Evil Domain

[MtainEer]

Taking Evil as one of your cleric domains does not give any additional stats to your Balor, thou the wiki says it does.

All Planar Summons
Receive the following bonuses: ## An AB, AC, strength, dexterity, and constitution increase equal to the sum of the following: ## + 3 if the caster is a planar race...
## + 2 if caster is a good-aligned Cleric with the Good Domain, or is an evil-aligned Cleric with the Evil Domain. This does not apply to Dragon Knight summons

You are correct, it does not give a bonus to your balor. Because balor is a form of Dragon Knight.

This does not apply to Dragon Knight summons
