Composition instead of inheritance c#

Question

I have a class
Monster
{
move()
attack()
}

we can create:
melee monster : monster
overr attack()
ranged monster : monster
ovverr attack()
flying monster : monster
overr move()
swimming monster : monster
overr move()

how to create FlyingRangeMonster and MeleeSwimmingMonster without duplicating code? I suppose we should abandon inheritance and use composition. How to realízate it in this case ?
Thank you!

Answer 1

How about an interface monster with methods move and attack

Answer 2

but if we create an interface we will duplicate code (e.g. melee monster and swimmingmeleemonster will have same realization of attack method)
