Most broken thing you can do at each level

[Undone]

What do you think the most broken things you can do at each level are?

Below is a starting point but nothing more. While this isn't intended to be a spell's only section I suspect most of it will end up like that.

1: Color spray
2:
3:
4:
5:
6:
7:
8:
9: Magic Jar
10:
11:
12: Possibly Quickwood Wild shape.
13: Simulacrum
14:
15:
16:
17: Wish
18: Spam gate solars (Summoner SLA's)
19:
20:

Don't forget the true name arcane discovery. At level 15, you can spam greater planar binding for a 18-HD outsider, except you don't have to pay or bargain with it.

[Kirth Gersen]

I would have put 9: plane shift

[CWheezy]

Simulacrum is 13, not 15

[ArmouredMonk13]

Magi have 15-20/x2 spells by 5th level through arcane pool, thus spellstrike one round, spell combat afterwards and you can deliver max of 20d6 electric damage in one round if you crit twice. You only have about a 9% chance of doing this of course, but still, its pretty powerful.

[Mathius]

Not sure what the best one is but at low levels cleave plus power attack on barbarian often means two dead critters every turn.

[SmiloDan]

Darkvision + sneak attack + opponents without darkvision in the dark?

[Avatar-1]

Throw bombs at 'em, shoot 'em with a gun.

Have fun :)

Honestly? Show up. Why? Because you get new opportunities to stretch, distort, and interpret the rules to your advantage every time you game, no matter what level you are :)

[prototype00]

Lvl 10: 12d8 weapon damage (as in your iterative attacks do 12d8 damage)
Lvl 15: Guaranteed 288 + Str and other bonuses points of damage as a standard action attack.
Lvl 20: Guaranteed 384 + Str and other bonuses points of damage as a standard action attack.

[SmiloDan]

Level 1: 2-handed raging power attack.
Level 2: Multi-class into magus, 2-handed raging power attack while enlarged.

[Mirrel the Marvelous]

Level 3: Combine Blood Money and Masterwork Transformation, sell for infinite cash.
-and-
Level 3b: Summon Cacodaemon (from Horsemen of the Apocalypse) to suck out the souls of defeated enemies for even more cash!

[ArmouredMonk13]

Levels 1-4, be a barbarian or alchemist. Levels 5-20, be a good spellcaster. Levels 1-20, be a summoner. That pretty much sums up the broken things you can do each level.

EDIT:make that be a good barbarian/alchemist/spellcaster/summoner. :}
