I am working on moding Captian Ubi Sunt into a Scoundrel 2/ Soldier 2 and I am tying to calc his HP
So a Scoundrel gets 18x3 +con bon at first = 54+2 =56, then (1/2 (1d6) + con bon)/lvl scout = 3+2 =5/ lvl scout, and  (1/2 (1d10) + con bon)/lvl soldier = 5+2=7/ lvl solder.
therfore (if I have this right Ubi's HP = 56+5+7+7=75.
is that right?

No you do not get 18x3.. you get 6x 3 = 18.     So 18  + Con  = 18+2 = 20 hp at first level, not 56.  It's easy, just triple the normal HP at CHARACTER level one.  Then why are you dividing hp??  It''s just leke D&D3.5/Pathfinder.. each level after you gain the 1/2 TH HD + Con HP of that class

so rogue l2 = 1d66+2 = 3+2 =5 
Soldier 1 = 1d10+2 = 5+2 = 7
Soldier 2 = 1d10+2 = 5+2 = 7

So you'd have 39 HP.   BUT I need to fix that, I have been letting characters roll HP with our usual house rules.  roll the HD and take minimum one above 1/2  then add Con      so soldier hp = 6-10+ Con per level, rogue = 4-6+Con

So with my house rule you'd have between 40 and 52 hp.
