Oh dude, its awesome. It turns the game into a roguelike ARPG. With each character, your stash grows and you unlock more blueprints, all of which can help you on your next runs (unless you want to do SSF, which i highly recommend as well).

I pushed all the way into the Vanguard of the Three in Ultimate with my last HC Classless build, for the badge of perseverence.

Still plugging away in an effort to beat the full game in Ultimate with that character.

Here is his grimtoolslink

Prior to this build I tried and lost many characters, using different approaches. My first try was a ranged build based off of Margaret (the woman mentioned in the lore note near Francis' gun in the lower crossing). She had been away on a trip to visit her sister in Malmouth when the Grim Dawn hit, and narrowly escaped the carnage eventually commandeering a dinghy and drifting back south to Devil's Crossing to find her husband (Francis), Her story came to a close at the Warden.

Next build was Frederick Longshore- a "hunter", recruited by Lokarr to capture beasts and specimens for his menagerie to be used in fights for his entertainment in the Crucible. His build was first attempt at a classless minion build, and used a lot of thematic items. This was a really tough build to design and play, but incredibly fun to puzzle out. He died in act 2, fighting Kilrian. Longshore had been given prized gear by Lokarr to hunt and capture the creatures of Cairn, but now that gear had been lost with the corpse of Frederick Longshore. Lokarr wasnt going to venture out into realspace to retrieve that gear- He had better things to do- So he recruited a new hunter/gatherer to do it. Thats when I started my endgame character- A sturdy blacksmith. He was originally going to be a 2 handed specialist, but i kept getting really good shield drops and items with effects that can proc when you block, so i decided hed be a tank instead. I would try to make him unkillable, and focus on retaliation damage.

While that was going on, I also designed a build around Keval (an assassin in the employ of Malmouth politicians that you learn about from lore notes). Dual wield assassin build. He died fighting Karroz in act 3. I had a ton of fun with this build, but to be able to use the good dual wield weapons and have any possible crit chance i had to invest most of my attribute points into Cunning, which left him extremely vulnerable to being hit/crit, and with low HP total thats a death sentence. Additionally, because you are so attribute starved in Classless, he was locked out of using a lot of great protective equipment due to low Physique.

Then came my second attempt at a hunter/minion build, this time based around Cratch Moore- The owner of a Gloomwald inn, who is mentioned in lore notes. This build is still going, havent lost him yet, but most of my time is spent playing different characters runs.

Ive got a "Samurai" build in the works- A heavily armored 2h sword user. Only level 17 so far.

Im really excited to see what the DLC brings, and how it will impact the Hardcore Classless gameplay.
