Phase Rush makes it so you can catch up to enemies quicker and everything in the sorcery tree pretty much, you can either catch up to enemies faster or you can run away from them faster. This also means, if you’re in a good matchup you can snowball it harder and if you’re in a bad matchup you can escape it easier.

Now, things get a bit trickier when we dive into item choices. Hecarim’s got a few different builds that you can do depending on the enemy team composition.

You always want to rush Ionian Boots of Lucidity every game, then you want to get your Tear of the Goddess on your first back. After this you want to get Duskblade of Draktharr if the enemy team is mainly squishy champions (4 or more champions on their team don’t build armor) if the enemy team is mainly tankier you want to go Eclipse.

The first option for build is the Assassin Build. You are gonna go this build path when the enemy team has little to no lockdown champions.
The second option is the Anti Lockdown Build if you are facing a team that's all about keeping you locked down. (For example: Maokai jungle, Sylas mid, Nautilus support)

Let’s go over the main thing that made Dantes Challenger in Korea, whereas most Hecarim one tricks have trouble making it out of diamond in EUW or NA nowadays. Pathing is the biggest key thing for Hecarim, it’s the reason Dantes is able to out-jungle LCK pros every game and why he’s able to take a champion like Hecarim and make him unpredictable and just 1v9 games.

There are 5 potential pathing options that you can choose every game. Dantes recommends to full clear for lower elo players, because: you can’t trust your teammates and as a result you don’t want to take any pathing options that would put reliance on your team and it’s also the most consistent way to get a lead. But, once you start getting into higher elos (Emerald, Diamond+) you can start exploring the other options.

Option A: Full clear top to bot. This is Dantes’ go-to 90% of the time. It allows him to reach bot lane at level 4 and potentially initiate a bot lane gank. If no gank opportunities arise, this pathing puts him on the same side of the map as Dragon. If the enemy jungler chooses Option B, you can secure a free dragon after your second full clear.
Option B: Three-camp clear of your red side with a raptor start. Ideal for early impact, especially with a support offering strong CC like Thresh or Nautilus.
