Monster changes
Undead constitution scores
For the purposes of hit points, undead do not use d12 hit dice. Instead,
they use d8 and have an effective bonus of +3. Template
undead use the characters previous hit dice, with the constitution
modifier of +6 (thus gaining an extra 3 hp per hit dice). The
constitution bonus applies for all appropriate situations, such as fortitude saving throws.
Undead still do not have to make such saving throws for many attacks
(such as poison).
In addition, undead will typically automatically pass constitution checks.
I've made this change because undead fighters should be tougher than
undead mages. Also, undead do not tire, hence they should pass not fail
checks.
