Any two stats increase by 2 or any four stats increase by 1

Your speed on land is 30, but this can change later

As a mixture of creatures and skin patchwork, everyone finds you appalling, if not, at least a little disturbing.

This is supposed to reduce your max charisma to 15 or just reduce what ever you have in charisma by 3, but IDK how to do that.

As a being created from multiple creatures, you have some of their traits.

Normally, you should roll three d10 to see what features you get, or you pick what feature to take with DM's permission, or the DM's choice to align for backstory reasons.

You may roll a d10 three times on a table of ten traits to put on your character, allowing you to have three traits from ten. Reroll if you get the same thing twice.

1 - Bugbear arms. you gain 5ft of melee range

2 - Gills. you can breath for an hour underwater

3 - Rabbit legs. you gain 5ft of movement

4 - webbed feet. you gain a swim speed of 20ft

5 - Poison Resistant. You gain resistance to poison damage and have advantage against being poisoned.

6 - Deep gnome eyes. You gain 60ft of darkvision

7 - Aarakocra wings. you gain a flying speed of 5 ft

8 - Lizard folk hide. you gain 1 to your AC

9 - Firbolg instinct. you can move across nonmagical difficult terrain without spending extra movement

10 - Tabaxi claws. you can deal 1d6 slashing damage as an unarmed attack

Because you don't resemble any race, you look like a very unsettling monster, so you gain a bonus of 2 to intimidation.
