Dryads

Dryads are a caste based species introduced in the Ideology DLC. Each dryad is subservient to a dryad queen that lives symbiotically with a Gauranlen tree. Colonist are able to exploit this subservience and symbioticity by connecting with the tree itself, granting partial control of the dryads it produces for a colony's benefit.

Barkskin dryad 

A dryad caste specialized in absorbing hits during combat. Barkskin dryads are covered by a thick bark-like hide which is partly formed by the Gauranlen tree itself. Under human influence, it can act as a damage-absorbing fighter.
In general, dryads are mammal-like creatures that have a symbiotic relationship with the Gauranlen tree. They reproduce together with their tree, which contains a hidden dryad queen. Dryads can morph into various specialized castes.

Berrymaker dryad 

A dryad caste specialized in food production. Together with its Gauranlen tree, this dryad can generate nourishing berries on an ongoing basis. However, it is slow and ineffective at work or combat.

Carrier dryad 

A dryad caste specialized in carrying items. Under human influence, it can help haul things where they need to go.
In general, dryads are mammal-like creatures that have a symbiotic relationship with the Gauranlen tree. They reproduce together with their tree, which contains a hidden dryad queen. Dryads can morph into various specialized castes.

Clawer dryad 

A dryad caste with huge claws that is specialized in aggression and damage-dealing attacks. Though it can do tremendous damage, it is vulnerable to attacks itself.
In general, dryads are mammal-like creatures that have a symbiotic relationship with the Gauranlen tree. They reproduce together with their tree, which contains a hidden dryad queen. Dryads can morph into various specialized castes.

Gaumaker dryad 

A dryad caste with the unique ability to produce new Gauranlen pods and reproduce the Gauranlen tree along with its symbiote, the dryad queen. To do this, three gaumaker dryads must slowly merge.

Immature dryad 

Dryads are small mammalian creatures that have a symbiotic relationship with the Gauranlen tree. This immature dryad can support and protect its tree, but its main purpose is to morph into more specialized and powerful dryad forms.

Medicinemaker dryad 

A dryad caste specialized in medicine production. Together with its Gauranlen tree, this dryad can generate medicinal herbs on an ongoing basis. However, it is slow and ineffective at work or combat.

Woodmaker dryad 

A slow, bumbling caste of dryad which specializes in wood production. Together with its Gauranlen tree, this dryad can generate a wood-like material on an ongoing basis. However, it is slow and ineffective at work or combat.

Summary

All dryads are produced by a Gauranlen tree. They have no need to eat, are immune to disease events, and have a 100% Toxic Resistance, rendering them immune to Toxic fallout and Toxic buildup. Dryads will bleed, but cannot bleed to death. They have a sleep need requirement and tend to sleep at nighttime, not maintaining a normal sleep schedule.

Dryads heal abnormally fast, and can be commanded anywhere to enter a healing cocoon, which will heal all present injuries (not including lost limbs). Alternatively, they can retreat to a gauranlen tree. This takes 3 days and heals all permanent injuries, lost parts, and bad conditions.

Dryads will automatically have the Animals training for their respective caste. The barkskin and clawer dryads start with Guard and Attack, the carrier starts with Haul, and the rest have no trainability. They can only have their Gauranlen tree's connected pawn as their master, but can form bonds with their master tends to them. They do not require regular handling to maintain tameness or other skills.

All dryad castes have a meat yield of 3 immature dryad meat, despite being mature. Immature dryads give 4 meat.

Dryad spawning

All castes will start off as an immature dryad. Immature dryads will spawn every 6 days, according to an invisible timer. If there are empty dryad slots, this timer will be visible; it'll still tick down if there aren't empty dryad slots, waiting for an opening.

Immature dryads will attempt to immediately form into a cocoon upon spawning, as long as their sleep need is met. It takes 5 days for them to grow into a caste. Players can choose the caste for each specific tree, which future dryads will be. Changing a tree's caste will cause all dryads to become immature again, instead taking 5^[Verify] days to grow up.

An unconnected tree will produce up to two immature dryads, which can immediately enter cocoons upon the tree gaining a connection.

Behavior

Dryads cannot be assigned to any areas. While not hauling or following a drafted pawn, dryads will meander nearby their Gauranlen tree. They will attempt to put out fires on Gauranlen moss nearby. When following a drafted pawn, dryads perform identically to other animals.

Upon releasing a dryad to the wild, absolutely nothing will change, they remain connected to the tree and maintain their behavior. They cannot be re-tamed and your pawns will lose control of them.

Gauranlen tree connection interaction

See also: Gauranlen tree

If there are more dryads than the "mother" tree can support (i.e. by going under the minimum connection limit to support a number of dryads) the dryad will "return" to the Gauranlen tree. A dryad returning to the tree will not have any effect on the spawn timer.

