I see on many places people explain LA, ECL, and Racial hit dice for D&D 3.5, but no one really explains which comes first.
Lets say that I am planing on either a Troll half dragon, ogre half dragon or even ogremage half-dragon but I am will not start at level 15. may be about 10th level. So how do I calculate my character's HD?
If I decide on the Troll, at level 10 would I have 6HD + 4LA and 4LA to level up? Or would I have to start with the all the levels of level adjustment and increase HD as I level up further?
At first I was planning on making a halfdragon orc fighter that would specialize in grappling, tripping and other methods of disabling damage output of foes. And then I strayed off my path and wandered to trolls and ogres. So I wanted to calculate how my character ideas would fair against each other and which would be better suited for doing its task.
But I started wondering most about, and thus here is my question, how does D&D treat level adjustment and HD if I can't start at the ECL for that race. If I am ECL 5 and I need to have 3HD and 3LA, how do I continue leveling my character and how does my character look like at ECL5? Do I have 3HD and 2LA with 1LA to gain, to continue on with my levels? Or do I have 3LA and 2HD with another HD waiting before I can continue with CL? Or is this up for interpreting by the GM only?
Thanks in advance.
