Marauder Veng/Reck/Repost/TANK

Hello,
Im pretty new to PoE and im trying to get a build together that i thought would be fun to play around with.
Trying to create a tank thats pretty much using Vengeance/Reckoning/Reposte has its main damage while trying to get to 100% chance block. But im having a hard time trying to figure out what items ill need or should be trying to get for something like this.
Side note because me and my friend are hardcore masochist we decided to start playing the game only on HC.

Currently im level 39
Always in a party of Two
Main Abilities:
Heavy Strike+Melee Physical Damage+Melee Splash
Vengeance+Melee Physical Damage
Reckoning+Melee Physical Damage
Reposte
Abyssal Cry

Not sure how to link what gear i already have can if someone can help me there?

At the left of the Path of Exile logo you should see an image of one of your characters. Click that and it will bring up a window where you can click on items to link them from your inventory, as well as from stash tabs.

Vengeance/Reckoning/Reposte are used to augment your overall damage. They will not work well as a primary damage source because they have hard-cooldowns and are reactionary in nature. If you really wanted to go that route though, you'll find Punishment to be a good curse to go with that play style. That being said, I still wouldn't recommend it, especially for HC. Standing around waiting for things to hit you will start to get boring pretty fast (and if you're fighting a boss, they'll hit you harder than you hit back). You should still use Vengeance/Reckoning/Reposte, but don't depend too much on them.

I also noticed you use Heavy Strike with Melee Splash. I think you'll find that Ice Crash is not only more enjoyable, but will also work better overall, mainly because you won't need Melee Splash and can replace it with gem that adds more DPS (faster attacks or added fire damage).

One last thing: block cannot go over 75%. Reaching 75% chance will still be very, very hard though regardless.

block caps at 78% with this

Thanks for the help so far ill try out that other ability and see how that goes, so far i dont have to wait to long usually the abilities are constantly going off damaging everything around me was hoping i could some how manage a 100% block guess not which is fine i can change out and try for something else still havent done a full respec yet but ill see where this keeps going, or play it out till it dies.
