In this sourcebook, environmental hazard🧸s can take the form of Supernatural Regions, Magical Phenomena, or even Natural Hazards. All of these can be great for your campaign, but we've compiled the list below of🐲 the best for your table.

The first of these envi🐻ronmental hazards is a Supernatural Region that assumes that an entire space is 'haunted.' This can include decrepit manors or haunted forests. For Supernatural Regions, once a player enters the space, you can set a handful of triggers (such as casting a spell) to then subsequently roll on a random effect table.

For the Haunted environment, Tasha's suggests triggers such as gaining the frightened condition, darkness, or the chime of midnight. Effects can include violent thunderstorms, resurrection 168澳洲幸运5开奖网:of undead creatures, or strange wisps of vapor appear൩ing in the air꧃ around the players.

9 Mirror 𝔉Zone

It's Just Your Reflection

Don't be afraid of a little vanity. In Tasha's Cauldron of Everything, Mirror Zones occur when extraplanar magical entities converge with reflections. If players have entered a mirror zon🐎e, the trigger effects can include the shattering of a mirror or the use of teleportation and illusion magic.

From there, Mirror Zone effects can include things like the explosion of a Hallucinatory Terrain spell, a creature gaining the benefits of the Blink spell, or the appearance of enemy mirror shards th🐭at attack players. You can always use the effects table found in Tasha's, or you can make your own effects depending on the flavor of your campaign!

8 🦄 Eldritch Storm

Magical zones throughout the world of Dungeons & Dragons can make regular storms take on an Eꩲldritch, arcane quality to them. There are a handful of different types of Eldritch storms, including Flaywinds (extra strong winds), a Flame Storm, or even a Necrotic Tempest.

Each of these storms has its own magical effects. These are all great 168澳洲幸运5开奖网:for nautical campaigns where players must brave stormy seas. The most in🐻teresting of these storms is known as Thrym's Howl, which creates icy wind that imparts cold damage and reduces players' ability to heal.

7 🍌 Unearthly Roads

Take Me Home

The magic of the weave is everywhere in the world, and sometimes, this effect even creates magical roads between realms. When these Unearthly Roads occur, they all♒ow players and characters to travel great distances in a matter of minutes.

Whenever a player discovers an Unearthly Road between two planes of existence, or two spots on the same plane of existence, they can travel 21 miles in the time it would take them to travel one normally. Typically, these Uneartlhy Roads require a specific key or item to unlock, and can't just be♐ accessed by anyone.

6 ♍ Avalanches

Avalanches are a great way to keep yo💛ur party on their toes when traversing a snowy mountainsid🍌e. Per the rules in Tasha's, a normal avalanche is about 300 feet wide, 150 feet long, and 30 feet thick. This can prove devastating for low-level parties, so use this effect sparingly.

However, you can use an avalanche 168澳洲幸运5开奖网:for a high-level party relatively easily. You'll have players roll initiative to avoid or defend themselves from the avalanche. Twice per round, on initiati🔥ve count ten and zero, the avalanche moves 300 feet. Anyone caught up in the avalanche is blinded and restrained and gains a level of exhaustion for every five minutes buried.

5 Infested

Not For The Faint Of Heart

Sometimes, if under the thumb of💮 giant arachnids or insects, an entire metropolitan populace can suddenly become infested. This environmental hazard is great for long-term campaign arcs, in which players must free a large🐈 populace from the thumb of a horde of creatures.

Runningཧ out of traps and puzzles to throw at your expert D&D players? Try🍷 using these environmental effects instead.

This is a Supernatural Region, meaning when players enter the space, they can trigger various effects by either taking a short or long𒐪 rest in the area, disturbing nests or webs, or anyone attacks a creature in the horde. Effects can include random encounters with the ൲creatures, bioluminescence, or the appearance of additional webbing, forcing players to move as though they are in difficult terrain.

4 🐬 Psychic Resonance ✱

Did You Just...Speak?

Som﷽etimes, in the world of Dungeons & Dragons, players can enter a space or realm in which strange psychic limerences occur. This can create forced telepathy, or allow certain creatures that know no lan♒guages to suddenly be able to speak. This means that even normal, non-magical beasts can potentially communicate with players in these zones.

Triggers for these realms can include creatures becoming charmed or frightened, or when a character encounters a powerful emotional experience. Other effects of Psychic Resonance zones can include increases to Intelligence 🐠checks or the inability to take a long rest.

3 ꦏ Unraveling Magic 🗹

Wild Magic, But Worse

You've heard of a Wild Magic sorcerer, but what about a Wild Magic zone? Unraveling Magic zones are areas in which the source of magic is corrupted or otherwise damaged. This can cause strange, unpredictable effects in sp🌊ellcasting. Triggers for this supernatural zone can include charges spent on a magic item, any spell cast at first level or higher, or when a magical creature dies.

Effects that come after the trigger are vast and varied. You can either use the table presented in Tasha's Cauldron of Ever♛ything to determine what happens in the zone, or you can even decide to use the Wild Magic Table from the 2024 Player's Handbook instead.

2 💦 Mimic Colonies ও

Tasha's Cauldron of Everything has stat blocks and comওbat info for running a mob encounter with mimics.

1 Flood

Lastly, Tasha's Cauldron of Everything also has a ton of varying natural hazards you can use by mimicking the effects of cer✱tain spells. One such example is a flood, which can prove really fun for use in both natural🥂 settings and urban-sprawl campaigns.

When using a flood, you can mimic the rules of a Control Water or Tsunami spell (Tsunami is more apt). Once you learn how to use spells in this way to run environmental hazards, you can use any number of spells to homebrew unique effects for yoursel𓆉f!
