Question what biological traits would be perfect to give to your legion from the horus heresy? Would prefer cheap options that give amazing abilities.

Gene-Seed Traits (free/-100): This perk has two levels. For free, your Astartes receives lesser copies

of the perks you have purchased in the Body of the Primarch section, such as an increased tendency

towards psychic powers, unusual physical strength and durability, and similar advantages, though this

will be lessened down to Astartes level. With the second tier of this perk, you may splice your

biological traits, including inheritable perks and altforms, as you desire into your Legion. They will be

passed down to every Astartes who receives your gene-seed. However, as the Space Marines are like

diluted, weaker sons of the Primarchs, so too will your biological traits be similarly down to Astartes

level upon inheritance. Your children may be durable, and regenerate quickly by Astartes standards, but they will not be unkillable. You may also change up the aesthetics of their forms by adding an

altform you possess into your Astartes, though note that moving too far away from the human form is

likely to result in getting purged; treat the Space Wolves as the furthest away from humanity you can

feasibly get before you’ll have to start getting creative with hiding your Legion’s non-human traits. Additionally, be warned that too radical adjustments may require additional organs implanted into

Astartes recruits which may lengthen the time it takes to turn a man into a Marine.
