Glamour Bard can become magically beautiful at 14th level.
Yeah, ok.
The Glamor Bard description mentions ‘unearthly beauty’ and ‘otherworldly lovely and fierce’ appearance, and links it with Charisma magic and charm effects − even associates it with the Eladrin by name.
The description needs to be more explicit about the sexually seductive aspect of the magical beauty to portray the archetype. But it hints at it, and a player can make a point to play it that way.
For the sake of the archetype, the ‘unearthly beauty’ appears at level 6 in Majestic Mantle.
I want the level 3 ‘seductive’ Enthralling Performance to mention magical beauty.
Plus have something at level 1 to express magical beauty such as a choice of cantrip.
(Also have a feat called Comeliness, for how nonmagical beauty can enhance Persuasion checks and Charm effects for those in line-of-sight. Oppositely, also have a feat called Hideousness that can enhance Intimidation and Frighten effects for those in line-of-sight.)
(Even game designers seem to forget that high Charisma can mean terrifying.)
The Glamor Bard hints at different kinds of archetypes:
• Sexually seductive (beauty)
• Artistically stunning (art)
• Majestically regal (power)
I actually like each of these possibilities. I wish each of them was spelled out more explicitly as a possible option, for a character concept.
Also, I like the fact that the ‘seductive’ charm-related mechanics are all gender-neutral.
The bottom line is. The Glamor Bard satisfies my earlier call for a sexually seductive archetype, but the player needs to make a special effort to make it work.
Note: as a race archetype, I want the Eladrin to be a +2 Charisma race. The 4e Eladrin that can be +2 Charisma and +2 Intelligence, conveying a magical race of enchanting beauty and eloquent logic, who masters both Bard and Wizard and Psion, with rational and hedonistic eldritch courts, is a character concept that is important to me, that remains poignantly lacking from 5e.
