As you know, you need to complete quests to unlock skills at level 70 or higher. Until recently, those quests required very expensive items and so their completion was impossible for new players.
This has been changed and those quests were drastically simplified. You don't need expensive items anymore and basically everyone can get them very easily with very low expenses.
All skills now require 
Spell Stone Powders and needed amount is only depended on level of skill.
To obtain Spell Stone Powders you will need accessories to disassemble (old or normal - doesn't matter). Disassembling items is possible with [Mysterious] Narki located in Moradon at 726, 744. You will always get 1-5 powders per each disassemble attempt with following probability:
| Accessory | Probability | Amount |
|---|---|---|
| Old Accessory | 20% | 1 Spell stone powder |
| Old Accessory | 40% | 2 Spell stone powders |
| Old Accessory | 20% | 3 Spell stone powders |
| Old Accessory | 15% | 4 Spell stone powders |
| Old Accessory | 5% | 5 Spell stone powders |
| Unique (normal) Accessory | 9% | 1 Spell stone powder |
| Unique (normal) Accessory | 20% | 2 Spell stone powders |
| Unique (normal) Accessory | 40% | 3 Spell stone powders |
| Unique (normal) Accessory | 20% | 4 Spell stone powders |
| Unique (normal) Accessory | 9% | 5 Spell stone powders |
