Steadfast block in "Episode INTERmission".
In "Episode INTERmission", the player can pick a steadfast block materia from a materia pod in B15 Production Facility of Shinra Building's Advanced Weaponry during "Find That Materia" in Chapter 2, "Covert Ops". Followed by an attack from Shock Troopers, at the end of the room, the player can operate the computer terminal to reactivate the power and open some of the pods.

Use[]
Cloud guarding.
Steadfast block materia improves guarding, causing it to further reduce damage to up to 65%, at the same time building the user's ATB gauge. Against enemies who resist physical damage, the materia can allow characters to build their ATB gauge without attacking. Because characters guard often while not controlled by the player, it can be an effective way to increase the rate their ATB fills when not in the player's control, while also taking less damage.
Steadfast block materia is best on Cloud whose slow movement speed and being a melee character mean he will be guarding more often than most characters, and thus, will benefit from the improved damage mitigation. There are also storyline bosses in the late game Cloud has to face/start alone, where guarding is beneficial. Barret will similarly be guarding often, due to his slower move speed, though he is normally ranged and will guard less often than Cloud. He can further improve his durability with Steelskin. Though Tifa is a melee character, she relies more on her mobility and being able to dodge attacks.
Steadfast block works well alongside 
Parry Materia to further increase the ATB gauge by parrying as well as by blocking attacks. With 
Barrier the characters can take even less damage. On characters the player is not controlling much, it can be coupled with Crescent Moon Charm.
In "Episode INTERmission", steadfast block is more useful in Sonon who is not directly controlled. The AI has him guard often, and he often struggles to build ATB. Yuffie, meanwhile, is more of a ranged fighter, can precision-guard to negate damage, and has Brumal Form to avoid attacks altogether.
