Green Mage Prestige Class

Prestige Class: Green Mage
The Green Mage is a spellcaster who channels the primal forces of nature to command the battlefield. Drawing power from the natural world—its plants, animals, and elements—they wield spells that hinder foes, empower allies, and reshape the terrain itself. A Green Mage is a guardian of balance, equally capable of nurturing life or unleashing nature's fury—especially through crippling debuffs that sap the strength of enemies and control the flow of battle.
Requirements

• To qualify for the Green Mage prestige class, a character must meet the following prerequisites:
• Proficiency in the Nature skill
• The ability to cast spells from the Druid spell list

• A demonstrated connection to nature, such as performing a sacred rite, healing a corrupted glade, or bonding with a nature spirit (DM’s discretion)

Class Features

• Hit Dice: d8 per Green Mage level
• Proficiencies: No additional armor or weapon proficiencies
• Spellcasting Ability: Wisdom
• Spellcasting Focus: You can use a druidic focus (e.g., sprig of mistletoe, carved wand, living vine) as your spellcasting focus for Green Mage spells.

At each level, you gain new spells known and spell slots as if you had gained a level in the Druid class.
Class Progression Note: If you entered this prestige class from a full spellcasting class (such as Cleric, Sorcerer, Wizard, etc.), you may choose to continue gaining class features from that class as you level in Green Mage. At each Green Mage level, you may either:

• Gain Green Mage features and spellcasting progression as listed, or
• Forego the Green Mage feature for that level and instead gain the class feature from your original spellcasting class (as if you had gained a level in that class). You still gain Green Mage spellcasting progression.

Level 3 – Nature’s Embrace: 
Your bond with nature fortifies your body and mind. While you are not wearing armor, your AC equals 10 + your Dexterity modifier + your Wisdom modifier. Additionally, you have advantage on saving throws against being restrained, petrified, or charmed by magical effects.
Debuff Boost: When a creature fails a saving throw against one of your spells that inflicts the restrained, blinded, poisoned, silenced, prone, frightened, or charmed condition, it suffers a penalty to attack rolls and saving throws until the end of your next turn. This penalty starts at -1 and increases to -2 at level 10, and -3 at level 18.
Buff Boost: When you cast a beneficial spell on an ally (such as a spell that heals, grants temporary hit points, increases AC, or removes a condition), they receive an additional bonus to attack rolls, saving throws, and ability checks equal to +1. This bonus increases to +2 at level 10 and +3 at level 18, and it lasts for 1 minute or until the spell's duration ends.
Haste Mastery: If you cast Haste on an ally, they do not suffer the lethargy penalty (no action or movement) when the spell ends.
Level 7 – Nature’s Bounty:
You can call upon the nurturing power of nature to restore vitality. Once per long rest, as an action, you create a 30-foot radius sphere of rejuvenating energy centered on yourself. All creatures of your choice within this area regain hit points equal to 2d8 + your Green Mage level + your Wisdom modifier. This healing increases to 3d8 at level 10, and 4d8 at level 15. Plants in the area bloom or flourish, and corrupted ground is momentarily cleansed.
Additional Effect: Any hostile creatures in the area must succeed on a Constitution saving throw or have their movement speed halved and suffer disadvantage on their next Strength or Dexterity saving throw.
Level 10 – Nature’s Wrath: 
The forces of nature bend to your will when lashing out. When you cast a spell that requires a creature to make a saving throw:

• The target has disadvantage on the saving throw if it is on natural terrain (such as grass, soil, stone, sand, or wood)
• Alternatively, if the spell deals acid, cold, fire, lightning, or poison damage, the target also has disadvantage, regardless of terrain

Additional Effect: If the target fails the saving throw, it becomes entangled by natural energy (vines, wind, frost, etc.) and its movement speed is reduced to 0 until the end of its next turn.
Constitution Disruption: When a creature fails a saving throw against one of your Green Mage spells, it suffers an additional -2 penalty to its next Constitution saving throw before the end of your next turn. This penalty stacks with other penalties imposed by your Green Mage features.
Nature’s Boon: Whenever you use Nature’s Wrath, you may also choose a number of creatures equal to your Wisdom modifier (minimum one) within 30 feet to receive Nature’s blessing. Each chosen ally gains temporary hit points equal to your Green Mage level and is affected by a Shield of Faith-like effect (+2 AC) for 1 minute. This blessing requires no concentration. You may use Nature’s Boon a number of times equal to your proficiency bonus, regaining all expended uses after a long rest.
Level 15 – Nature’s Shelter:
You can shape the land itself to shield your allies. As an action, you cause the terrain in a 20-foot radius centered on yourself to become overgrown and protective. This area is difficult terrain for enemies and grants half cover (+2 AC and Dexterity saving throws) to allies of your choice within the area.The effect lasts for 1 minute or until dismissed (bonus action). Once used, this feature can’t be used again until you finish a short or long rest.
Debilitating Terrain Effect: When an enemy creature enters the area for the first time on a turn or starts its turn there, it must succeed on a Strength saving throw or suffer the following effects:

• It is restrained, pulled prone, and grappled by thick vines and roots.
• While affected, its speed becomes 0.
• The creature is stunned until the end of its next turn.

The creature may attempt a Strength saving throw at the end of each of its turns to end the restrained, prone, and grappled conditions. The stun effect has no additional saving throw—if the initial Strength save is failed, the stun lasts until the end of its next turn.
Additional Debuff Aura: Enemies within the area must make a Wisdom saving throw at the start of their turn or have disadvantage on their next attack roll made within the area.
Level 18 – Nature’s Dominion:
Your mastery over natural forces culminates in a devastating show of dominance over the battlefield. Once per long rest, as an action, you invoke the full wrath of nature, creating a 60-foot radius zone of natural control centered on yourself that lasts for 1 minute. While within this area:

• Enemy creatures treat the area as difficult terrain and cannot teleport or use extradimensional movement.
• At the start of each enemy's turn within the area, they must make a Strength saving throw. On a failure, they are restrained, silenced, and frightened until the start of their next turn.
• If an enemy fails this save by 5 or more, they are also stunned until the end of their current turn.
• Any creature that fails a saving throw against your spell while in this zone suffers an additional penalty of -3 to attack rolls, ability checks, and saving throws until the end of your next turn.
• The area is shrouded in supernatural overgrowth—vines crawling up buildings, flowers blooming violently from cracks in the ground, and the very air pulsing with primal magic. You may move the zone up to 20 feet as a bonus action on subsequent turns.

Charm Effect: When you activate Nature’s Dominion, all creatures of your choice within the area must make a Wisdom saving throw. On a failed save, they are charmed by you for the duration or until they take damage. While charmed in this way, creatures are incapacitated and have a speed of 0, as if affected by the Hypnotic Pattern spell. They may repeat the save at the end of each of their turns to end the effect.
