Im kinda confused, how do the extra HD, etc work out with the special mount then?
A cohort would normally be up to 2 levels below your level.
The special mount gives your mount extra HD depending on your paladin level. Would they count for the up to 2 levels, etc thing?
So a level 20 paladin......+8 HD for a unicorn........if we say LA is bumped up to +6 for being a special mount, that would make it a 12 HD unicorn, with +6 LA, under the cohort rules. Then the +8 HD would make it 20 HD with +6 LA?
