Rot Grub ‘Tactics’

Rot grubs are nearly mindless creatures that exist primarily in swarms, a stat block for which is provided in Volo’s Guide to Monsters. They’re a nasty surprise for any adventurer who stumbles across them, since the only way to fight them off once they’ve burrowed into you is to intentionally burn yourself. However, to talk about their having “tactics” is to give them too much credit, and I’m only bothering to write them up because a reader requested it.

A swarm of rot grubs is easy to hit, having an armor class of only 8, but not so easy to destroy. The swarm is resistant to piercing and slashing damage, reflecting the fact that you can kill a lot more grubs with a broad bashing weapon than with a thin cutting edge or poking point. The swarm is also immune to most debilitating conditions, stunned and unconscious being two standout exceptions. The swarm can be blinded, but that doesn’t mean much, since it has 10 feet of blindsight. Except for its Constitution, which is average, the swarm’s ability scores are pitifully low.

The swarm has only one attack, a bite that does only indirect damage. Rather than take place at the moment of attack, the damage occurs at the start of the target’s turn, and it varies in proportion to the number of grubs that have burrowed into the target’s flesh (1d4 per hit). The target must cauterize the bite wound on this turn, or the burrowing grubs will do continuous round-by-round damage until the target is either cured of the infestation or dead.

Stirge Tactics

Stirges are flying, bloodsucking parasites. One alone is a pest, but a flock of them constitutes a threat, and this is how they’ll nearly always be encountered.

Their Strength is pitiful, but their Dexterity is high. This makes them hit-and-run attackers, or rather hit-and-fly attackers, since they waddle along at a laughable 10 feet per turn but fly at a brisk 40. With a Wisdom of only 8, they’re indiscriminate in their target selection, attacking whoever comes closest to them; and with a barely cognizant Intelligence of 2, they know only one way to attack and stick with it regardless of circumstances.

This attack revolves around the use of their Blood Drain feature. Starting from a position in the air above its victim, a stirge dives down to bite with its mosquito-like proboscis. If it hits, it latches on. At the start of each subsequent turn, if its victim hasn’t yanked it loose, it automatically drains another 1d4 + 3 hp from him or her. Keep track of this number for each stirge individually, because once it’s drained 10 hp from its prey, a stirge is sated, and it detaches and flies away at normal speed (potentially incurring one or more opportunity attacks as it departs).

Flying Snake Tactics

You could be forgiven for getting the flying snake confused with the couatl, since they seem to come from the same source material. The easy way to think about it is that the flying snake is the cute, undomesticated wild version, while the couatl is the powerful, otherworldly, people-size version. Or, in Scholastic Aptitude Test format, couatl : flying snake :: angel : titi monkey.

Flying snakes, by and large, avoid combat. First, they’re unaligned, so they have no evil intent to drive them. Second, they’re very low in Strength. Usually, this indicates a preference for fighting in numbers, but snakes are predominantly solitary, not social. (Note that the Monster Manual contains no “Swarm of Flying Snakes” entry.) A flock or nest of flying snakes would be a rare thing, perhaps the result of control by some more powerful being with an affinity for reptiles.

Their Dexterity is exceptional, their Constitution merely average, and they have just 5 hp. If they attack at all, such as if a player character surprises it or stumbles across a nest of its eggs, it will be a shock strike: one hit, then fly away as fast as possible. They can do decent enough damage with this strike—their teeny fangs do just 1 point of puncture damage, but they deliver 3d4 points of toxic venom—to make them a legitimate threat to entry-level adventurers.

Dinosaur Tactics

“Sophistication” is not the word that leaps to mind when discussing the battle tactics of dinosaurs. Most of these ancient beasts are dumb brutes, with extraordinary Strength and Constitution and rock-bottom Intelligence. They also fall into two main categories, plus one variation:

  • Plant-eaters: These tend to be peaceful unless spooked. They may lash out if you invade their space, and they’ll defend themselves if cornered, but most of the time, they’ll mind their own business. If attacked, they’ll usually run.
  • Meat-eaters: These are predators that will hunt, kill and eat any creature smaller than themselves. If they’re hungry—and they usually are—you can count on them to chase and attack anyone and anything they might construe as food.
  • Flying meat-eaters: These behave like their landbound kin, but the fact that they can fly adds an aerial wrinkle to their attack pattern.

The fifth-edition Monster Manual contains stat blocks for six dinosaurs: allosaurus, ankylosaurus, plesiosaurus, pteranodon, triceratops and tyrannosaurus rex. Volo’s Guide to Monsters contains seven more: brontosaurus, deinonychus, dimetrodon, hadrosaurus, quetzalcoatlus, stegosaurus and velociraptor. (All the dinosaurs in Tomb of Annihilation can be found in these two books.)

I’ll look at these by dietary group, from lowest challenge rating to highest within each. Think of this as the dinosaurs’ pecking order, as any meat-eating dinosaur will attack and eat another dinosaur of a smaller size and lower CR, while a higher CR plant-eater, although it won’t actually attack other plant-eaters with lower CRs, may yet decide to muscle in and chase them off if the grazing in an area is especially good. I’ll also link to images, since they’re not all illustrated in the 5E books. Continue reading Dinosaur Tactics
