Strength of Giants is an excellent Combat Magic spell, a Level 3 Enchantment that requires 3 and zero Gems to use. It applies a +4 Strength bonus to friendly troops and Commanders in a very large area, around 25 squares.
Sort of. Earth Might applies the exact same effect to a single square; it's a Level 1 Alteration that requires only 1. These do not stack.
Alternatively, Strength of Gaia applies this, Barkskin, and 10% Regeneration to just the cater; it's a Level 4 Conjuration that requires 31.
Last but not least, Rush of Strength applies this to your entire army; it's a Level 8 Blood Magic spell that requires 3 and 1.
No problem! Just give an 2 mage 1! Or if you're in no rush in the battle, have the 2 cast Summon Earthpower instead; it's a Level 3 Conjuration that provides the necessary pathboost without needing a Gem, along with Reinvigoration.
