every general gets a type of minion from their skill tree.
Oak-Spirits
QoT - Bramble things
Lord Eb. - Armored bouncing balls (no idea name, I don't play him)
Selena - Yeti's
The totems are extra minions you can summon if you wish. you can controll all your minions as if they were you. N by default selects you and minions and M selects just minions.
Hope it helps
