Cherry blossom giant

Treeform stasis. The Cherry Blossom Giant can transform into a huge, unmoving cherry blossom tree as an action, merging with the surrounding nature. In this state, it is indistinguishable from an ordinary tree and is immune to all conditions. It cannot move, attack, or take any actions until the magic word is spoken, awakening the giant. The giant is aware of its surroundings while in this state. A successful DC 20 Wisdom (Perception) check is needed to recognize the tree as the giant.

Hoarders bough. The Cherry Blossom Giant stores its most prized possessions within the heartwood of trees it has enchanted. As a bonus action, the giant can summon any object it has stored in a tree within 60 feet, causing it to magically appear in its hands or at its feet. The tree must be intact for this ability to work.

Cherry Blossom Aura. A 20-foot radius around the giant is filled with floating cherry blossom petals, lightly obscuring the area and providing cover to the giant and its allies. Creatures within this aura must succeed on a DC 16 Wisdom saving throw at the start of their turn or be charmed until the end of their next turn. Creatures charmed in this way become docile, unwilling to attack the giant or its allies.

Multiattack. The Cherry Blossom Giant makes two attacks: one with its Blossom Blade and one with its Vine Whip.

Blossom Blade. Melee Weapon Attack: +10 to hit, reach 10 ft., 1 target. Hit: 22 (3d10 + 6) [slashing] damage plus 7 (2d6) [psychic] damage. The target must succeed on a DC 16 Wisdom saving throw or become frightened until the end of its next turn

Vine Whip. Melee Weapon Attack: +10 to hit, reach 20 ft., one target. Hit: 18 (3d8 + 6) [bludgeoning] damage, and the target is grappled (escape DC 16). Until this grapple ends, the target is restrained, and the giant cannot use its Vine Whip on another target.

Blossom Burst (Recharge 5-6). The Cherry Blossom Giant releases a burst of red cherry blossoms in a 30-foot radius centered on itself. Each creature in the area must make a DC 16 [Dexterity] saving throw, taking 45 (10d8) [radiant] damage on a failed save, or half as much on a successful one.

Action Ranged Attack. RangedWeapon Attack: +# to hit, range #/# ft., # target. Hit: # (#d# + #) [damage type] damage.

Counterspell. The Cherry Blossom Giant can cast [Counterspell] as a reaction when it sees a creature within 60 feet of it casting a spell. The giant uses its [Wisdom] modifier for this reaction. When [Counterspell] is cast, the giant makes a spellcasting ability check (DC 10 + the spell’s level). On a success, the spell is negated.
