From their Nymph blood, Elf-Nymphs are able to draw upon nature’s magic.

You know druidcraft, and two spells from the druidic spell list. The combined level of the spells must be equal or less than your level/3(round up) and cannot be higher than 4th level. You can cast each spell once after a long rest, it regains back after a short rest if you take a short rest in a forest. 

You use wisdom as your spellcasting ability score if you do not have any spellcasting ability score and are considered trained.

Accustomed to life  amidst the deepwood you have superior vision in dark and dim conditions. You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can’t discern colour in darkness, only shades of grey.

The light weight and agility that Elves and Nymphs possess means that they are able to use their innate grace and speed to conduct feats that would otherwise require brute strength.

You can choose to add your dexterity modifier to the Athletics Skill instead of strength. However, this skill is still considered to be a strength based skill and as such benefits from traits or feats that improve strength based skills and does not benefit from traits or feats that improve dexterity based skill

Regardless of gender, combining the beauty of Elves and Nymphs, those of their descendants have beauty so haunting, graceful and fine that those who look into them are often stunned by the sight.

Those who look at your full face within 30 feet, must make a DC12 + your charisma modifier will saving throw. If they fail they suffer these effects depending if they are in combat with you or not. This does not apply to creatures(such as dragons, monsters, skeletons(DM discretion)) who would not care about your looks

• Attacks against you have a -2 to hit from a creature who comes under the effect as your unnatural beauty confounds them and causes their strikes to fumble. 
• They have disadvantage on skill checks as they are singularity focused on you

• If they are not hostile to you, they will continue staring at you, fascinated by your beauty and have their movement reduced by half. 

A creature can repeat the saving throw every turn in combat or every minute out of combat . This effect is broken if the Elf-Nymph does an action that threatens, attacks the creature or does any act that is considered hostile.. Once the effect is broken, the creature is considered immune to the effect from the same Elf-Nymph. Those who succeed the saving throw will feel a sense of unease and would likely have a negative opinion against the Elf-Nymph(DM discretion). This ability is always active unless they cannot see your full face

Elf-Nymph’s thanks to their intricate connection with nature, are able to commune and travel through it with ease.

You ignore difficult terrain that is part of a tree, underbrush, or some other forest growth.  You can breathe underwater for up to one hour and have a swim speed of 30 feet. Additionally, while fully or partially(50% of your body) submerged in water you ignore disadvantages on any saving throw.

Elf Nymphs are not particularly strong or resilient away from the presence of nature

When outside a forest or not in water, you gain disadvantage on fortitude saving throws against non magical effects and disadvantage on strength checks.

Elf-Nymphs combined the inherent grace and dexterity of both their parentage, allowing them to react to danger quickly and with unsurpassed grace, 

The fey-like nature of your nymph blood combined with the protection Lirineoix gave to all Elves makes controlling their mind essentially impossible.

Against effects meant to charm, possess, dominate or any sort of mind control manipulation effects, your critical failures and failures count as success and your success counts as Critical Success.
