Microlite20 ATMO

Aew pessoal! Hoje vou postar a versão 1.0 do Microlite20 adaptado por mim. Qualquer pergunta ou sugestão é só me dizer! zephos2@gmail.com


There are 4 stats : Strength (STR), Dexterity (DEX), Mind (MIND) and Charisma(CHA).
Roll 4d6, drop lowest dice. Total remaining 3 dice and allocate to one of the stats. Repeat for remaining stats.
Stat bonus = (STAT-10)/2, round down.


Numan get +1 to all skill rolls
Elren get +2 CHA
Darven get +2 STR
Bastet get +2 DEX


Fighters wear any kind of armour and use shields. They have a +3 bonus to Physical and add +1 to all attack and damage rolls. This increases by +1 at 5th level and every five levels on.
Rogues can use light armour. They have a +3 bonus to Subterfuge. If they successfully Sneak (usually sub+DEX, but depends on situation) up on a foe they can add their Subterfuge skill rank to the damage of their first attack.
Mages can wear light or medium armour. They can cast arcane spells, and gain a +3 bonus to Knowledge.

There are just 4 skills : Physical, Subterfuge, Knowledge and Communication. Roll higher than the given Difficulty Class to succeed.
Each character starts with 1 point in each skill, and gets 4 points to distribute as they wish into the skills, with a maximum of 3 points in each skill.
Skill rank = your level + any bonus due to your class or race.
Skill roll = d20 + skill rank + whatever stat bonus is most applicable to the use + situation modifiers
For example, Climbing would use Physical + STR bonus. Dodging a falling rock is Physical + DEX bonus. Finding a trap is Subterfuge + MIND bonus. Disabling a trap is Subterfuge + DEX bonus.
Note that there are no “saving throws” in this game; use Physical + STR or DEX bonus for Fortitude and Reflex saves. Saving against magic (Will save) is usually MIND bonus + your level.

Alternative Magic

This magic system is based on 4×4 Magic from the Microlite20 website. All spells are cast by combining two Words of Power, one from the Actions and one from the Spheres, and making a successful Magic Attack (Level+MIND) against SR of the opponent. Human-sized inanimate objects have a SR of 10, which can vary by size, mass, or other factor.
A spell’s Level determines the extent of its effect and its impact on the caster. A 1st Level Spell has 1d6 (HP, 10′, etc.) extent of impact. Add an additional d6 per level. Making an effect permanent adds 25 to the SR. A spell causes (1 + 2 x Spell Level) HP damage to the caster, which is recovered only through 8 hours of rest. They can learn an additional Action word or gain a +5 bonus to a Word they already know at every 4th level.
Spells that affect inanimate objects are generally permanent; an enlarged pebble will stay large, a broken belt will stay mended. Magically created fires, etc, will die down naturally. Living creatures will eventually revert back to their normal form, though any healed damage stays healed.
The Actions
Alter – Alter spells can turn your target into a particular type of creature or substance.
Charm – Charm spells alter the moods and emotions of creatures, making them more likely to perform certain actions. Charm spells cannot force a character to perform more than the most primitive actions; at best, a Charm spell might put a creature to sleep or make it attack in a frenzied anger.
Defense – Defense spells enhance your Armor Class or saving throws, or grant energy resistance or damage reduction. Some Defense spells can restrict the movements of certain types of creatures.
Evoke – Evoke spells cause elemental or alignment-based damage, and may have other detrimental and damaging effects.
Heal – Heal spells cure damage and other afflictions to creatures or objects with the appropriate element or alignment type.
Illusion – Illusion spells deceive the senses or minds of others. Illusions have no real effect, but they can mislead creatures and cause them to take dangerous courses of action.
Infuse – Infuse spells fill creatures or objects with spiritual or elemental energy, enhancing attributes that are related to the chosen element, or making the target detect as the chosen alignment or element.
Move – Move spells enhance movement abilities, allowing creatures to swim, burrow, fly, travel at great speeds, even teleport or travel across dimensions.
Summon – Summon spells can bring creatures to you from elsewhere (such as the classic demon summoning), create a creature out of existing material (like turning bones into a skeletal warrior), or can create a creature whole cloth (like making a construct out of ectoplasm).
The Spheres
Life, Death, Fire, Water, Earth, Wind, Light, Dark, Ice, Lightning, Crystal, Metal.


Hit Points = STR Stat + 1d6/Level. If HP reach 0, unconscious and near death. Further damage directly reduces STR. If that reaches 0, death.

Roll d20 + DEX bonus for initiative order. Everyone can do one thing each turn; move, attack, cast a spell, etc.

