The Grudge Engraving is one of several available to players in Lost Ark. Grudge Engraving increases the damage players do to bosses and higher-level enemies by +4/+10/+20% while also increasing the damage players receive by 20%.
It's an incredibly risky Engraving to use, and due to the tradeoff, it is only worthwhile at Engraving level 3. That being said, the raw damage output is so massive that many deem it a necessary Engraving for clearing the most difficult content in Lost Ark.

Some other engravings to consider, depending on the player's class, are Cursed Doll, Keen Blunt Weapon, Adrenaline, and Master of Ambush. Engravings are first introduced around level 27 to 30 but won't become a loadout staple until after level 50.
- Cursed Doll - Increases attack power by +3/+8/+16% while decreasing healing by -25%
- Keen Blunt Weapon - Increases crit damage by +10/+25/+50% but imposes a 10% chance that attacks will deal -20% damage
- Adrenaline - Increases attack power by 0.3/0.6/1% for skills that are not mobile or basic attacks for six seconds and stacks up to six times for a potential critical hit rate of 5/10/15%
- Master of Ambush - Increases successful back attack damage by 5/12/25%
