Pay attention to your party’s resistances

Speaking of elemental coverage, don’t make the mistake of only focusing on your offenses without paying attention to your defenses. Shin Megami Tensei V uses the series’ signature “Press Turn” battle system, which rewards your party with extra turns whenever you hit an enemy’s weakness or score a critical hit. However, this also applies to the enemy party. Even if your demon can shrug off taking the extra damage of an attack it’s weak to, it’ll put your entire party at risk of a wipe if an enemy party exploits that weakness to hit you up to six more times in a single turn.
For this reason, you often don’t want to assign specific niches to each party member that no one else can fill. Instead, spread your support skills and elemental attacks across demons with varying weaknesses to avoid the risk of letting an enemy pin you. Additionally, passive skills like Resist Fire can cover up a demon’s weakness and make it viable in more encounters. If a boss monster is giving you trouble, focus on building demons that best resist its attacks.
