Mass Effect 5e - Player's Handbook

To qualify for a new class, you must meet the ability score prerequisites for both your current class and your new one, as shown in the Multiclassing Prerequisites table. For example, a vanguard who decides to multiclass into the infiltrator class must have both Dexterity and Intelligence scores of 13 or higher. Without the full training that a beginning character receives, you must be a quick study in your new class, having a natural aptitude that is reflected by higher-than-average ability scores.

Multiclassing Prerequisites

When you gain your first level in a class other than your initial class, you gain only some of new class's starting proficiencies, as shown in the Multiclassing Proficiencies table.

Multiclassing Proficiencies

Your capacity for biotics depends partly on your combined levels in all your biotic classes and partly on your individual levels in those classes.

Spell Slots & Cantrips. You determine your available spell slots and cantrips by adding together all your levels in the adept class and half your levels (rounded down) in the sentinel and vanguard classes. Use this total to determine your spell slots and cantrips by consulting the Multiclass Biotic Table.
