(See last week for the first Underground Elemental Beast "card," of the Charchaeopteryx. Oh...and this week's picture is actually of my own figure that I've had since I was a kid!)
Armor Class 14
Hit Dice 5d8+3 (25 Hit Points)
Speed 30 ft.
Damage Vulnerability Fire
Chill-gore -- Melee Attack +5 // 10 (2d6 + 3) cold damage
Any creature hit by an Iglana attack loses all actions (including reactions and bonus actions) and movement for one round. (They may still perform an action if an ability is used to grant an additional action for the round.)
Iglanas are really cold! After hitting the Iglana with a metal weapon, the attacker must succeed on a DC 15 Constitution saving throw or drop the weapon. This effect may be mitigated by gloves or other insulation for the hands.
