Power Mechs

Power Mechs

Power mechs are immune to poison, psychic, and necrotic damage and are immune to the
poison effect. However if the pilot is able to be targeted by attacks that do these types of
damage they can be dealt directly to the pilot.

-Mech skeletons(Skells)-

Mech skeletons(Skell for short) are the frames to which upgrades can be applied.

-Mech Stats-

All mechs have an Intelligence and Charisma of 1 and a Wisdom of 10. Strength, Dexterity, and
constitution are determined by Skell type to create. Mech armor class is equal to
12+Constitution+(Mech or pilot dexterity,whichever is higher)
Mech suits grant the pilot total cover, however the glass at the front of the cockpit is clear and
can be broken if it takes a quarter of the max hp of the mech.

Mech HP=Tech level*CON*10 cannot be less than 30.
Mech speed= dex*5+20(min 15)

-Power-

Mech power sources in my world are from crystals known as gaea crystals condensed and
stored as batteries. A single mech battery has enough power for a half hour and costs about 25
gp. Most mechs have two battery slots though some have more.batteries tend to be on the back
of the mech and individually have 20 hp. And remember if your mech battery dies it's difficult to
carry meaning you can't go back where you came from.

Optional- recharging batteries.

If you are proficient in mechs you can expend a level 2 spell slot or higher over a short or long
rest to recharge a battery.(the spell slot is expended after the short rest warlocks still lose the
spell slot like everyone else.)

-Making checks-

Checks in mechs can be done in two ways pilot checks and mech checks. These still use the
standard abbreviations. However before a check it will Have a P or M. P for Pilot and M for
mech. As such MDex would be mech dexterity And PInt would be Pilot intelligence.

-Upgrades-

-Technology levels-

.all mechs have a Technology-Level this Technology-Level effects what types of upgrades can
be applied. Tech-levels range from 1-4. You can equip any upgrades to your mech as long as its
tech level is equal to or higher than the upgrades level.
Much tech levels effect size. Tech level 1 mechs are usually large. Tech level 2 can be large or
huge. Anything larger than tech level 2 is huge or larger.
Tech levels 1-2 tend to be relatively simple while 3-4 are much more complicated. Tech level 4
machines are very expensive and tend to be owned only by the richest.

-Technology slots-

Technology slots affect how many technologies may be equipped. To apply an upgrade you
must have enough slots to accommodate it. An upgrade can require multiple slots. Tech slots on
a mech are equal to tech level*3

-Adding tech-

To add a piece of tech you must expend time equal to (2*slots*level) hours as well as have the
gold to add it plus you must have achieved any other prerequisites.

-Removing tech-

Removing a piece of tech costs half as much time and money as adding it.

-Mech pieces-

Finally certain upgrades are limited as to where where you can equip them. Different body parts
may have upgrade limitations

-Limbs-

Limbs have 3 categories arms, legs, and general. An upgrade can specify arm or leg however
generaal limbs may equip arm and leg upgrades At maximum you can apply two upgrades to
each limb. Limbs may be used as a 2D6+Str bludgeoning weapon.
‘

-Torso-

The body of the mech, The torso can hold a number of upgrades equal to the tech level. The
toro is likely where the controllers compartment is.

-Head-

The head of the mech, often where important sensory parts are held. Some mechs do not have
heads while others are merged with the body this will be marked as (head-fused).mech heads
can hold 1 upgrade.
Some mechs have an open cockpit instead of a head. In this case the pilot sits in the open at
the top of the much where the head would be.

mechanical}) with the mech. You basically become the
mech because of this only the best of both come
through. While in the mech all stats are equal to the
higher of you or the mech’s. However once installing
biologic connection a mech can only be piloted by a
single user.

The mech gains a force cannon which fires in a 120
by five foot line. All creatures within the line must
succeed on a dex save equal to the 10+PINT or take
10d8+(mech dexterity) damage. The cannon is fired
as a special action and can only be recharged on a

Fire 6 bolts as a special action, that lock onto a target,
each bolt deals 2d6 force damage. The target must
succeed on dexterity check equal to 10 plus Pint. If
they succeed on this save they must make the save
again once per turn for thirty seconds. If they fail a
save 1d6 of the bolts impact, for the sake of a damage
threshold the bolts count as a single attack. This
continues until all bolts impact or until thirty seconds
pass.