Melee attack bonus = STR bonus + Level
Missile attack bonus = DEX bonus + Level
Magic attack bonus = MIND bonus + Level

Add attack bonus to d20 roll. If higher than your opponent’s Armour Class (AC), it’s a hit. Natural 20 is automatically a critical doing maximum damage.

Fighters and Rogues can use DEX bonus + Level as Melee attack bonus instead if wielding a light weapon. Fighters and Rogues can wield 2 light weapons and attack with both in a round if they take a -2 penalty on all attack rolls that round. Rapiers count as light weapons, but you cannot wield two rapiers at the same time.

Weapons define how many attacks a character can do. All attacks have the same attack bonus.

Add STR bonus to Melee damage, x2 for 2-handed weapons.
Armour Class (AC) = 10 + DEX bonus + Armour bonus.

Other Hazards

Falling : 1d6 damage per 10′, half damage on Phys+DEX save. DC=depth fallen in feet
Spikes : add +1 point to falling damage per 10′ fallen, max +10
Poison : Phys+STR save to avoid or for half, depending on poison. Effect varies with poison type.
Extreme Heat & Cold : If not wearing suitable protection, Phys+STR save once every 10 minutes (DC 15, +1 per previous check), taking 1d6 damage on each failed save.

Level Advancement

Encounter Level = Hit Dice of defeated monsters, or the given EL for the trap, situation, etc. Add +1 for each doubling of the number of foes. eg: 1 kobold = EL1. 2 kobolds = EL2. 4 kobolds = EL3, etc.

Add up the Encounter Levels (ELs) of every encounter you take part in. When the total = 10 x your current level, you’ve advanced to the next level. Reset the total to 0 after advancing.

Each level adds:
+1d6 to Hit Points
+1 to all attack rolls
+1 to your primary skill(s)
+1 to secondary skills every even level (2, 4, 6, etc.)
+1 to STR, DEX, MIND or CHA every third level (3, 6, 9, 12, etc.)

Fighters gain +1 to their attack and damage rolls at levels 5,10,15,etc. Magi gain access to new spell levels at levels 3,5,7,9,etc.
The 1st level adventurers have just completed a dungeon adventure, and defeated 5 EL1 encounters, an EL2 trap and the EL3 leader. That’s a total of EL10, so they all advance to level 2. They need to defeat another 20 Encounter Levels to reach Level 3.

Game Master’s Guide
Diseases have various symptoms and are spread through a number of ways. Several typical diseases are summarized below.
The entries for diseases include the following information:
Name of the disease: Type, DC, incubation, damage.
Type lists the disease’s method of delivery (contact, inhaled, or injury).
DC lists the phys+STR check DC needed to prevent infec¬tion.
Incubation lists the time before damage begins.
Damage lists the ability damage the character takes after incubation and each day afterward.
Cackle Fever: Inhaled, DC 16, 1 day, –1d6 MIND.

Extreme Heat & Cold
If not wearing suitable protection, a character must make a Phys+STR check once every 10 minutes (DC 15, +1 per previous check), taking 1d6 damage on each failed save.
Falling Damage
A falling character takes 1d6 hp of damage per 10 feet fallen. If the character makes a successful Phys+DEX roll, he takes only half damage. The DC for the phys+DEX roll is equal to the depth fallen in feet.
In the event that the fall ends in an area laden with spikes or jagged rocks, add +1 hp of damage to falling damage per 10’ fallen (with a maximum of +10 hp).
Characters can possibly take damage from a weapon that has been poisoned, be attacked by a creature whose natural attacks feature poison, consume poison hidden in food or drink, or be poisoned in some other way.
Several typical poisons are summarized below. The entries for poisons include the following information:
Name of the poison: Type, DC, damage, price.
Type lists the poison’s method of delivery (contact, ingested, inhaled, or injury).
DC lists the phys+STR check DC needed to avoid the poison’s damage.
Damage is expressed as “xdx/xdx.” The first number is the initial damage, taken immediately upon failing the phys+STR check against the poison. The second number is the secondary damage, taken one minute after exposure to the poison if a second phys+STR check is failed. Ability damage is tempo¬rary unless marked with an asterisk(*), in which case the loss is permanent. Unconsciousness lasts 1d3 hours.
Price lists the cost for one dose of the poison. It can usually only be obtained through less-than-reputable sources, as the possession of poisons are commomly illegal.

Whether inside a dungeon or a nobleman’s manor house, adventurers can often be hurt, or even killed, without ever

Type lists the trap used and the effect it has.
