 This damage is then modified as follows:
-*'''AC reduction''': Unlike most melee attacks, constriction is not reduced by a random number between 0 and [[AC]]; the damage reduction is a random number between 0 and <code>1 + AC/2</code>. This means that constriction bypasses half of the AC.

-While the target is constricted, it will take an increasing amount of damage each turn, will be unable to move in any direction, and will suffer an [[ev]]asion penalty (-3 EV for the player; for monsters EV is divided by <code>2 + body [[size]]</code>).
