Blade Recommended Engravings

Information mainly from Reitear and what I see on Loaehae/Inven.

Remnant Aura

• The description seems self-explanatory. Since I haven't played Blade myself, I'm going off of Loahae.

• The engraving is popular among all the top Blade players.

• The engraving is purchased for 400k shilling at the main city vendors. (Luxury Merchant)

Super Charge Engraving

• Blade's Charge skills are Soul Absorber and Blitz Rush.

• Remnant Aura and Super Charge don't appear together, and one is usually taken in place of the other.

• The 1st Super Charge Book is obtained from Tier 1 Accessory Maps.

• The 2nd is obtained from Tier 2 Accessory Maps. 

• The 3rd book drops from T7 Igrexion Raid (GR27).

Grudge

• Engraving pictures are self-explanatory. Super Charge and Grudge should be the two main engravings on RU.

• The 1st engraving requires 3 unique books. They come from Goblin Island Max Epona Reputation, Slime Island [Slysburg] Max Epona Reputation, and Island of Sublimity (West Sea).

• The 2nd engraving requires 3 books. They can drop from Island of Serene Sabbath Boss + Reward Box (Low Drop Rate), Blue Hole Island (Auction), and Illusion Island (ultra fucking low drop rate, fuck this island).

• The 3rd engraving comes from T6 Akates Raid (GR23). You need 20 of them.

Backstab

• Back attacks deal 20/30% more damage.

• The 1st engraving requires 20 books. The 1st book is obtained from Tier 1 Calendar Boss spawns.

• The 2nd engraving requires 2 books. The 1st is from maxing out affinity with Sasha (KR). The 2nd is unknown.

Invincible Evasion

• When using your spacebar, you gain invincibility for the duration of the spacebar give or take half a second.

• Drops from Tier 2 Calendar Bosses.
