SNAREVINES
These semi-sentient plants lie dormant upon the forest floor until they detect vibrations through the ground. When the source of those vibrations draws close the vines lash upwards, ensnaring limbs and weapons alike.
When a unit finishes an Advance or charge move within an area of jungle terrain, roll one D6 for that unit; on a 1, subtract 1 from hit rolls made for that unit until the end of the turn.
DEADLY PREDATORS
Even the clamour of battle is not enough to stop these apex predators from attacking warriors on the outskirts of the battlefield. Such beasts care nothing for the affiliations or intentions of those they hunt; they simply seek to sink fangs and claws into their next meal, and will attack with ferocious fury in order to do so.
At the start of the battle round, determine which unit on the battlefield is closest to a battlefield edge and roll one D6; on a 4+, that unit suffers D6 mortal wounds.
