rookie female mule deer fawn 37hps

This is effectively a squirrel, this is not right at all, yes its young, but it should have a minimum base hp rate of at LEAST 25% or more of the max hp of the creature. If max hp is 450hp (? I have no idea?) than 112hp could be a good theoretical minimum hp.

yound adult greater mule deer buck 314hp 0.80 deer that dealt 37.75 damage to me without armor, this hurt alot and means he could kill me in 6 hits. I deal 58.76 damage to him with charge attack while doing 33.37 with a regular attack.

This means I would need to hit him 10 times while he would only need to hit me 5-6 times with 220hps.

Since your not expecting 95% of people to have this much health I would say that this is too much damage.

The health is fine, but the damage means that this guy is going to 2-3 hit most people you intend to be able to solo it.
