Alacrity cold snap forge spirits in any order. Tornado cold snap meatball. Tornado cold snap ice wall. Cold snap ice wall alacrity. Tornado emp ice wall. You get the idea, any useful combo you might do with 3 spells, just go for it in training mode. In fights, you just wait and invoke spells anyways so you'll either cast constantly as soon as you can, 2 spell combos, or you're waiting all the way and getting another 3 spell combo off. So 3 spells quickly is generally the most important thing to be able to reach next level invoker. Ofc late game you can just send spell after spell after spell, but usually it's in 3 spell combos even then
