Anything to boost Bull Rush/Trip?

[zoobob9]

Are there any items that boost either Bull Rush, Trip, or effective size?

Are there any spells or psiconic powers that increase any of these?

So far I have a ring of Continuous Enlarge Person.

My character is a Goliath Half Minotaur, so he's large with powerful build, so he counts as Gargantuan so far. I have all the feats and whatnot set in place, I only have rooms for items. I'm also unarmed, so weapons won't work.

Armbands of Might (MIC) give a bonus to all Str-based checks, including trip, bull rush, grapple, etc.

Expansion (http://www.d20srd.org/srd/psionic/powers/expansion.htm) can give you two size increases, but it doesn't stack with Enlarge Person. Giant Size (CA) puts you at a set size based on the caster level, up to colossal at 19, again it doesn't stack with other size/form-changing spells or powers.

The feat Knock-Back in Races of Stone increases your bull rush check by an amount equal to your Power Attack penalty, or double that if you're using a two-handed weapon.

Taking a variant of Half-Fiend (http://www.wizards.com/default.asp?x=dnd/we/20060630a) based on a Goristro (FC1) increases your size category by one step and gives +8 Str and Con, and could arguably grant you two slam attacks which are each counted as a two-handed weapon. You can gradually gain half-fiend (http://www.wizards.com/default.asp?x=dnd/sp/20031010a), and don't have to keep taking it until it's finished (http://www.wizards.com/default.asp?x=dnd/sp/20030824a), so make a similar level progression for Half-Goristro (http://www.giantitp.com/forums/showthread.php?t=234089#4) (that one is based on the stat changes for an increase from medium to large).

A ring of Continuous Expansion would cost 14k as opposed to 4k...A bit pricey, but probably better if I can find one.

I have the knockback feat, but forgot that it's doubled when using a two handed weapon. I'm probably going to have to tweak things now to get that up.

Anything that can be placed on a weapon?

Anything that increases your size or effective size (http://www.giantitp.com/forums/showthread.php?p=7081777).

I think there is an enhancement for +4 to trip. Sweeping maybe? I can't remember exactly.

Unless your DM is letting it apply, Enlarge Person does not work on you. As a Goliath, you are a Monstrous Humanoid, and not a Humanoid. Expansion, however, works just fine. It has no such type restriction.

Correct. And neither do the other X person line of spells.

There is a ring of enlargement in savage species that work on monsters. You can use that (expensive though).
