Bastion Breaker

Bastion Breakers are living siege weapons that enhance their destructive prowess using advanced protocol systems, integrating them seamlessly into their design. These automaton warriors are masters of schematic designs that amplify their abilities to dismantle fortifications and overcome any obstacle. Whether you discovered the schematics in ancient ruins, learned them from a forgotten artificer, or developed them through rigorous experimentation, you have mastered the craft of embedding these powerful protocols into your very being to become a true living siege weapon.

Bonus Proficiencies

3rd-level Bastion Breaker feature

You gain proficiency with smith’s tools, and you learn to speak, read, and write one language of your choice.

Advanced Protocols

3rd-level Bastion Breaker feature

You can use advanced protocols to enhance your gear and body. You learn two protocols of your choice, from among the protocols described below, and each time you gain a level in this class, you can replace one protocol you know with a different one from this feature. When you reach certain levels in this class, you learn additional protocols, as shown in the Protocols Known table.

Protocols Known

Whenever you finish a long rest, you can touch a number of objects equal to the number of protocols you know, and you instill a different protocol onto each of the objects. To be eligible, an object must be a weapon, a suit of armor, a shield, a piece of jewelry, or something else you can wear or hold in a hand. Your protocol remains on an object until you finish a long rest, and an object can bear only one of your protocols at a time.

The following protocols are available to you when you learn a protocol. If a protocol has a level requirement, you must be at least that level in this class to learn the protocol. If a protocol requires a saving throw, your Advanced Protocol save DC equals 8 + your proficiency bonus + your Constitution modifier.

Demolition Protocol (Cloud Rune). This protocol emulates the deceptive technology of advanced deception systems. While wearing or carrying an object inscribed with this protocol, you have advantage on Dexterity (Sleight of Hand) checks and Charisma (Deception) checks.

In addition, when you or a creature you can see within 30 feet of you is hit by an attack roll, you can use your reaction to invoke the protocol and choose a different creature within 30 feet of you, other than the attacker. The chosen creature becomes the target of the attack, using the same roll. This magic can transfer the attack’s effects regardless of the attack’s range. Once you invoke this protocol, you can’t do so again until you finish a short or long rest.

Explosive Ordinance Protocol (Fire Rune). While wearing or carrying an object enhanced with this protocol, you have advantage on DEX (Acrobatics) checks Dexterity saving throws to avoid area of effect damage.

In addition, when you hit a creature with an attack, you can activate the protocol's destructive force: the target takes an extra 2d6 force damage, and it must succeed on a Strength saving throw or be moved 30 feet away from you. Once you activate this protocol, you can’t do so again until you finish a short or long rest.

Demolition Protocol (Frost Rune). This protocol enhances your ability to breach the walls of your enemy's structures. While wearing or carrying an object enhanced with this protocol, you have advantage on Intelligence (Investigation) checks and Charisma (Intimidation) checks.

In addition, you can activate the protocol as a bonus action to help you break your enemy's bastions. For 1 minute, you deal double damage to structures and non-magical objects. Additionally, when you deal extra damage with your Breaker's Might feature, if the target is a structure or object, you deal an additional die of damage from that feature to that structure or object.

Improved Optics Protocol (Stone Rune). This protocol enhances your optics. While wearing or carrying an object enhanced with this protocol, you have advantage on Wisdom (Insight) checks, and you have darkvision out to a range of 120 feet.

In addition, when a creature you can see ends its turn within 30 feet of you, you can use your reaction to invoke the protocol and force the creature to make a Wisdom saving throw. Unless the save succeeds, the creature is charmed by you for 1 minute. While charmed in this way, the creature has a speed of 0 and is incapacitated, descending into a dreamy stupor. The creature repeats the saving throw at the end of each of its turns, ending the effect on a success. Once you invoke this protocol, you can’t do so again until you finish a short or long rest.

Fortified Exoskeleton Protocol (Hill Rune, 7th Level or Higher). This Protocol bestows an advanced exoskeleton system.  Wearing or carrying an object enhanced by this Protocol gives you resistance to fire damage.

In addition, you can activate the Protocol as a bonus action, gaining resistance to bludgeoning, piercing, and slashing damage for 1 minute. Once you activate this Protocol, you can’t do so again until you finish a short or long rest.

Temporal Predictor Protocol (Storm Rune, 7th Level or Higher). Using this protocol, you can glimpse the future with advanced temporal prediction systems. While wearing or carrying an object enhanced with this protocol, you have advantage on Intelligence (Arcana) checks, and you can’t be surprised as long as you aren’t incapacitated.

In addition, you can activate the protocol as a bonus action to enter a prophetic state for 1 minute or until you’re incapacitated. Until the state ends, when you or another creature you can see within 60 feet of you makes an attack roll, a saving throw, or an ability check, you can use your reaction to cause the roll to have advantage or disadvantage. Once you activate the protocol, you can’t do so again until you finish a short or long rest.

Demolition Protocol (Frost Rune)

This protocol enhances your ability to breach the walls of your enemy's structures. While wearing or carrying an object enhanced with this protocol, you have advantage on Intelligence (Investigation) checks and Charisma (Intimidation) checks.

Additionally, when you deal extra damage with your Breaker's Might feature, if the target is a structure or object, you deal an additional die of damage from that feature to that structure or object.

Displacement Protocol (Cloud Rune)

This protocol emulates the deceptive technology of advanced deception systems. While wearing or carrying an object inscribed with this rune, you have advantage on Dexterity (Sleight of Hand) checks and Charisma (Deception) checks.
