As your character becomes stronger, you are yet to face more challenges and during The Season of Blood, certain accomplishments will grant you well-earned rewards.
The fifth chapter of the Season Journey provides you with rewards after you have strengthened your character, which means more Nightmare Dungeons and Blood Harvest farming.
This chapter of the Season Journey will help you prepare for World Tier 4, which is where things begin to get more intense as you are now in the endgame.
Season 2 Season Journey Chapter Slayer Objectives
1) Reaching For Greatness
Improve a Paragon Glyph to Rank 21 after finishing Nightmare Dungeons. (The higher the level of the Nightmare Dungeon, the faster your Glyph can be leveled up)

Defeat Grigoire in Nightmare, which can be done by summoning him at the Dry Steppes after you have obtained Living Steel from Helltides.

Equip a Sacred Legendary item in every slot. (Legendary items are not hard to come by once you reach World Tier 3 and 4)

Season 2 Chapter Slayer Rewards
With a total of 12 objectives in the Slayer Chapter, you will need to complete at least 10 of them to obtain the chapter rewards.
1) Epic Favor
A huge boost in favor of providing you with even more progress so that you can claim rewards from your Battle Pass.
2) Salmagundi
Another mount that you can obtain and equip later at the Stablemaster. (It seems that the Mounts that are rewarded are still bugged and don’t appear for some players)
3) Firth Journey Cache
Another Cache that contains many of the valuable late game resources along with Pact Armor, Potent Blood, and a Scroll of Amnesia.
The Scroll of Amnesia is an item that allows you to refund all your allocated Skill Points and Paragon Points.
4) Aspect of Elements
The Aspect of Elements provides any class with an increased amount of damage to certain damage types for 7 seconds.
This changes and will swap between Fire, Lightning, and Physical or Cold, Poison, and Shadow, allowing you to use it for certain builds.
Verdict
Slayer is the first step into the real end game and is meant to give you a push towards Level 70 but you will need to grind a bit to complete some of the objectives.
Focusing on each of the objectives that are related to each other would be the best way to progress, such as farming in Blood Harvests or sticking with Nightmare Dungeons.
Completing the objectives in the Slayer Chapter is easier if you are around 65 to 70 as it is mostly expected that once you complete it, you will be ready for World Tier 4.
