Watching my son playing FF16 reminded me how awful this monster is, 5e version for my game. Works well in any science-fantasy setting in particular.
MALBORO
Siege Monster. The malboro deals double damage to objects and structures.
ACTIONS
Multiattack. The malboro uses Pacifying Spores and then makes two Tentacle Slam attacks.
Tentacle Slam. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 16 (3d6 + 6) bludgeoning damage.
Rock Spit. Ranged Weapon Attack: +10 to hit, range 60/180 ft., one target. Hit: 28 (4d10 + 6) acid damage.
Pacifying Spores (3/Day). The malboro ejects spores at one creature it can see within 5 feet of it. The target must succeed on a DC 17 Constitution saving throw or be stunned for 1 minute. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
BONUS ACTIONS
Bad Breath. The malboro exhales an insidious gas in a 60-foot cone. Each creature in that area must succeed on a DC 17 Constitution saving throw or suffer a random condition for 1 minute (see below). A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If the target suffers the same condition twice it takes 4d6 damage to a random ability score:
The malboro is immune to the conditions imposed by Bad Breath.