Analysis

All dryads have a specialized purpose. Berrymaker, medicinemaker, and woodmaker dryads all create resources that may be difficult, depending on biome and Ideoligion. Barkskin and clawer dryads fight, carrier dryads haul, and gaumaker dryadss can create more trees and thus more dryads.

Tree pruning is a time consuming process - colonists connected to trees will need to dedicate all their time managing their trees. For the three resource -makers, just planting crops (when possible) tends to give more yield per work. Haulers are more efficient than humans haulers, as 1 tree and 1 colonist will support 4 haulers who don't need to eat or recreate, and will work longer than prune time. Combat dryads are weak on their own, but have unique advantages and dedicated combat roles - see #Combat potential for details.

Economic potential

There are 3 dryads that offer creating items of value, the woodmaker, medicinemaker, and berrymakers. All three will create resources once every 2 days.

• Berrymaker dryads produce  38.2 of raw berries in Market Value.
  • Selling raw is most efficient, as packaged survival meals or pemmican require meat to craft.
• Woodmaker dryads produce  30 of wood in Market Value.
  • Wood can be fashioned into sculptures, valued based on Art skill. However, one harvest is not enough for a sculpture, and they take a noticeable amount of work. See Sculpture Production for more details.
  • Converting wood to chemfuel is a net loss ($2.4 wood makes $2.3 worth of chemfuel), but is 16x lighter.
• Medicinemaker dryads produce  30 of herbal medicine in Market Value.
  • It's best to sell raw - industrial medicine, their only product, isn't profitable as it requires buying neutroamine.

Therefore, berrymaker dryads are the most efficient money dryad, giving the most value for no extra work. However, berries expire after 14 days, which may necessitate woodmaker dryads instead.

Berrymakers create $11.46 (at 0 Trade Price Improvement) per day, per dryad. If you are pruning 2 trees with a 20 plant-skill colonist, they can support 8 dryads (working 11 hours a day), and thus make ~$8.33 per hour of work, plus transportation. To maintain at least one dryad, ~2.5 hours of work is needed per day, so more dryads per tree are more efficient than more trees.

For comparison, planting a single psychoid plant gives $28 in flake. Corn can be planted and harvested to make $605 per hour with the right bionics. This makes dryads a fairly poor method of making money, and more useful for their situational or Ideoligion benefits.

Combat potential

Only Barkskin and Clawer dryads are capable of offensive combat. Either dryad can follow their tree's connected pawn into battle like a trained animal. Dryads have special advantages over normal animals: they can't die of blood loss (so don't need to be tended to immediately), can heal otherwise permanent injuries in 3 days, and do not contribute towards colony wealth (making raids smaller). However, they can't be brought away from colony normally via caravan or pod launchers. Other dryads (domestic or wild/unconnected) will attack when provoked, but have poor combat statistics. All dryads are small in size, and will be hit far less frequently.

Dryads are good at fulfilling their role of supporting colonists and other pawns in combat:

• Barkskin dryads boast high defense, with similar armor to a thrumbo (70% sharp, 40% blunt). They can take roughly 3-4 shots from most firearms. With 3.16 DPS, they are fairly weak at damage, but their armor and aforementioned healing make them useful. With such high armor, these dryads are good at distracting enemies while your colonists fire from afar. Alone, they are roughly equal to dogs in combat.
• Clawer dryads have highest melee DPS of any non-human or ghoul in the game, and out-damaging scythers and thrumbos and offering over double the AP, and their first striking stunning for a short duration. The opposite of barkskins, clawers have poor durability. This makes them strong when combined with other melee attackers (including other clawers), in a cramped hallway, or when facing a small number of powerful enemies like centipedes or thrumbos. Alone, they are typically capable of beating gun-wielding human pawns.

Conclusion: Even though they require a large amount of a pawn's time, dryads don't need food or training. With strong healing and immunity to blood loss, players may find them easier to keep than other pets. If they die, the tree-connected pawn only receives a -2 mood debuff, and a new dryad can take their place in 5-12 days.

Trivia

• Immature dryads still appear as adults on the animals tab.
• When entering cocoons, the dryads will maintain the appearance of their previous caste.
• If a tree with dryads has its connection to the connector severed, such as by kidnapping or death, all specialized dryads revert back to immature dryads.
• Dryads can be taken off of the map when choosing animals to take with you when starting a new colony after obtaining a piece of the archotech map, and a master that is taken with them remains as their master. Dryads function without their gauranlen tree if taken off the map in this way, but despawn after a period of about a little longer than a season.
