Avarek

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.

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.

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.

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