Another Math Question (Sorry) :D

Here's another:

Ochre Jelly: Level 3 Elite Brute (300 xp)
HP 102
AC 18
Fort 16
Reflex 14
Will 14
Con: + 1
Slam Attacj


According to this math to get brute hp's (10 + con + (level x 10) ) i get "41" .. then double that for an elite and I get "82" HP's. Is that right? Thats quite a bit lower than the original HP's.

As well, I added +2 to attack.. and gave a twice a turn slam attack.

. ive tried to convert it and dropped it 82 HP and given it a double attack, also dropped its AC and Fort.

The ochre jelly has a very unusual ability: Split. It's most likely that they gave it atypical HP because of this ability. You'll find similar oddities when dealing with monsters with insubstantial, I believe.

I see your problem - you added the Con MODIFIER (+1), but you're supposed to add the CONSTITUTION SCORE (11). That would be 10 + 11 + (3*10) = 51, which you double (for an elite) to get the 102.
