Warcaster Feat: Once you have this, you can cast every spell in the game while wielding a Staff, Shield, and Heavy armor.Ruby of the Warmage: if your interested in weapons other than the Staff, this can be a good substitute.However, it is highly recommended thanks to its increadibe defense. Heavy Armor: If you don't mind the penalty, you don't need 15 strength for plate armor.Shield: Thanks to the nature of this, it can be used as a Divine focus for the few paladin spells you have access to.(A Quarterstaff cannot be used as a focus) Staff: This can be used as both an Arcane Focus and melee weapon, meaning you don't have to worry about Material components for anything.However, there are some clever tricks to get around this. Between needing magical focus, weapons, armor, and shields there is a legitimate issue that you might not have enough hands.
