2nd-level Circle of Rust feature
Druids of the Circle of Rust have accepted that nature in the Ashen Veil is no longer green and growing. Instead, they venerate the beauty of decay, the resilience of rust, and the strange ecosystems that have emerged in the post-Unveiling world. They commune with corrupted beasts, metal-eating fungi, and the twisted flora that grows in irradiated wastelands.
Circle Spells
Your mystical connection to rust and decay grants you access to certain spells. At 2nd level, you learn the poison spray cantrip. At 3rd, 5th, 7th, and 9th level you gain access to the spells listed for that level in the Circle of Rust Spells table.
Once you gain access to one of these spells, you always have it prepared, and it doesn't count against the number of spells you can prepare each day. If you gain access to a spell that doesn't appear on the druid spell list, the spell is nonetheless a druid spell for you.
| Druid Level | Circle Spells |
|---|---|
| 2nd | poison spray (cantrip) |
| 3rd | ray of sickness, grease |
| 5th | heat metal, acid arrow |
| 7th | stinking cloud, protection from energy |
| 9th | blight, vitriolic sphere |
Rusted Hide
At 2nd level, your skin takes on a faint metallic sheen, granting you natural armor. When you aren't wearing armor, your AC equals 13 + your Dexterity modifier. You can use a shield and still gain this benefit.
Additionally, you have resistance to poison damage and advantage on saving throws against being poisoned.
Corroded Wild Shape
At 2nd level, when you use your Wild Shape, the beast form you assume has a rusted, corroded, or toxic appearance (rust-colored fur, exposed metal bones, dripping with acid, etc.). While in this form, you gain the following benefits:
- Your natural attacks deal an additional 1d4 acid or poison damage (your choice when you Wild Shape).
- You can breathe normally in toxic environments.
- You are immune to disease.
The additional damage increases to 1d6 at 6th level, 1d8 at 10th level, and 1d10 at 14th level.
Decay Aura
At 6th level, you can exude an aura of corrosion. As a bonus action, you activate an aura in a 10-foot radius around you. The aura lasts for 1 minute, until you dismiss it (no action required), or until you're incapacitated.
While the aura is active:
- Nonmagical objects made of metal in the aura corrode. A weapon takes a permanent −1 penalty to damage rolls, and armor takes a permanent −1 penalty to AC. If the penalty reaches −5, the item is destroyed.
- Creatures hostile to you that start their turn in the aura take acid damage equal to your Wisdom modifier.
You can use this feature a number of times equal to your Wisdom modifier (minimum of once), and you regain all expended uses when you finish a long rest.
Toxic Resilience
At 10th level, you become immune to poison damage and the poisoned condition. Additionally, when you're subjected to acid damage, you can use your reaction to gain immunity to acid damage until the end of your next turn.
Master of Decay
At 14th level, you've fully embraced the beauty of entropy. You gain the following benefits:
- You can cast blight at will, without expending a spell slot.
- When you use your Wild Shape, you can choose to transform into an ooze instead of a beast (use ooze stat blocks of appropriate CR). You retain your Corroded Wild Shape benefits.
- Your Decay Aura radius increases to 20 feet, and metal objects corrode twice as fast (−2 penalty per exposure instead of −1).
