hard.
Level / Experience Needed 1 = 500 2 = 4500 3 = 17,800 4 = 54,000 TOTAL= 76,800
Battle Charge
This is a melee style attack where you just charge through enemies using your body as a weapon. At level 1 early in the game it is as good as the mastered at the end of the game.
Level / Experience Needed 1 = 750 2 = 5400 3 = 17,500 4 = 52,000 TOTAL= 75,650
Multi Strike
This is a melee user's attack. You use it and your next attack will hit multiple times based on the skill's level. Each hit deals less damage than a normal single attack would do, but the total damage becomes much greater than a normal attack. If you get good at using this skill before every melee attack you can maximize the damage of your weapon.
Level / Experience Needed 1 = 1200 2 = 4680 3 = 15,700 4 = 43,500 TOTAL= 65,080
Lightning
We all start with this skill level 1 thanks to the guild, it is a decent skill once you have it mastered. Its damage is not high, but you can hit multiple targets and keep em shocked an unmoving. At the mastered level it also decapitates bandits with ease and is quite funny to watch the heads pop off of 5 bandits at once.
Level / Experience Needed 1 = 0 2 = 5760 3 = 18,200 4 = 48,000 TOTAL= 71,960
Surround Spells
To max all these abilities you need = 340,110 experience
Force Push
All it does is knocks everything down in a larger and larger area, at the mastered level it is a huge area. It deals very little damage, it also hurts friendly and neutral NPC's, but it is not even close to being as cheap as Enflame.
Level / Experience Needed 1 = 600 2 = 3600 3 = 12,600 4 = 40,000 TOTAL= 56,800
Turncoat
This is easily one of the cooler spells, turning your enemies into petty minions to kill things for you. Although the enemies you CAN take over is limited and they don't deal much damage, it is a spell you use to support the rest of your abilities, or just have fun with. GOOD characters have an experience penalty on this ability where they have to spend more experience to level it up, and they can never master it.
Level / Experience Needed 1 = 3200 2 = 6500 3 = 16,000 4 = 45,000 TOTAL= 70,700
Slow Time
The universal best skill for any character. For a melee character, you can fight an entire army without ever even being hit, for a ranged character you can stop many charging bandits before they even get to you and a magic user can literally knock their enemies down with one skill, and before those enemies hit the ground you can kill them in the air. It also has uses in mini-games, accomplishing quests and quest boasts. It is on the edge of cheapness, but because you still have to kill your enemies it isn't that bad.
Level / Experience Needed 1 = 2000 2 = 6580 3 = 18,800 4 = 47,500 TOTAL= 74,880
Drain Life
This skill is not very tough at low levels, but at high levels you can suck the life out of your enemies and actually kill them with it. It is a spell that only EVIL characters can master and GOOD characters take an experience penalty where they have to spend more experience to learn it.
Level / Experience Needed 1 = 2800 2 = 6750 3 = 16,500 4 = 44,000 TOTAL= 70,500
Summon
This is another support skill, as in you can't rely on your summoned creatures to kill everything for you, it would take way to long. The way the spell works is that it starts out as a wasp, and if the summon kills an enemy, it can take the form of that enemy, so if it kills a bandit, the summon is now a bandit. The types of enemies that the summon can be is extremely limited and for that reason, not very good. It is a spell that you can have some fun with though, having Turncoat, Ghost sword and a summon can make for a decent strengthed force, but the experience it takes to master those three skills doesn't match up to the power you could have with that experience elsewhere. It is also a spell that EVIL characters take an experience penalty on where they have to spend more experience to learn it and only GOOD characters can master it.
Level / Experience Needed 1 = 1800 2 = 5030 3 = 14,400 4 = 46,000 TOTAL= 67,230
Physical Spells
To max all these abilities you need = 403,150 experience
Physical Shield
This spell is almost as cheesy as Enflame. I swear it must be a bug they forgot to eliminate, but if you have Physical Shield on, your combat multiplier WILL NOT GO DOWN when you get hit. Because of that, you will always have a high combat multiplier and be getting an insane amount of experience. A quick example is a game I played where I got physical shield as fast as I could (after the wasp quest) and always had it on, then I played another game where I NEVER used it, by the end of the game when just playing through normally (8 hours per game) the game with Physical Shield had earned nearly 800,000 more experience than the other character, and the other character didn't even earn 800,000 experience in total! It is incredibly cheesy and I never use it any more, EVER. It is a spell that only the GOOD characters can master, EVIL characters take an experience penalty on it where they have to spend more to learn it.
Level / Experience Needed 1 = 900 2 = 5350 3 = 17,700 4 = 45,500 TOTAL= 69,450
Berserk
This is one of the better skills, both balanced wise and usefullness. If you have it on you deal more damage, take less damage, run faster, your melee attacks knock your enemies down (which makes it balanced since you can't hit them while they are down) and you also look very cool. It is however, a melee skill, so ranged and magic characters will find little use for it. It is also a spell that only EVIL characters can master and GOOD characters take an experience penalty on it where they have to spend more experience to learn it.
Level / Experience Needed 1 = 1600 2 = 6210 3 = 20,500 4 = 51,000 TOTAL= 79,310
Assassin Rush
A lesser form of Battle Charge, this skill crosses a set distance very quickly, but deals no damage. If you lock onto an enemy and use it, you will appear behind them giving you a second or sometimes more, to have a first attack. At the mastered level it does cover a lot of ground very quickly, but again, not very useful at killing large numbers of enemies. Against single targets though, it is a good opener.
Level / Experience Needed 1 = 400 2 = 2700 3 = 8100 4 = 20,000 TOTAL= 31,200
Heal Life
What do I need to say? It heals life, at the mastered level it does heal a lot of life, but costs a lot of mana. It also is great for keeping allies (mercinaries or people you are rescueing) alive. It is a spell that only the GOOD characters can master and EVIL characters take an experience penalty on.
Level / Experience Needed 1 = 2300 2 = 5850 3 = 15,900 4 = 49,000 TOTAL= 73,050
Ghost Sword
This spell would be very useful if the swords did more damage or if they attacked more often. But they don't, so it is just another support spell that you should use with other spells like Lightning, or Berserk, or even just when you're a ranged or melee character. I do like the spell, but in terms of usefullness, it isn't the best by far.
Level / Experience Needed 1 = 2500 2 = 6300 3 = 17,200 4 = 51,500 TOTAL= 77,500
Multi Arrow
The only true skill for the ranged characters, it makes your next few shots split into multiple arrows. Each arrow deals less damage than a normal single arrow, but at the mastered level the total damage is far greater than normal damage. The biggest downfall to this skill is the arrows split into a wide arc from your character, making it difficult to hit enemies in close quarters (like in dungeons) or if the enemy is too close, the arrows will just not hit them.
Level / Experience Needed 1 = 1000 2 = 5140 3 = 19,500 4 = 47,000 TOTAL= 72,640
