Arcane Block v2.

The Arcane Block is in the shape of a hexagon with it going 0.5 inches deep and sides being 2 inches each. The border of the Block is made of either a thick, dark wood with glowing dark blue veins within it or a polished, pale stone with golden veins running through it. The center of the block is filled with 5 dark-gray stone pieces with each piece having a rune on it. The runes will glow blue once the block is activated.

Rune of Combustion. Hits any object within 20 ft causing a small, but intensive blast that covers 50% of the terrain within a 5-foot radius with fire (creatures within the blast receive 1d10 fire damage and 1d10 force damage)

Rune of Madness. Shoots towards intended target within 10 ft and attaches itself to the head of the target causing the target to attack the closest creature to it (duration: 30 seconds or 5 rounds) unless the creature is immune to being charmed. Every round, the creature can make a Wisdom saving throw to attempt the escape the effects of the rune. On a succesful saving throw, the creature will become free from the rune and will fall prone; the rune will then return to the Arcane Block. On a failed throw, the creature will remain under the control of the rune and will attack the closest creature.

Rune of Resonance. You can throw down the rune onto an object or area of emotional/physical/spiritual significance. As an action or bonus action, you can open a rift in the sky of your current plane, as long as the plane you are in matches the plane that your runestone is in and as long as you are within a 100-foot radius of the runestone. From the rift, a beam of pure white energy will fall down onto you and will bring you back to your runestone through another beam of energy. Both beams will last for 1 round. Any creature that attempts to enter the beams will take 50% of their max hitpoints worth of damage

Rune of Paving. The rune will break into 5 separate parts that will form a bridge of continuously flowing, but solid, magic; the bridge has a maximum length of 25 feet and will disappear once the pieces are summoned back together

Rune of Ruination. The ruin will spiral around the user at the edge of a 3-foot radius, causing a runic circle to form out of glowing white, blue, and gold magic, in the air in front of the caster. After 2 minutes of charging, surrounding energy will be taken from creatures within a 25-foot radius and from other magic items within that radius; all creatures within the radius must make a charisma saving throw or fall to the ground and take 8 necrotic damage and become exhausted (level 2). Then, the runic circle will then unleash a large beam of destructive energy that continues for 50 feet in a line. Creatures that get hit by the beam will take 3d12+5 (minimum of 20) radiant damage. Terrian that is hit will be engulfed in bright purple and white flames. The beam will last for up to 18 seconds (3 rounds) while the caster is concentrating and can be directed to a different point, up to 50 feet away from the original point. After the runic circle dissipates, the runestone will return to the Arcane Block, and won't be able to be used for the next 24 hours. The caster will also be prone and will have a disadvantage on all checks and saving throws for the next 12 hours

The Arcane Block can only be broken by the user and the combination of the powers of 3 celestials.

Runes can be summoned back to the arcane block at any point, but once they have been taken out of the block, a charge is expended.

Runes can be used in combination with each other as an action and then a bonus action.
