Mid Game is where Calico starts to get active
Your biggest powerspike is T3 ult, after which you are able to win most fights 1v1
Maintain high soul value by constantly using to run boxes, invading their jungle and clearing camps
Your goal is to pressure the enemy team as much as you can
Try to always take trades with the enemy to pressure them, giving your team more space
Souls are REALLY important on Calico, so find a balance between farming and fighting.Usually being around 4 k souls above most of the enemy players is more than enough to do devastating damage
Remember to get mid boxes at 10 minutes and every time they respawn
Also decide if you want to upgrade Bombs T3 first or Cat Form T3 first if you think you want to heal more without going to base.
