slow increases
more dmg to illus
and remove manacost at lvl 3

ain't that enough?

Actually, the total slow decreases at higher levels. But it deals more damage to summons, and various other stats are improved (manacost).

Have some shinjo:

Then, it has an attack/movement update frequency of 2/3/5 depending on the level.

• For Stone Gaze level 1, here's what will happen:
  • Against heroes:
    0s: ms and as slowed by 100%
    2.5s: ms and as slowed by 50%
    5s: end of the purge
    
  • Against nonhero units:
    0s: ms set to 0, as slowed by 100%
    2.5s: ms set to 0, as slowed by 50%
    3s: ms and as slowed by 50%
    5s: end of purge
• Stone Gaze level 2:
  • Against heroes:
    0s: ms and as slowed by 100%
    1.67s: ms and as slowed by 66.7%
    3.33s: ms and as slowed by 33.3%
    5s: end of the purge
    
  • Against nonhero units:
    0s: ms set to 0, as slowed by 100%
    1.67s: ms set to 0, as slowed by 66.7%
    3s: ms and as slowed by 66.7%
    3.33s: ms and as slowed by 33.3%
    5s: end of the purge
• Stone Gaze level 3:
  • Against heroes:
    0s: ms and as slowed by 100%
    1s: ms and as slowed by 80%
    2s: ms and as slowed by 60%
    3s: ms and as slowed by 40%
    4s: ms and as slowed by 20%
    5s: end of the purge
    
  • Against nonhero units:
    0s: ms set to 0, as slowed by 100%
    1s: ms set to 0, as slowed by 80%
    2s: ms set to 0, as slowed by 60%
    3s: ms and as slowed by 40%
    4s: ms and as slowed by 20%
    5s: end of the purge

And maybe Yendor:

Lvl.3: (with lvl.1 values to compare)
Against heroes:
0s: ms and as slowed by 100% (100% lvl.1)
1s: ms and as slowed by 80% (100% lvl.1)
2s: ms and as slowed by 60% (100% lvl.1 at 2.5 seconds: 50%)
3s: ms and as slowed by 40% (50% lvl.1)
4s: ms and as slowed by 20% (50% lvl.1)
5s: end of the purge (same at lvl.1)

So yes. leav it at lvl.1 if you only want the slow.
But lvl.1 costs 100 mana, lvl.3 costs nothing.
Also the 400 damage difference against illusions is a good point for leveling it too.

Actually, this has been discussed before, just search. You didn't, did you?

Actually he wasn't even posting on mech, but w/e.

At least here the facts legitimately contradict the hero page.
