Unearthed Arcana

Unearthed Arcana has some good stuff, but it also has unnecessary power creep and other issues. It is effectively a collection of rules from Dragon mag and other sources, and it's best not to apply the entire thing to a campaign. This page lists the rules used and not used by Demon Idol. Your campaign may differ, of course.¹⁾

Rules used

Magic items, including the updated random magic item tables.
All new spells.
Illusionists roll for starting spells on the new categorical tables provided, rather than rolling on the full gamut of spells.
Thief armor bonuses and penalties.
Extended weapon proficiency list.

Rules adapted

Character tokens allow a players to add the new races and classes to their stable by accomplishing significant quests (see that page for more info).
New plate armors are only available as magic items. They cannot be bought or crafted.²⁾

Rules rejected

Weapon specialization.³⁾
Cantrips.
New class and race level limits, unless the character was made with a Character Token.

¹⁾

Anecdotally, magic items and spells are the things I hear most commonly used in other interpretations. Cantrips and weapon specialization are the things I most often see rejected. Especially cantrips.

²⁾

Fighters and clerics do not need a buff.

³⁾

As though fighters need a buff. Hah! Not to mention it encourages characters to focus on one or two weapon types. It's better for the game if characters have incentive to use a variety of weapons (magic or otherwise).
