Grab

Pierce Armor [>] The smilodon makes a fangs Strike against a creature it is grabbing. If the attack hits, the creature is knocked prone; if the creature is wearing armor with hardness 10 or lower, the armor is broken. If this Strike breaks a creature's armor or damages a creature who is unarmored or wearing broken armor, the creature also takes 2d6 persistent bleed damage. This Strike doesn't further damage armor that's already broken.

Pounce [>] The smilodon Strides and makes a Strike at the end of that movement. If the smilodon began this action hidden, it remains hidden until after this ability's Strike.

Sneak Attack The smilodon deals 1d6 extra precision damage to creatures that are flat-footed.
