Bound. The titanium teddy bear is magically bound to a creature. As long as the teddy bear and its creature are on the same plane of existence, the bound creature can telepathically call the teddy bear to travel to it, and the teddy bear knows the distance and direction to the amulet. If the teddy bear is within 60 feet of the bound creature, half of any damage the wearer takes (rounded up) is transferred to the teddy bear. If the titanium teddy bear is reduced to 0 hit points, it reverts to its smaller form to repair. Regeneration. The titanium teddy bear regenerates 1 hit point every 10 minutes while it is not in defender mode, even if it is at 0 hit points.
Fist. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 1 bludgeoning damage. Protect. The titanium teddy bear attempts to intercept all attacks sent at a creature it is protecting within 5 feet of it. Until the star titanium teddy bear's next turn or if the creature ends its turn more than 5 feet away from the titanium teddy bear, the creature has three-quarters cover against all attacks (+5 to AC and DEX saving throws). If an attack misses the protected creature but hits the teddy bear's AC, the teddy bear takes the damage from the attack instead.
Shield. When a creature makes an attack against the titanium teddy bear's bound creature, the teddy bear grants a +2 bonus to the bound creature's AC if the teddy bear is within 5 feet of the wearer.
The titanium teddy bear is a nonmagical construct that baffles the minds of scientists and arcanists alike. Only it's original creator, Radu the Goblin, knows the secret to how it functions. While it is dormant, the titanium teddy bear looks like a normal green teddy bear, created mostly out of burlap and stuffed full of feathers. It has a big smiley face and stubby little arms that hang limply at its sides. However, when it is activated (which is done by placing the teddy bear onto the ground) it swells in size until it stands at roughly 6 feet in height. In defender mode, it has one directive: protect. It will follow behind its bound creature silently unless given a command. In combat, it's primary objective is to protect its bound creature or a creature that its bound creature designates.
The titanium teddy bear is comfortable in any environment, as it is nonflammable, waterproof, and so on. It can and will go wherever its bound creature goes.
