Heroic Perk (Rocket Launcher): Baron's basic attacks deal more damage than usual when building Weapon Power (his basic attacks have a 130% ratio, compared to 100% on most other heros). Furthermore, his basic attacks deal AoE damage and can hit multiple enemies at once, dealing full damage to each enemy effected. The explosion AoE damage is decreased when hitting lane minions. To balance this Perk, Baron doesn't gain very much natural attack speed when leveling up.

A (Porcupine Mortar): This ability has two charges, both of which are on a very short cooldown. Upon selecting a target location, a mortar shot is immediately fired to a hexagonal, marked area (this area is visible to both your teammates and enemies). However, this shot's animation is slow, meaning that the mortar actually lands and deals its damage a second or two after the area is marked. Furthermore, this ability contains a built-in slow, which increases with WP, while CP increases the range of this ability. While this ability has both a crystal and weapon ratio, the crystal ratio is much higher. This ability's base damage is crystal. When building WP, this ability isn't often used, and if it is, its for the slow it contains. This slow helps Baron, a mostly immobile hero, keep up with enemies or kite them. With CP, this ability is your main source of damage, and extremely spammable (think Skaarf/Celeste's A, but with a slightly longer cooldown). This ability is also used to push enemies into your second Mortar, or to zone them into your C.

B (Jump Jets): Upon selecting a target location, Baron charges up to launch himself to the target location. When Baron lands, his next basic attack fires instantly, and the one afterwards reloads instantly, allowing Baron to fire two basic attacks in very quick succession. Also upon landing, Baron gains a slight speed buff for a second or two, which is increased with WP. Building WP decreases the charge time before his jump, and at 200 WP, gets rid of it entirely. Building CP significantly increases the range of this ability, however, the further away the target location, the longer the charge up time. Furthermore, basic attacking decreases the ability's cooldown by 3 seconds for each basic attack, allowing WP builds to use it very often. Overdriving this ability makes you immune to most CC (crowd control, like stuns or silences) while in the air and for a brief time after landing. When building WP, this is your main form of "attack speed" and burst. It is also a great way to quickly evade skillshots or abilities that would normally devastate Baron. When building CP, this ability won't be used very often, but can be used situationally to get away from a sticky situation or to chase an enemy.

C (Ion Cannon): Baron marks a target location, preparing for a devastating AoE nuke. This ability can be placed anywhere on the map, however, the nuke is not instantaneously activated. Instead, this ability only deals its damage 3 seconds after the target location is marked. What makes this ability interesting is that only you and your allies can see the marked location, but your enemies can only see it 0.9 seconds before detonation, giving your enemies a little bit of time to reflex block this ability's devastating damage. However, activating this ability has a visual and audible que, meaning that enemies can prepare to reflex block the ability before the marked location is revealed to them. This ability deals decreased damage the further enemies are from the center of the marked location. Also, each rank of this ultimate increases Baron's basic attack range, transforming him from one of the shortest ranged heros at levels 1-5 to the longest ranged hero at level 12. This ability has both a weapon and crystal ratio, but once again, the base damage is crystal and the crystal ratio is much higher. When building weapon, this ability is mainly used to help increase your basic attack range, but the base damage on this ability is still high, so using it as an extra source of damage is a good idea as well. When building CP, this ability is a secondary source of damage from your A. Building CP makes this ability a devastating nuke, so good timing and placement can be rewarded with extremely high AoE damage.

As of this publishing of this build guide, WP Baron has proven to be the better build in terms of effectiveness and competitive play. While both WP and CP are viable, WP is definitely the easier of the two to play. With CP, your A and C are your main sources of damage, and while they're a heavy source of damage, they're extremely skillshot-related. Your A is also easy to dodge while your C is easily reflex blocked. However, once people begin to figure out how to land his abilities, CP will become increasingly more common as CP Baron's late-game scaling and damage are extremely strong. However, at the moment, WP is the way most people prefer to play Baron.

WP Items:
-Sorrowblade: This item is a core item on almost every WP hero. With Baron, this is no different. This item helps your basic attacks deal much higher damage, and the +150 WP also gives your abilities the most power they can possibly receive from one item.
-Breaking Point: If you can maintain Breaking Point stacks throughout a fight, then this item is the strongest WP item in the game, hands down. At just 10 stacks, this item gives +155 WP (slightly more than a Sorrowblade), as well as +35% attack speed (at all stack counts)!
-Tyrant's Monocle: Crit is extremely effective on all WP carries. Because the Sorrowblade and Breaking Point give a lot of weapon power, the crit chance and damage enabled by the Tyrant's Monocle is the best way to maximize the WP received. Especially because Baron's basic attacks deal AoE damage, the chance to land crits on every enemy is a huge deal.

