Ability (Su): Description
Rend(Ex): If Grendel hits with two or more claw attacks against the same opponent, he latches onto the opponents body and tears the flesh. This attack automatically deals an additional 2d6+19.
Fast Healing(Ex): Grendel heals 5 points of damage each round so long as he has at least 1 hit point. This doesn't allow Grendel to restore hit points lost from starvation, thirst or suffocation, and it does not allow him to regrow lost limbs or reattach body parts.
Improved Grab (Ex): If Grendel hits an opponent that is at least one size category smaller than itself with a claw attack, it deals normal damage and attempts to start a grapple as a free action without provoking an attack of opportunity. If it gets a hold, it can rake. Alternatively, Grendel has the option to conduct the grapple normally, or simply use it's claw to hold the opponent (-20 on grapple check, but the feral creature is not considered grappled). In either case, each successful grapple check it makes during the consecutive rounds automatically deals claw damage.
Pounce (Ex): If Grendel leaps upon a foe during the first round of combat, it can make a full attack even if it has already moved.
Rake (Ex): If Grendel gets a hold can make two rake attacks at its full melee attack bonus with his hind legs. Each Successful attack deals 2d6+6.
Smite Good (Su): Once per day Grendel can make a normal melee attack to deal extra damage equal to its HD total (+8) against a good foe
Grendel's claws and bite are treated as being magical weapons fro overcoming DR.
------
This is with all the templates applied, but I don't know how to properly apply all the attacks here; I was thinking maybe Multiattack would be a great feat, rather than Weapon Focus, but like I said I'm not sure how to apply em together.
I also got lazy and didn't equip him, or make the rage changes, but these are easy enough, and generally pretty specific DM-to-DM (equipment-wise).
I think Grendel here'd be great for a first-round killa, with his Pounce, rake and redn abilities
Anyways, that's all I got for now, if you need an clarifications on anything, feel free to ask
Hope this helped!
