; Golems Golems Golems
The market price of a golem is increased by 5000 GP per additional HD and 50,000 GP per a size increase. With the Craft Construct feat, you only have to pay half cost, and as a result, you can create a 54 hit dice iron golem for 195,000 gold pieces; it will have 337 HP, keep its immunity to magic, have a BAB of +36 and have a DC 37 poison breath weapon. For reference, a level 20 character can be expected to have 760,000 gold pieces, easily letting you afford 3 of these bad boys, along with a headband of intellect +6 and a few miscellaneous items. Lower level characters can triple advance weaker constructs, to similar results. 

;Broken Spells
* Forcecage, a level 7 spell which costs 1500 gp to cast (and also allows NO saving throw and NO spell resistance, imprisoning any creature of 20x20 size or less in an indestructible force barrier. Leave an Acid Fog and Dimensional Anchor spell on it and teleport away, kills nearly anything with no save allowed, but that's beside the point).

If you're in Pathfinder, take the Siege Mage archetype, which is a Wizard archetype that replaces the standard Wizard's small animal familiar for a magic cannon.  By level 7, you should have enough money to afford a Fiend's Mouth Cannon, and be able to cast all the spells needed to carry a siege weapon with you anywhere you go, whether that be the bathroom or swimming pools: Floating Disc, Shrink Object, Levitate, etc.  In combat, cast ''Unseen Servant'' to act as your cannon crew, so you're free to cast spells.  The Fiend's Mouth cannon does 8d6, or 14d6 with explosive ammo.  At level 13, take the "Vital Strike" feat to double damage for any one weapon attack roll, making it 28d6 damage.  And this is before enhancement bonuses like Enlarge.  Combine with the golems above to build a robocop body around your pet cannon.
