As requested, here's that old build of mine:
Warforged Cleric 3 (travel & law domains)/Totemist 2/Landforged Walker 5/Sapphire Hierarch 10
*travel domain for survival for Landforged Walker, law domain for Sapphire Hierarch
You get 9th level spells, a plant form that you can boost with incarnum, and access to DMM silliness. This would make a very strong grappler build. Also consider that you'd get Huge shapes 5 levels earlier than a druid. At level 10 you could have a huge Treant with 29 Str, boosted with Girallon and/or Kraken soulmelds, with Divine Power on top. By level 12, you can be an Iron Maw/Octopus Tree/Tendriculous boosted even more with Righteous Might. I think that's a grapple bonus of +47 (give or take a few). Oh, and you can get 8 attacks with the Octopus Tree.
level 12 grapple: 12(BAB) + 10(str) + 8(huge) + 3(div.power) + 6(righteous might) + 14(Girallon) +4(kraken) + 4(imp.grap) = 61
- a few buffs, Iron Maw, Righteous Might, Divine Power, soulmelds, no items