AC while flying. Charge attack, when you take the
dash action you may choose to charge the enemy, if
you do so you must make a to hit roll with

disadvantage but mech dexterity and pilot intelligence
to the roll.. The damage dealt to the opponent is equal
to your movement speed(dashing)*1d4 bludgeoning
damage however you take ¼ of the damage dealt by
the attack to your own mech. This damage is cut in
half if your mech has armor plating or a shield.

-Pilots-

Mech pilots must be at least 1 size smaller than the mech itself. A mech pilot must be proficient
in mech usage to use a mech. If the pilot is not proficient the difficulty class of any checks in the
mech are raised by 1 and every turn in combat the pilot must succeed on an intelligence check
DC 15.

-Mech pilot feat-

In addition to having pilots in the world a character may take the mech pilot feat(if feats are
available) Characters with this feat increase one stat by 1 to a maximum of 20. And gain
proficiency with mechs.

-Mech cost.

To determine the cost of a mech each part of it costs a certain amount of gold. The gold cost
multiplied by the tech level gives the actual cost of that part. Any health on a mech can be
determined by size. Anything that is the size of large must have less than 90 health points.
Huge mechs can have up to 250. Anything larger than huge uses up double the power and can
have any amount of health. To determine the gold cost of health you take the health multiply it
by the mech level and multiply it by 20. For example a tech level 4 250 health mech would have
a health cost of 8,000 gp.

Limbs-1500 gp per limb

Torso-4000 gp

Head-500 gp

Tech slot-150 gp

With all this a 250 HP huge tech level 4 humanoid mech with 16 tech slots would cost.
8000+6000(4)+16000+2000+600(16)=57,600 gp.

And a 30 HP tech level 1 humanoid mech with 1 slot would cost.
600+1500(4)+4000+500+150=9,450

-Mech Weapons-

Mechs can carry weapons and other objects with their arms which have hands. THis means that
you can have a weapon outside of the integrated ones for fluidity. Any weapons wielded by a
mech deal damage equal to that same weapon in human form multiplied by (tech level)*2. And
cost GP equal to that same weapon in human form multiplied by (tech level)*2. Rules affecting
mounted weapons are not affected by mechs not having mounts.

-Building a mech-

Building a mech falls under the downtime rules of artisans craft, however, you may have up to
50 people working on building an individual mech at once. Also the pricing system of the mechs
i've described is the retail price. The cost of building a mech is actually 3 quarters of the retail
price. This means the 57,600 gp mech is actually built at a cost of 43,200

-Mech types-

This section is the general rundown of mech types in my world, this is designed as a guide and
can be renamed to your decision. (Note: this only reflects how people refer to the mechs of the
world most mech frames are able to fit these roles with the correct upgrades though some do
better than others.

-Lancers-

Front line Combatants, lancers are a perfect mix of attack and defense allowing for mobility,
power, and protection all in one package.

-Cyphers-

Also known as zeros, Cypher mechs are quiet, low armor, but high attack power. Typically
lacking in the range department but they make up for that in the overwhelming melee power and
stealth granted by light armor and powerful strikes.

-Guardians-

Heavy defenders, Guardian mechs focus their attention on being in the enemy's face, taking
hits, and blocking them with their heavy armor. GUardian mechs are always protecting the
lighter units and granting them attack openings.

-SpellJammers-

Spell Jammers use modified mechs which allow them to cast spells using their mechs as a foci.
These mechs are unique and may sometimes fill in another roll of a different class on the
battlefield.

-Strikers-

And finally striker mechs. THese mechs focus on high ranged damage output, not very
defensive these mechs rely heavily on the guardians and lancers to protect them, But in return
they unleash powerful volleys of long ranged attacks, sometimes even ending a fight before it
begins.
