Power Cost

From Hellgatewiki.com

Power cost of skills varies, depending on character level.

The formula for power cost of skills:
power cost = basic power cost * (1 + (clvl - 1) / 50)

Where:

• basic power cost - cost of skill at character level 1
• clvl - character level

For example: if basic power cost is 36 then at clvl = 23, power cost = 36 * (1 + (23 - 1) / 50) = 36 * 1.44 = 51.84

PS formula is discovered by watching skill power cost differences from level to level and may not be absolutely true, but it just works :)
