Overview

Fortitude I is a standard passive Abyss Core in Crimson Desert. It fits into shields, gloves, and footwear, allowing players to stack the effect across multiple equipment pieces for more efficient blocking.
Guard stamina management is critical in Crimson Desert's combat system, especially during prolonged encounters with bosses that chain multiple attacks. Reducing the stamina drain from blocking means players can hold their guard longer before needing to dodge or disengage, which opens up more opportunities for counterattacks.

How to Obtain
Purchased from Witch merchants. Can also be found in supply chests near shield-heavy enemy encampments.
Standard Abyss Cores like Fortitude I can be acquired from Witches who serve as merchants at various camps and settlements across the world. Check with any Witch merchant when you visit a new area, as their inventory may include this core.
Usage and Strategy
Socket Fortitude I into any compatible equipment piece (Shields, Gloves, Footwear) to gain its Guard Stamina Cost -3.0% bonus. The effect is always active as long as the core remains socketed and the equipment is worn.
Tips
The older three-piece example adds three listed 3% reductions to 9%. That sum assumes additive stacking, which is not independently tested by the item record; check the actual combined result before treating it as a guaranteed guard-cost total.
This core is particularly valuable for shield builds and any playstyle that relies on timed blocks and parries.
Recorded effect and acquisition
Learn Gear Blueprint: Fortitude, then craft at a Witch with one Abyss Cell, one Azurite and any one listed Defense Reagent (Cockroach, Camel Cricket, Wharf Roach, Jewel Beetle or Snail). The explicit recorded effect is Guard Stamina Cost -3%. Keep this tier's recipe separate from other gears. These records do not independently establish the older generic drop locations, universal vendor stock, numerical fees or multi-piece stacking rules.
