Has this man heard of the "shift" key?
But this description is confusing--like, it's polygonal, traps people within itself, that part I get. Until someone sacrifices themselves is a bit OP. The last part confuses me, though. Fog-like matter, I get that part, but what does it have to do with its ability? Is it its shape? Does it trap people via the fog? What does it do? The most confusing part is "shine of love". Huh? What the hell is that supposed to mean?
Last part is the stats. Personally, I'd switch the range and the durability. I think the range would be where the majority of the Stand's strength lies, so the other stats would be a bit lower, which is sort of what you did here.
For reference, these are the typical scaling for stats:
A - Superior
B - Above average
C - Average/The abilities of a normal human.
D - Below average
E - Abysmal
Some As and Bs scale different from others, same with C-E. Araki's stats CAN be inaccurate with the Stand's abilities demonstrated, such as The Emperor, a Stand that shot a bullet, redirected it around Silver Chariot's rapier, then redirected back to where it was.
