__**Rune Explanation**__
Conq + Triump + Alacrity + Last Stand are all standard bruiser runes. Difference between Coup and Last stand is minimal, but if you are playing assassin build go Coup > Last Stand.

Boots is 300 free gold + 10 extra movespeed, helping you get better E + Q combos on backline enemies. Cosmic Insight is necessary on Jarvan because our flash is extremely valuable for ganks and fights.

__**Standard Core Build**__
Eclipse | Ionian Boots | Sundered Sky | Black Cleaver | Spirit Visage | Frozen Heart


__**Core Explanation**__
You want to prioritize Ability Haste on Jarvan when deciding your items. If your entire team has enough damage, you can skip Black Cleaver 3rd and go for full tank
Don't take potion of Jarvan, you are not looking to spam gank, you are looking to get to level 6 and then farm immobile carries.

**Eclipse ** - One of the strongest solo queue items on bruisers, and Jarvan utilizes it very well.
**Ionian Boots** - Always take Ionian early game on Jarvan unless they have clear heavy CC or full AD. Later on in the game you can switch Ionian for Plated or Mercs
**Sundered Sky** - Crucial item on Jarvan as it enhances your passive when you get your first auto + is really good with Spirit Visage 3rd/4th item. This combo with Eclipse is OP
**Black Cleaver** - Normally you could go defensive 3rd/4th item but in lower elos you want to snowball / deal DMG to carries so you can fight. This item gives good haste, hp, dmg, + armor shred, so it's a perfect item on Jarvan.
**Spirit Visage** - Broken item with Sundered + Eclipse - it enhances your shielding and HP gained. Very good item with enchanters as well.
**Frozen Heart** - Best armor item because it provides haste + good armor. Most other armor items don't give haste, and on Jarvan haste is crucial.

__**Boots**__
**Ionian** - Go to boots on Jarvan always.
**Steelcaps** - Good VS heavy AD + auto attacking comps.
**Mercs** - Necessary VS heavy CC comps (ex: Leona, Amumu, Zyra)

__**Armor Items**__
**Randuin's Omen** - If enemy has 2 crit champs always go Randiuns (yone, yasuo, any ADC, graves/kindred/viego).
**Death's Dance** - If enemy has very high burst and you are looking for more DMG in the fights. Also very powerful if you know you can secure a kill in the fights, so if you have an assassin you can combo with while utilzing this item it can gain even more value. AD version of Maw.

__**MR Items**__
**Abyssal** - If your team has 2+ AP carries and enemy has decent magic damage, this item will enhance your carries + help you deal with enemies. Also provides solid haste.
**Force of Nature** - Best MR item if the enemies have CC or multiple forms of proc'ing stacks. (Liandries, Blackfire, etc). Also good for MS if you need to connect your Q's on mobile champs.
**Maw** - If enemy has high burst and you are looking for more DMG in fights. Very solid if you are dealing with Veigar, Karthus, Elise, etc. AP version of Death's Dance

__**Snowball Items**__
**Serpents** - A must buy item if enemy has shielding
**Axiom Arc** - If you are extremely ahead in terms of kills/gold for yourself, and you can guarantee kills on their backline, very OP item.
**Steraks** - Very situational item if enemy has high CC + burst. The shield + tenacity and extra DMG you get can be useful in some situations.


__**Assassin Build**__
Opportunity | Ionian | Profane Hydra | Seryldas | Edge of Night | Axiom Arc

__**Assassin Build Explanation**__
Strong build if your team lacks damage or if the enemies are 4-5 squishy, and you are able to consistently kill the enemy backline. NOTE - if your team has a solid comp, this build will not be good

**Opportunity** - Strongest first item on most lethality junglers. Jarvan uses the extra lethality from the item to burst enemies and after one shotting the movespeed you get is very to escape when you don't have any cooldowns left
**Ionian** - Strongest boots on Jarvan, it's a must go for the assassin build since most lethality items do not provide any haste.
**Profane Hydra** - Solid item that gives good burst DMG + clear + haste.
**Serylda's Grudge** - Solid item that start's getting more value as other champs level up and gain more base armor. Also provides haste which Jarvan loves!
**Edge of Night** - Really helpful during the initial engages, and provides the extra HP that no other lethality item offers.
**Axiom Arc** - Strong item if you can consistently get kills / picks. Helps optimize using your ultimate. Can also take this item earlier if you are snowballing harder. Can finish 4th/5th item with really any lethality item that fits in the situation.

__**Situational**__
**Serpents** - A must buy item if enemy has any shielding. Can take this item after or before Opportunity.
**Umbral** - Really powerful versus enchanter supps and immobile mages on the side lane. Also really OP if you have a hard engage supp on your team. Item is super cheap, so you can dominate the map if you are snowballing hard.
**Yomuu's** - Rarely take this item on Jarvan, but if you absolutely need the movespeed to make it onto enemies during fights, it can be useful.
