Hrmmm.<br/><br/>How about something like this? (http://www.d20srd.org/srd/variant/races/reducingLevelAdjustments.htm)<br/><br/>Also, since True Red Eyes isn't useful until you actually activate Red Eyes... how about the True Red Eyes feat remains 'dormant' until 4th level? IE: You don't get the 2 LA increase until 4th level. So for Part 1, he'd be Level 3, ECL 4... just like any other Trueblooded human. Any aesthetic changes can be handwaved (In my old game, at least, the True Red Eyes kid came out of the womb with two big scary glowing eyes. :P)<br/><br/>So... Trueblooded Human w/ True Red Eyes. Part 1: Level 3, ECL 4<br/>Part 2: Level 5, ECL 8.<br/>Level 9, ECL 11 for 11000 xp.<br/>Level 15, ECL 16 for 16000 xp.<br/>Level 18, ECL 18 (If it ever gets that high. :P) for 18000 xp. Total EXP Cost: 45,000<br/><br/>I wouldn't count bloodline levels as ECL, though... or else you'd only be able to start paying it off at level ECL 15.<br/><br/>I suppose then I should say that any NPCs will also abide by this rule. Although not all NPCs are created equal... Maki's going to be point buy 32. :P
