Languages. If the half-dragon knows languages, it speaks Draconic in addition to the ones it knows.

Senses. The half-dragon gains blindsight out to a distance of 10 feet and darkvision out to a distance of 60 feet.

Resistances. The half-dragon gains resistance to a damage type dealt by the breath weapon of its dragon half.

Breath Weapon. The half-dragon uses the Breath Weapon attack of the oldest dragon of its type that has a Challenge Rating equal to or lower than the half-dragon’s Challenge Rating (minimum wyrmling).

Wings. If the half-dragon’s Challenge Rating is 9 or higher, it gains wings and a fly speed of 60.

This page provides tips for running journeys.

Suggested Penalties

The outcome of an exploration challenge is decided by the Narrator. On failure of an exploration challenge, there are suggested outcomes in the challenge stat block, but also consider the following penalties.

• Fatigue and/or strife
• Supply loss
• Damage
• Hit dice expenditure
• Equipment damage
• Diseases
• Mental stress effects
• Time loss
• Unusual penalties (see below)

Penalties can be instantaneous, permanent, until the next long rest, or until the next haven .

Exploration Challenge Damage

If a challenge inflicts damage as a penalty, the following values are suggested. Damage is doubled on a critical failure.

A trap is designed to inflict damage directly. An obstacle inflicts less damage but may also incur Supply loss or other effects.

Note that damage is recovered during a long rest, so unless a combat encounter is anticipated before the next long rest, damage has less practical effect as a challenge penalty.

Unusual Penalties

• Aging +/- 1d6 years (permanent)
• A stink or odor which inflicts disadvantage on Charisma checks until you reach a haven
• Other conditions , such as rattled or poisoned until the next long rest
• Inability to consume or benefit from Supply until you reach a haven
• A magical mutation of some kind
• Nightmares which prevent benefiting from a long rest until you reach a haven
• Loss of voice (which can affect spellcasting)

When making a journey , follow these steps.

1. Based on the world map, the Narrator determines which Regions exist on the route.
2. For each Region determine the travel distance, travel pace, and resultant travel time.
   1. The Narrator determines the Region’s traits and task DC, and rolls 1d20 to determine the prevailing weather.
   2. Each adventurer selects one or more journey activities and makes relevant checks.
   3. The Narrator rolls for one or more encounters using the appropriate tiered table for that Region . These may be monsters, exploration challenges, social encounters, or scenery.
   4. Determine Supply usage and apply [conditions|fatigue] if necessary.
3. Repeat step 2 for each Region .
4. Arrive at your destination!

The order in which journey activities are resolved and when encounters take place is up to the Narrator, although we suggest that you resolve journey activities, and then run any encounters.
