Bind Familiar

You transmit the idea that you and your allies are friendly to a willing beast, gaining it's trust and creating a lesser soul-bound between you and that creature, the gemstone is used to maintain the bind and becomes a bound talisman that keeps both of your souls united, if the talisman is broken the spell ends, you can also detect and see the bound talisman through walls if you are not holding or carrying it. You can only bind your soul with 2 creatures at once.

While the bound is maintained between the caster and the beast, the beast will avoid going more than 200 ft away from you at all times, and will only do if under magical effects that forces them to move away, you can also sense their presence in that radius even if you can not see the familiar. they will act independently from you, but are also going to treat you well if the bound is maintained willingly, obbeying most of your commands that are given in a language they can understand.

the talisman will glow while it is in a 200ft radius of the familiar, the glow will be fainter or stronger depending on how far you are from the familiar, the talisman's glow will not allow you to see in the dark, but you will be able to see it in the dark, if it gets out of range from the familiar, it will lose all of it's glow and only be lit again once the familiar is detected within range.

if the bounded creature dies, you can cast this spell again with a Material cost (the talisman bound to it or a beast's heart, a gallon of your own blood and a handful of grass) to ressurect them in a newly summoned body, the new body will be the familiar's original form when you soul-bounded with it and the talisman will not be consumed if used for the spell.

the spell  allows you to bind more creatures at once at 5th level (3 creatures), 11th level (4 creatures) and 17th level (6 creatures).
