Does anyone have Dark elf stats or abilities?

For stats using elf warrior and archer stats from the Elf Quest Book.

I don't know, it depends on how different do you think are the Dark Elves compared with other types of elves.

For stats I would use the same as the Elves from EQP, which would fit with Warhammer lore, where all kind of elves have the same basic stats. Such stats are already high, so I would not empower them too much, but of course it is just an opinion.

If you want for Dark Elves some special ability, well I would give them the ability of using repeating crossbows (the rest of elves don't use them) or some kind of special gear like elven cloaks which improve their defence roll, or a stealth ability.

I like the repeating crossbow idea. In the EQP the elf archer has...
