Summons: Your thoughts.....

[HoneyBadger]

I'll go along with Sombre, but if it weren't for the max unit limitation, I'd suggest having more summons come with leaders, or secondary units atleast, just for the sake of interest.

For the fire gems, use them in battlefield spells, and spam living fire. Also, boost your fire mages with them using empowerment. The only elemental in-battle summon I'm not a fan of is earth, or air against large opponents. Fire is pretty powerful, as is water.
