I played my first HC character in D3 - Wizard. I lived to lvl 9. Met up with a Barbarian who I've never met, friended him and we adventured. I was nearly trapped away from my Barbarian buddy 3 times in different battles and certain death seemed the inevitable result in the under levels of the cathedral, but miraculously I lived (super click-click-click micro :D). My then party of 4 (grown to 2 barbs, 2 wizards) went on to defeat the skeleton king. After the glorious battle I missile'd my way into a plaines forest on the next quest. In the forest I killed a curious tree which animated and uprooted to attack. I sent a rolling congo line of magic death spheres at the creature. I totally killed that evil Ent. However, I had stepped in a puddle of its green goo which remained after the tree had died, for a mere 2 seconds, which turned out to be deadly since the green ground puddle was poisonous...
AerJinn I hardly knew ye..
My next HC - Wizard ;D
Now I have a lvl 16 Wizard in Act 2. The party that helped me get through Act 1 was with me. Within the first 5 minutes of Act 2 my party had attracted too many monsters to handle and we got routed all the way back to the city gates - a full 2 minutes of sprinting back to the safety perimeter of town. Two barbarians died trapped by the swarms (rip Joe, Barbie). The DH and I made it back to the city gates with the help of consistent slow time casts. I didn't even really know Joe and Barbie in rl but they helped me get some good Intelligence boosting armor. Joe gave me a legendary ring that added intelligence and more before he was slain >.<
To awesome ppl who nevertheless fall beside you gloriously! I will not forget that unforgiving bloody route which claimed the lives of half of our party.
Edit: Added latest tale of woe while HC'ing
