Mastiff DnD 5E Monster

Hello zoologists of all shapes and sizes! Welcome to my spellbook and thank you so much for clicked on to the 41st episode of our beast series. Today we have an amazing episode in store for us. As we are taking a look at the best boy and/or girl i don’t discriminate 🙂 We are looking at the mastiff.

This amazing majestic animal is found in the basic rules and it’s considered to be cr 1/8. It also typically dwells in forest hill and urban environments at least according to the source material. The mastiff has a very interesting history, it was bred by humanoids for humanoids and it is a quite a loyal and keen creature.

They can be trained as guard dogs, hunting dogs and war dogs and halflings and other small humanoids ride them as mounts which is so amazing. I love him now let’s take a quick look at his stats here.


He’s considered to be a medium beast that is unaligned. It has an Armor Class of 12 although i could argue that armour to be tailor-made to them. They have a 5 hit points calculated by rolling 1d8 and adding a modifier of 1. it also has speed of 40 feet which puts them above most other medium creatures.

  • Type: Medium Beast, Unaligned
  • AC: 12
  • HP: 5(1D8+1)
  • Speed: 40feet.

That being said looking at their main see that they are strong and dexterous rather hardy and wise as well. They’re not particularly the brightest and they are not the most charismatic either. I’ve actually been given charisma a decent amount of thought lately.

I think the reason why a lot of these beasts are such low charisma is just due to the fact that they can not communicate. Almost every charisma ability is something to do with communication it really is an indicative of attractiveness. So that’s why at least to the best of my knowledge. If you agree say so down in the comment section, if you disagree let me know why.

  • STR: 13(+1)
  • DEX: 14(+2)
  • CON: 12(+1)
  • INT: 3(-4)
  • WIS: 12(+1)
  • CHA: 7(-2)

In skills section he does have a +3 to perception and he has a passive perception of 13. He also has an access to keen hearing and smell which give him advantage on perception checks they rely on hearing or smell. which is a decent amount of them.


Here in dungeons and dragons role playing game all the mastiffs are impressive hounds prized by the humanoids because of their loyalty and also for their keen senses. The mastiffs can be trained as the different types of dogs such as guard dogs, hunting dogs, and war dogs. Actually, the halflings and also some other Small Humanoids ride them like the Mounts.


Keen Hearing and Smell: Here the mastiff has an advantage on the Wisdom (Perception) checks which are rely on hearing or on smelling.

Taking a look at his actions here. You’ll see his bite attack. Is considered to be a melee weapon attack, +3 to hit, range of five feet. The rest is given below.


Bite: By using this bite action this dnd monster can make a Melee Weapon Attack: +3 to hit, reach 5 ft., one target. It also make Hit: 4 (1d6 + 1) piercing damage. Suppose, if a target is one of the creatures and then it should be succeed on a DC 11 Strength saving throw or else be knocked prone.

I really do love the mastiff, i think they would work great in the way of hunting companions or packs of them roving a city. Causing trouble i think that’d be rather interesting in terms of plot hook or storyline. Outside of that most nobility is quite likely to have them posted as guard dogs. So this could make an excellent obstacle for your party members to overcome in creative ways.
