Rank 5- Total of -5 AP
- NO Skill limit
Some skills have 4 or 5 base AP cost so they would cost 0 ?
Should better be a percentage.
-10% to AP per level
+10% to effects per level
Of course the base AP cost of high level skills should be higher to compensate.
This is enough to make specialization usefull.
Then lower the level requirements by 1 or 2, and maybe increase the attribute requirements by 1.
This way a specialist can have access to higher skills. He will be capped by his level while other classes will be capped by the attribute.
