Best spells or powers for punishing anyone too close to me

I have a character with a reach of 20-25 feet depending on the buffs I have operational, with a specialty in grappling. The goal is to grab enemies and drag them to my space—and have my space, or better spaces near me, be very unpleasant places to be. For example, I have a blackguard’s aura of despair, and I’m considering Focalor’s aura of sadness and the enlightened spirit’s aura of menace.

But beyond those save-nuking auras, I’m kind of coming up short on how to most make “near me” be the worst possible place for an enemy to be. I’m looking for passive effects so I can focus my actions on just dragging in as many foes as possible. I figure spells or powers are probably my bet on this front, but I’m not coming up with much:

D&D 3.5e:

  • Acid sheath—2 acid damage per round to creatures in a grapple with me
  • Aura of the sun—1d6 positive energy damage to undead around me each round
  • Aura of cold—comes in lesser and greater varieties, which do 1d6 or 2d6 cold damage, respectively, per round to creatures within 10 feet.
  • Babau slime—1d8 acid damage per round to grappled creatures.
  • Balor nimbus—6d6 (as a 2nd-level spell) fire damage per round to grappled creatures.
  • Body of the sun—1d4/2 levels fire damage per round to creatures within 5 feet.
  • Corona of cold—1d12 cold damage per round, and applies a −2 penalty to Strength and Dexterity and halves speed, to creatures within 10 feet.
  • Negative energy aura—1 damage per 3 levels, or 2 healing for undead creatures, each round, in 10-ft radius.
  • Positive energy aura—1 healing per 3 levels, or 2 damage for undead creatures, each round, in 10-ft radius.
  • Pulse of hate–2d6 “unholy” damage per round in 10-ft radius.

Pathfinder

  • Cape of wasps—described as a wasp swarm sharing your space, which means other creatures sharing your space (e.g. creatures you’ve grappled under 3.5e rules, which we are using) arguably take the 2d6+poison swarm damage of the wasp swarm each round. The spell doesn’t come out and say that, though, and sharing a space with someone is a lot harder in Pathfinder than it is in 3.5e, so it’s unclear if this was intended functionality.

So what I’m looking for are official spells or powers from D&D 3.5e (all WotC-published sources as well as Dragon and Dungeon magazine issues, including 3.5e-legal 3e material) or Pathfinder (all Paizo-or-Dreamscarred-Press-published sources) that introduce some kind of emanation or aura that extends from my space, out to 20 feet or less (if it’s larger, I have no need to drag them into it). The emanation must last for some period of time, the longer the better. I would restrict this more (class, level, effects), except that I’ve already done a bunch of research and come up with nearly nothing. My character is a psion egoist, but adaptation or multiclassing might be possible. However, Epic and Mythic material are both banned.

For this question, I’ll hear out answers that include polymorph, but know that I view polymorph pretty dimly and also that it would conflict with some of the things that my character is already doing (i.e. various character features would be lost), so polymorph options rate pretty poorly in my estimation—I’d appreciate it if we’d restrict mentions of it to truly stand-out effects you couldn’t get elsewhere.
