Guidance On Hardcore

Recently I'm trying out HIH and even though the furthest I got was lvl 52 it has been a fun experience for me
However on my first playthrough I missed out many quest and most of the boss altar, which made me follow the same route every time which was kinda boring

Though at the same time I dont really want to risk myself at hard boss altar/ quests that I don't know about (Rymek boss altar etc)

So it would be nice if there is a brief guidance of quest or boss altar that gives good reward like Haloween 2014 quest or the Bovine barn and things I should avoid or be aware of like the Rymek boss altar

Honestly from 70+ I believe I know most things so it would be nice if the guide was from 1-70ish

 

Be extremely careful with "eco caves" (the caves with a T3/4 chest and exit teleporter at the end), some of them are genuinely scary and I've lost 2 hardcore classes to them.

 

Rapid fire mobs / burst fire mobs such as Steam Weirds or Redbeard are killers in disguise, and can easily shred warriors with negative element defenses. Even just 20 in each element can make a HUGE difference, even at endgame.

Edit: Also going for high defense and agility is usually better than high HP, unless you're a mage.
