The Temple of Elemental Evil Cheats

Must have official patch 2.0 installed.

Bring up the console by holding shift and ~. Then type the following string with X being the number of the party member you want to target -1, and with Y being the number you want that character's pre-con-modified HP to be:

game.party[X].stat_base_set(stat_hp_max,Y)

Example: game.party[2].stat_base_set(stat_hp_max,20) will set the third member of your party to an HP max of 20 + (character's con modifier * character's level).

Code may not work right until you've played for a while. If it fails, try typing this line into the console first:

from utilities import *

When making a new character push the Reroll button as many times as you want- the higher the better (it will say how many times you pushed the Reroll button). Then go to the Advanced tab. Where the stats were on the Basics page you can double click on one of the boxes where they were and the number will change to how many time you pushed the Reroll Button. You can then drag this high number over to the stat block you want.
