Paragon of Fear
Hero of Chelsith Reborn
Hero of Plane of Shadow
Hero of Heart of Fear
The "Strange Black Rock", "Shifting Shard", "Gestation Crystal Shard", and "Heart of Fear" are items to be collected. They are looted from chests that spawn at the end of the following missions:
- Unveiling the Mystery (Chelsith Reborn mission #1 - drops "Strange Black Rock") - Breaking the Seal (Plane of Shadow mission #1 - drops "Shifting Shard") - Menace, Doom, and Horror (Heart of Fear mission #1 - drops "Gestation Crystal Shard") - An End to Fear (Heart of Fear mission #2 - drops "Heart of Fear")
"Paragon of Fear" involves the completion of all Tier 1 and Tier 2 missions, and the three "Hero of..." achievements involve the completion of all Tier 3 and both Tier 4 missions.
Mission writeups along with pre-requisite outlines are documented in this wiki article.
All of the above class weapons are upgradeable to a raid version. To upgrade, loot an Eye of Fear from one of the three Heart of Fear Tier 4 raids and, inside a Rust-Tinged Box of Fear, combine it with your Dreadstone weapon. This combine results in a "Possessed Dreadstone" weapon, the raid version of your class weapon.

Correction:
The Depths of Fear achievement does not include "Paragon of Fear" (which is actually called Paragon of Rain of Fear, by the way).
The requirements are actually:
- Strange Black Rock - Shifting Shard - Gestation Crystal Shard - Heart of Fear - Lesser Hero of Rain of Fear - Hero of Chelsith Reborn - Hero of Plane of Shadow - Hero of Heart of Fear
Below is info on the collect HoF sets. This is based on having completed the entire RoF collection set numerous times across multiple toons and my trusty spreadsheet that I use for notes, tracking, etc.
No Body Left Behind - Ground spawns in Threshhold and are predominately in/around the zone in. Hidden Faces - Ground spawns in Epicenter predominately in the Northwest tunnels and zone out Whuzzle's Worst Nightmare - Ground spawns in Rebirth predominately in the Southwest tunnels and zone out. Kill Them Before They Grow - Dropped by newly formed mobs in any of the three HoF zones.
Due tp the highest concentration of gestation crystals, your best bet for farming the newly formed mobs is in Epicenter in the Northwest tunnel while simultaneously camping the ground spawns for Hidden Faces. Either that or in the middle area.
Not even close to being an Epic. Nothing more than a class specific reward weapon for completing missions. Not to mention they are ever so slightly behind the top group/raid weapon in stats (but equal in damage ratio). Dreadstone has less hp/m/e that top group weapon, and same for Possessed raid version. They do have bonus Heroic on primary class stat, however Tier 1 CoTF weapons just blew them out of the water and have heroic bonus stats out the wazoo. We haven't even really broken in these yet.
