League of Legends : The Breakdown

A breakdown of many of the major themes, items and buildings in League of Legends
(General gameplay, not character specific)

TURRET DATA

Turrets do more damage with each successful hit on each single target, increasing by +22.5% each hit after the first with a cap of +135%

Damage to turrets with your basic attacks is worked out at basic damage + either 100% of your bonus damage or 40% of your bonus ability power, whichever is highest

If there are no enemy minions in range, a turret gains approx. 49% physical damage reduction and 29% magic damage reduction

Inner turrets are invulnerable till the outer turrets are destroyed

Turrets do more damage as the game progresses

• Outer turrets take 8 minutes to reach a maximum damage, with a minimum of 152 AD and a maximum of 200 AD
• Inner turrets take 11 minutes to reach a maximum damage, with a minimum of 197 AD and a maximum of 263 AD
• Inhibitor turrets take 20 minutes to reach a maximum damage, with a minimum of 201 AD  and a maximum of 330 AD
• Nexus turrets take 38 minutes to reach a maximum damage, with a minimum of 115 AD and a maximum of 343 AD

As a rule of thumb, a warrior minion takes 2.5 hits to die, while caster minions take 1.5 hits

If you have around +25 bonus damage you can happily steal the last hit

Turret priorities go in the order of: Enemy champion who's attacked allied champion -> Pets -> Minions -> Enemy champion

The turret will only change targets once it's current target is killed UNLESS it sees an enemy champion attack an allied champion.


TELEPORTING

You can teleport to:

• Friendly turrets
• Friendly minions
• Friendly pets
• Sight Ward and Vision Ward, though this will reveal the ward to enemies (unless in fog of war)
• Flags (Rally / Demacian Standard)
• Teemo's Noxious Mushrooms
• Shaco's Jack in the Box

You might think you can, but cannot teleport to:

• Friendly copies (Shaco's Hallucinate, Mordekaiser's Child of the Grave)
• Non-destructable traps (Caitlyn's Yordle Snap Trap, Nidalee's Bushwhack)
• Friendly inhibitors

Teleport can be cancelled, however it goes on a brief cooldown (180s rather than 300s)

If a minion is being teleported to, it becomes invulnerable (and won't move/attack) during the duration

Teleporting to a turret does NOT make it invulnerable, and if it is destroyed you will still teleport there

Teleporting particles can be seen through brush


MINIONS

Begin spawning 1min 30s into the game, and then spawn every 30s

Grow stronger every 3mins

Deal 50% more damage to turrets than to champions and other minions

There are currently 5 minions types: Melee, Caster, Siege, Super and Anti-Turret

Melee and Caster are the basic types of minion, the amount they give on death grows by +1g after the first wave and +1g every 5 minutes after that

On the Twisted Treeline, they give 29g (melee) and 22g (caster) each initially, while on Summoner's Rift they give 22g (melee) and 16g (caster)

The siege minion gives 36g initially on Twister Treeline, and 27g initially on Summoner's Rift, growing by +1g every 2-3 minutes

Siege minions will also spawn once per 3 waves for the first 20 minutes, then once per 2 waves afterwards

Melee, Caster and Anti-Turret minions take 100% tower damage, while Siege and Super minions only take 50%

If all inhibitors are destroyed, 2 super minions will spawn in each lane per wave

Minions have the unique ability of Call For Help, this is a behaviour based ability which bucks the trend of their otherwise simple follow-route, kill routine

Minion priorities based on Call For Help are as follows:

1. Allied champion attacked by enemy champion
2. Allied champion attacked by enemy minion
3. Allied minion attacked by enemy minion
4. Allied minion attacked by enemy turret
5. Allied minion attacked by Enemy champion
6. Closest enemy minion
7. Closest enemy champion

Minions, unlike turrets, will not keep attacking till their current target is dead, if a higher priority situation arises.

E.g. If it's simply attacking the closest enemy minion, and an allied champion is attacked by an enemy champion, all near-by allied minions will begin attacking the enemy champion. However, minions only re-evaluate their situations every few seconds, unless their current target dies or becomes unavailable (walks into brush)


BUFFS

(Unfortunately I'll be ignoring Dominion for this section)
Summoner's Rift buffs include:

• Blessing of the Lizard Elder (Red Buff)
• Crest of the Ancient Golem (Blue Buff)
• Exalted with Baron Nashor

Twisted Treeline buffs include:

• Blessing of the Lizard Elder (Red Buff)
• Crest of Crushing Wrath (Brown)
• Crest of Flowing Water (Grey)
• Crest of Nature's Fury (Green)

The crests of Flowing Water and Nature's Fury last 1min each, while Crushing Wrath lasts 2mins
Crushing Wrath and Exalted with Baron Nasher are of interest in that they are both non-transferable. If it's owner is killed, the buff is lost

Crest of Crushing Wrath: This unit deals % increased damage

Crest of Flowing Water: Increases movement speed by 30%

Crest of Nature's Fury: Increases attack speed by 20% and reduces cooldowns by 10%

Blessing of the Lizard Elder: The unit's physical attacks slow the target's movement speed by (10/20/30)% (at levels 1/6/11) and deal (7.7 + Level * 2.35) true damage. This buff's monster spawns at 2:10 and respawns every 4mins. It lasts 2mins 30s

Crest of the Ancient Golem: This unit regens 1.5% mana (or energy) per second and has (16 + Level * 0.5)% cooldown reduction on their abilities. This buff's monster spawns at 1:55 and respawns every 5mins. It lasts 2mins 30s

Exalted with Baron Nashor: This unit gains 40 ability power, 40 attack damage, 3% of max health regen per 5s, 1% of max mana regen per 5s. This buff's monster spawns at 15:00 and respawns every 7mins. It lasts 4mins

Exalted with Baron Nashor is unique in that the buff is given to every living player on the team, regardless of participation in killing Baron Nashor. It is also the only buff not affected by Utility Mastery


ITEMS

Items are split into 5 categories: Consumable / Basic Tier / Advanced Tier / Legendary Tier and Removed.

Boots of Speed is the only basic item which grants a unique passive

Only 1 pair of boots will increase your movement speed. If 2 pairs are in your inventory, the highest movement speed will be used. Other affects on boots, including unique passives, still take affect

Ninja Tabi is the only item that grants dodge chance

There are 19 primary effects and 3 categories of secondary effects.

Primary effects:
Ability Power, Armor, Armor Penetration, Attack Speed, Cooldown Reduction, Critical Strike, Dodge, Health, Health Regeneration, Life Steal, Magic Penetration, Magic Resistance, Mana, Mana Regeneration, Movement Speed, On-Hit Effects, Spell Vamp and Tenacity.

Secondary effect categories are Active, Aura and Passive.
