Avarek

Constant Spells — A constant spell affects the monster without the monster needing to cast it, and its duration is unlimited. If a constant spell gets counteracted, the monster can reactivate it by spending the normal spellcasting actions the spell requires.

Prickly Defense — The avarek withdraws beneath its spines, presenting a defensive, spiky exterior. It gains a +2 circumstance bonus to spine Strikes and AC. Any adjacent creature that attempts a melee attack against the avarek takes 1d6 piercing damage per attack, regardless of whether the attack hits.

Prickly Defense lasts until the avarek uses a move action or makes a Strike with any weapon other than its spines.

Rolling Assault — The avarek curls into a ball and rolls rapidly, impaling enemies with its spines. The avarek Strides twice and makes up to two spine Strikes at any point during its movement, each against a different target within reach.

These attacks count toward the avarek's multiple attack penalty, but the penalty doesn't increase until after the avarek makes all the attacks.

Sneak Attack — The avarek's Strikes deal an additional 2d6 precision damage to Off-Guard creatures.
