Artus Cimber

Artus wears the Ring Of Winter. He and the ring can't be targeted by divination magic or perceived through magical scrying sensors. While attuned to and wearing the ring, Artus ceases to age and is immune to ❄️ Cold damage and the effects of extreme cold.
Artus wields Bookmark a +3 dagger with additional magical properties. As a bonus action, Artus can activate any one of the following properties while attuned to the dagger, provided he has the weapon drawn:
list
Cause a blue gem set into the dagger's pommel to shed bright light in a 20-foot radius and dim light for an additional 20 feet, or make the gem go dark.
Turn the dagger into a compass that, while resting on your palm, points north.
Cast Dimension Door from the dagger. Once this property is used, it can't be used again until the next dawn.
Cast Compulsion (save DC 15) from the dagger. The range of the spell increases to 90 feet but it targets only spiders that are beasts. Once this property is used, it can't be used again until the next dawn.

Artus makes three attacks with Bookmark or his longbow.

Melee Weapon Attack +8 to hit, reach 5 ft., one target. 7 (🎲1d4 + 5) 🏹 Piercing damage.

Ranged Weapon Attack +5 to hit, range 150/600 ft., one target 6 (🎲1d8 + 2) 🏹 Piercing damage.

The Ring of Winter has 12 charges and regains all its expended charges daily at dawn. While attuned to and wearing the ring, Artus can expend the necessary number of charges to activate one of the following properties:
list
Artus can expend 1 charge and use the ring to lower the temperature in a 120-foot-radius sphere centered on a point he can see within 300 feet of him. The temperature in that area drops 20 degrees per minute, to a minimum of −30 degrees Fahrenheit. Frost and ice begin to form on surfaces once the temperature drops below 32 degrees. This effect is permanent unless Artus uses the ring to end the effect as an action, at which point the temperature in the area returns to normal at a rate of 10 degrees per minute.
Artus can cast one of the following spells from the ring (spell save DC 17) by expending the necessary number of charges: Bigby's Hand (2 charges) the hand is made of ice, is immune to ❄️ Cold damage, and deals 🔨 Bludgeoning damage instead of 🌀 Force damage as a clenched fist, Cone Of Cold (2 charges), Flesh To Ice (3 charges); as flesh to stone except that the target turns to solid ice with the density and durability of stone, Ice Storm (2 charges), Otiluke's Freezing Sphere (3 charges), Sleet Storm (1 charge), Spike Growth (1 charge) the spikes are made of ice, or Wall Of Ice (2 charges).
Artus can expend the necessary number of charges and use the ring to create either an inanimate ice object (2 charges) or an animated ice creature (4 charges). The ice object can't have any moving parts, must be able to fit inside a 10-foot cube, and has the density and durability of metal or stone (Artus's choice). The ice creature must be modeled after a beast with a challenge rating of 2 or less. The ice creature has the same statistics as the beast it models, with the following changes: the creature is a construct with vulnerability to 🔥 Fire damage, immunity to cold and ☠️ Poison damage, and immunity to the following conditions: Charmed, Exhaustion, Frightened, Paralyzed, Petrified, and Poisoned. The ice creature obeys only its creator's commands. The object or creature appears in an unoccupied space within 60 feet of Artus. It melts into a pool of normal water after 24 hours or when it drops to 0 hit points. In extreme heat, it loses 5 (🎲1d10) hit points per minute as it melts. Use the guidelines in chapter 8 of the Dungeon Master's Guide to determine the hit points of an inanimate object if they become necessary.
