The Baron Nashor is hard to kill.

It is NEVER worth it to "Solo" Baron (Unless you are full gear and kill him in a couple of seconds). Because:
- You waste lots of time doing it alone
- You can be easily ganked/killed
- After a small push you can call 2 or 3 teammates and do it quickly, so why do it alone? It's a team type game after all, right ?!
- Take a look at this link: When should I Baron?
But Michel, I really want to give it a try, so which champion is good
for it?
Basically Attack Damage based Champions:
Those 3 are the best for the service.
- Tryndamere has a huge amount of damage and his ult can keep him alive for extra damage.
- Vayne does True damage, and with enough attack speed and damage you will not have any trouble at all
- Kog'maw has good skill rotation, and he match really well with Madred blood razor.
Others good champions are:
- Gangplank
- Shaco
- Heimidinger
- Olaf
NOTES: At 15min you can do Baron between 15 and 30 seconds with 3 level 12 without much trouble, or even 2 if you two are fed as hell (bot style for the win). So go for it with a couple of friends and you will be fine. Care for wards (Oracle or pink ward here). Check out for the enemy invasion too.
If you're going for pure AP, then obviously you want to have a Rabadon's Deathcap. It grants 120 AP, and has a unique passive that modifies your AP up 30%.
Another item you'll almost certainly want is Seraph's Embrace. It only grants 60 AP, but grants 1000 mana, and has a unique passive that grants an additional 3% mana as AP, this makes it worth more than a second Deathcap as soon as you have 1000 mana from other sources.
Lichbane is worth only 87.5 AP, not worth taking in a pure AP build
Rod of Ages is worth about 100 AP, still not worth taking in a pure AP build
Mejai's Soulstealer, fully stacked, is worth 180 AP, definitely worth taking if you can keep the stacks up. It drops to 124 on a single death. (13 stacks)
Deathfire Grasp is worth 120 AP, exactly as much as Rabadon's Deathcap, and would make a good filler item, as while the Active won't stack, you will get the 10% cooldown reduction repeatedly.
Zhonya's Hourglass is also worth 120 AP, and can be stacked for Armour.
Add in Elixer of Brilliance, and Exalted with Baron Nashor for an extra 80 AP and 10% CDR
Final Build: Boots, Rabadon's Deathcap, Seraph's Embrace, Deathfire Grasp, Zhonya's Hourglass, Mejai's Soulstealer. Elixer of Brilliance and Exalted with Baron Nashor.
=(120+60+120+120+120+40+40+3%mana)*1.3 = (620 + 3% mana) * 1.3 = 884 + 3.9% mana.
This itemization is the best you can do with boots for a generic champion.
This should work for almost any given mana'd champion with any given rune/mastery set. Here is a link to this build on Anivia (my main) for 1166 AP
Edit: Sorry, I missed the part about 3v3, That section below:
3v3
Rabadon's Zhonya's, and Mejai's are all disabled, as are Exalted with Baron Nashor and Elixer of Brilliance.
Wooglet's Witchcap, while only 100 AP, multiplies AP by 1.25, and so is still worth taking.
Exalted with Baron Nashor is replaced by Crest of Crushing Wrath, also worth 40 AP, while Elixer of Brilliance is replaced by Ichor of Illumination, which yields 64 AP, up from 40.
Additionally, the 2 altar bonus from Twisted Treeline gives an extra 10% AP. In total the build consisted of 3 Deathfire Grasp's, Seraph's Embrace, Boots, and Wooglet's Witchcap, and I was able to get 1131 AP.

Bonus HP acts exactly like regular HP. It is subject to the same damage reduction/amplification from resists. In addition, it is added to both your current and maximum health, but the additional max HP is only temporary.
At the expiration of the spell, any bonus HP you received will stay. The exception to this is if your current HP would be greater than your regular, unbuffed max HP. If this is the case, your HP will be reduced to your max HP.
For example, if you're at 400/1500 HP and you get Wild Growth'd for 300 HP, you'll be at 700/1800. If you proceed not to take any damage, you will be at about 700/1500 at the end of the 7 seconds.
However, if you're at 1500/1500 HP and you get Wild Growth'd for 300 HP, you'll be at 1800/1800. Suppose you take 200 HP of damage. This time, when the spell expires, you'll lose your extra HP. The 1600/1800 HP you have just before the ult wears off will become 1500/1500, since you cannot have more current HP than maximum HP.
One thing to note, by the way, is that all the current sources of bonus HP actually increase your maximum health (temporarily), meaning that % max HP damage sources will do slightly more damage than if you had unbuffed health.
