A Tier 2 Skill will cost twice as much. A Tier 1 Skill that has reached Rank I and is being pushed towards Rank II would cost the same.

So when you spend 1 Skill point on a Tier 1 Skill that hasn't reached Rank I, you would get 0.1 Skill Progression per Skill Point. So getting Crafting I right off the bat, that would cost 10 Skill Points.

When you spend 1 Skill point on a Tier 2 Skill, or a Tier 1 Skill that has reached Rank I already, you will get 0.05 Skill Progression per Skill Point. So if you spent 10 points to get Crafting I, then spent more on it to get Crafting II, you would have to spend another 20 points. If you wanted to get Fireball to Rank I, that would also cost 20 points.

Since you only have 30 to work with right off the bat, it probably seems like there aren't enough skill points to catch up with most of the other players. However, you could potentially just spend 1 or 2 points per Skill so that they're on your UNUSABLE list--and then, by practicing in-game, accelerate the progression of those skills. It's up to you guys whether you would like to have one stronger skill added to your abilities, or if you want to spread out so that you have a variety of skills later on.

Also, remember that your Species Skills are a little different. Since you're a Wisp, you would automatically start with Mana Orb at Rank I. Getting Mana Orb to Rank II would actually only cost you 10 Skill Points, though after that it would cost twice as much like the Tier 2 skills. So if you wanted to be an uber-specialist, you could potentially dump all your points and start out with Mana Orb Rank III. It would probably spend all your MP every time you used it, but it would also one-shot any other NPC Wisp or Pixie and do SIGNIFICANT damage to any other creature.

Whatever you decide to do, think carefully! ;)