CP Items:
-Shatterglass: +150 CP is self-explanatory. This item allows your abilities to pack a huge punch, and the extra bonuses received from building extra CP can be achieved quickly with this item. Furthermore, because your A already applies a slow, a Frostburn isn't necessary.
-Broken Myth: This item should be build on every CP carry, and for good reason. The shield pierce is extremely helpful, and the damage amplification to your abilities is immensely powerful!
-Clockwork: Spam, spam, spam! This item allows you to do this with a ton of cooldown, extra energy, and energy regen. Furthermore, this item amplifies your CP by 30%, and when combined with the two above items (Shatterglass and Broken Myth), can give more CP than an Eve of Harvest!

Early Game (0-1 T3 items):
In the early game, WP Baron is somewhat weak. This is due to a combination of extremely slow attack speed and energy problems if abilities are spammed. It's best to concentrate on farming during this phase, and of course, rotate down to jungle if a fight breaks out that your teammates can't handle (for instance, if your jungler is a late-game bloomer, rotate down, but if your jungler is a Koshka, chances are they won't need help).

Mid Game (2-4 T3 items):
The mid game is Baron's strongest phase. After getting your second T3 item, you should be extremely confident. Continue to farm, but more loosely, be prepared to rotate at all times. You can easily win teamfights during this phase because of how much damage you do. However, make sure your team is making the most out of their rotations, and take objectives as often as possible. Hopefully, you can snowball during this phase for an easy victory.

Late Game (5-6 T3 items):
Due to the inclusion of the item, Breaking Point, Baron can still do pretty great AoE damage in the late game. However, you need to play more conservatively during this phase, and not be as aggressive as you were in the Mid Game. Chances are, you can no longer insta-melt an enemy at only a few Breaking Point stacks, so you will need to concentrate on getting these stacks before you make any aggressive maneuvers.

General Tips:
-Focus on those Breaking point stacks in late game fights. Stack by attacking the enemy roamer (or whatever Melee heroes are on the enemy team). After you have 10+ stacks, switch to the enemy lane carry and kill this hero as quickly as possible. The lane carry is often the highest damage dealer on the enemy team, so eliminating him/her is imperative.
-Save Jump Jets. Don't necessarily use this ability at the start of fights. While you should be using it often with a WP build, be smart with this ability.
-Ion Cannon usage. While this ability isn't an extremely high source of damage with WP, this ability's damage can be the difference in fights. Try to place it in places where you'll be able to hit multiple enemies, and ensure that the location you place it in is also one where enemies will be staying.
-Porcupine Mortar usage. In reality, I rarely seem to use this ability when building WP. The slow is pretty substantial, however, so use it to zone your enemies out of an area. Just beware that without Halcyon Chargers, this ability guzzles more energy than a diesel truck.

Early Game (0-1 T3 items):
Just like with WP Baron, CP Baron's early game is weak. Focus on farm and rotate when you're needed.

Mid Game (2-4 T3 items):
CP Baron's mid game is meh at best. You should focus on farm as much as possible, and rotate down to your teammates when fights break out. Your main goal is to not be starved out during this phase of the game, and make it to your late game as soon as possible.

Late Game (5-6 T3 items)
CP Baron's late game is INSANE. With 3 damage items under your belt, and at least one defense to be able to take some damage, you will be extremely hard to stop. Of course, you are still squishy, so try to stay as far back from the front line as you can. Try your best to get and maintain all 5 Broken Myth stacks, and your damage will be unparalleled during late game fights.

General Tips:
-Broken Myth stacks. It is extremely important to gain these and maintain them during a fight to maximize your damage! Broken myth amplifies your damage (multiplies it by an amount based on your stacks), so in order to be at your most devastating state, you must have a high amount of these stacks.
-Porcupine Mortar usage. This is, of course, your main source of damage as CP Baron. This ability is hard to land individually, however, waiting just a little bit longer and chaining your two charges is the most effective way to use it. By doing this, you can zone your enemies into hitting one of the two mortars, instead of them juking out both.
-Jump Jets usage. With CP, this ability won't be used all too often. However, its range can help with chasing enemies or potentially getting out of a sticky situation. Once again, be smart with this ability, and don't position yourself into a risky spot.
-Ion Cannon usage. If possible, try to wait until you have 3-5 Broken Myth stacks to use this ability, and this ability's already extremely high damage will be amplified even further. Landing this ability consistently, and on multiple enemies, is key to winning teamfights.

I hope you guys have a lot of success with these builds, and most importantly, have as much fun as I do when playing Baron. This is my second vainglory guide, my first being a Stormcrown Taka guide (http://www.vaingloryfire.com/vainglory/guide/stormcrown-cp-taka-16426). I would greatly appreciate some thumbs up on these builds if they help you out, and of course, feel free to tell me some criticism, questions, or tips! Thanks again!
