Bone Shaman

As all gnolls, you can see the inherent beauty and symbolism in bones, but unlike your peers, you can truly tap into their power. You can spend an amount of hours crafting a bone weapon. The bone weapon must resemble a weapon you are already proficient with. The cost and time to be spent making said weapon is equal to twice the weapon's original cost, rounded up.
If you want to make a Bone Weapon with the attributes of a Trident, that normally costs 5gp, you must spent 10gp and 10 hours making it. (In this case you could spread out the process between a long rest and two short rests)

• You gain +1 to attack and damage rolls with your Bone Weapon. (This effect only works for you)
• You can use any piece of bone, except your Bone Weapon, that has been worked on (ie: a bone flute or earring) as a spellcasting focus.
• You learn any one cantrip from the druid's spell list.
• You learn any one 1st level spell from any class, but it must either be a divination spell or a spell with the ritual tag (in this case you must always cast it as a ritual). You can cast your spell a number of times equal to your proficiency bonus without expending a spell slot, but only while using a bone focus. Once you expend the uses of your chosen spell, you can't cast it again with this feature until you finish a long rest.

Note: If the spell you want to add isn't in the list below, yet it fits the description. Feel free to skip the choice and add it manually.
