14.10: another patch thats horrible for hecarim, i actually recommend to stop playing this champ for now until heca or items get a buff but if u still want to play hecarim here u go. ghost nerfed, they removed the tenacity rune so now we have to change our build again. this means we cant buy the cheap ability boost early on, now we have to look for either tenacity or armor boots. 1 good thing is black cleaver got buffed but the negatives are too much.

14.9: big changes, steraks got a big nerf, you almost never buy this item anymore now we go for death dance which got his healing buffed. MAW still a most buy if ap champs. Eclipse got nerfed for 2%dmg but theres no other better options. sundered sky also got a big nerf.

14.8: nothing changed but bad news are coming, next patch 14.9, hecarim core items eclipse, shojin and sundered sky are possibly getting nerfed which would kill the heca in an instant.

14.7: nothing changed.

14.6: nothing changed.

14.5: Changed main build. black cleaver is now almost always build 3rd. Opportunity still good for snowballing or squishy champions.

14.4: black cleaver did get buffed, good to buy if 2+ tanks otherwise build stays the same. Stridebreaker also got buffed but its still useless item.
I added a new build that i like for Conqueror users, its a tanky build with a lot of sustain, very good against melee champions.

im a high elo jungler OTP hecarim peaking challenger. my opgg if you wanna see builds on specific matchups. https://www.op.gg/summoners/euw/chaaz47%20ttv-1337

i also post my ranked games on here https://www.youtube.com/channel/UCsnV20qVhw1zSrHSlHf6uhw and stream on twitch.tv/chaaz47

i recommend watching my youtube replays to improve further.

I had a lot of problems with getting invaded and lost many games. Since your so weak early and you lose most 1v1s against conquerer/lethal tempo junglers, the higher the elo the higher the chance you get invaded. Your first clear is the most vulnerable especially against kindred, nidalee and rengar. its better to drop the camp and not contest them. counterjungling or ganking.

Most Hecarim players dont optimize or forget the Q stacks.
Its always a good time to fight if you have the maxed Q stacks.

Hecarim is a full clear jungler, farm and get ahead of cs. Look if theres enemy laners that are low hp and gank them otherwise dont bother and keep farming. If your laners are pushing hard make sure to look for counterganks since theres a high chance enemy jungler will gank them.

You can look for early Lv3 ganks if for example you have a laner that gets bullied a lot example talon vs kassadin. even if you dont kill talon its good to gank once midlane to damage talon a bit so kassadin can survive the lane. another example to gank lv3 is toplane ranged matchup like vayne or darius, you can also Lv3 gank them as they always push and play agressively, it will help out your laners immensely. and one more thing lv3 ganks only with red buff for the slow.

95% of your games path botlane. you can path top if you think that in botlane nothing will happen, example 2 enchanter supps, lulu vs janna.

Also most people forgot this rune.
It gives you attack damage and movement speed in rivers.
Fighting in rivers is preferable

Hecarim is a good champ to do voidgrubs but only if you have prio on lanes or know that enemy jungler is on the opposite side. If enemy jungler is doing voidgrups and you have 0 prio on lanes go for drake. Buy control wards. Make sure your botlane is safe they like to die a lot. Avoid rift herald it takes to long and not that useful.
You can use your ults defensively to fear people that engage on your botlane/teammates or use it as a engage but theres a risk of missing and dying.

This is my first ever guide.
Im open to suggestions and can put new stuff if you have questions.
Thanks for checking my guide!
