5th dnd – Are these homebrew shields balanced?

Since I've glanced at the PHB's equipment tables, I was not satisfied with the lack of different protection options. I guess it makes sense in the 5th philosophy to make everything as simple as possible. And if shields do nothing but give AC bonuses, there's really no reason to have more than one type of shield (mechanical) because people are going always choose the one with the highest bonus. Unless of course, there are different types of shielding skills, which creates complexity … and so on.

Whatever it is, I decided to deal with this issue and here is what I proposed.

Shields of Light

Light shields are rather small shields, with a diameter of 20 cm for particularly small shields and up to 50 cm for shields with comparable peaks.

Buckler Shield

With a shield shield, you can ward off using your reaction when you are hit by an attack. This allows you to add half of your DEX modifier (rounded up) as a bonus to your normal AC against all attacks from the source of the trigger attack. This bonus applies whether or not your CA includes your DEX modifier.

Shield

It is essentially a large shield with a pointed tip in the center or small spikes. As a bonus action, you can perform an attack with the point (s), with a range of 5 feet and inflicting 1d4 + STR damage during a hit.


Heavy shields

Heavy shields are notably bigger than light shields. They include, for example, heating shields (usually made of metal) 60 cm high and above, or kite shields (wood or metal) up to shoulder height. And of course, standard round shields of a diameter sometimes greater than 1 meter, like the Aspis shields used by ancient Greeks, also fall into this category.

Heavy shields do not grant bonuses beyond what is shown in the chart.


Super-heavy shields

Super-heavy shields include Tower Shields, such as the Roman scutum or medieval pavement, and Stone Greatshields, which may be round or even similar to Tower Shields, although they are made of a different material.

Since super-heavy shields are usually almost as big as an average human, small creatures can not use super-heavy shields because of their heaviness for creatures of this size.

Shield of the tower

Tower shields allow you to use a bonus action to shelter you behind the shield. As a result, you get coverage of three quarters until the start of your next turn, replacing the normal bonus from +3 to AC by +5. Magic bonuses always apply in addition to that. While you receive this bonus, you have a disadvantage on the opportunity attacks you make.

Stone Greatshield

A stone greatshield confers immunity against the effects that move you against your will, as well as an advantage over thrust tests if you use the shield for thrust. Stone Greatshields count as unusual magical items as they require magical enhancements to reinforce the stone enough to counteract its usual fragility.


Shield modifications

Wooden shields

Many shields can be made of wood, which is actually the most common variant (as opposed to metal) among guards or other ordinary citizens. These shields were often painted with the emblem of the one who served the user, such as the emblem of a guild or a king. These shields have the advantage of being cheaper and generally lighter than their metal variants.

However, being made of wood, they are not as effective against fire as metal shields (although metal shields, because of their warming up, are also not ideally used to protect themselves from the brim of fire of a dragon for longer periods). In mechanical terms, they do not offer AC bonuses against attacks that inflict fire damage and can not be used with the Shield's stunt against spells or other effects that inflict fire damage, such as Fireball spell or fire attack. trap that requires DEX backup.

Mithral metal shields

Most metal screens are made of iron or bronze. However, at high costs, it is possible to buy or put into service shields in mithral. Usually, only dwarven blacksmiths have both the skills and equipment needed to forge mithraal shields.

The mithraal shields, compared to their regular variant, weigh only half, do not require minimal resistance, but they also cost 10 times more, which reflects the scarcity of the material and the talent needed to forge it. Shields, spike shields, heavy metal shields, and tower shields can be in mithral.

Silver shields

Shields can be silvered at the same price as weapons (100 gp, see PHB p.148). A Silver Shield may allow you to deal damage to a creature that is resistant or immune to magic damage, but susceptible to Silver Weapon damage. This bypass of resistance, so to speak, applies if you use the shield as an improvised weapon or if you use a spiked shield.

Shield skill

If certain effects (such as your class or an exploit) allow you to control the shields, you can use light and heavy shields, but not super-heavy shields. To gain skills with these, you can take the tour de force of the shield master. The dwarves, however, have an innate connection with the stone and can therefore use stone greatshields even if they possess only the usual control of the shield. They must also always meet the requirement for suspicious transaction reporting.

Improvised weapons

All shields can be used as improvised weapons that deal 1d4 blunt damage to a hit. You do not need to master the shields to use them as improvised weapons.

For the question to be narrower, I suppose the main goal should be to determine whether the most powerful shields (ie, super-heavy shields) are counterbalanced by the 5th combat system. louder feat), or if the weakest shields are under or overpowered. The heavy shields are pretty much identical to the default shields, except they have STR requirements (which is quite relevant for DEX-based fighters, I could delete it now that I think about it) and a different cost and weight, although these two do not matter my experience (at least not in this range of values).
