If you want a spell that vould do a lot in a battle with just few steps and just few mana as spells is your strategic weapom that could help tower and may work alone in getting rid of fiends and getting to the work that towers alone could not do it.
Cracklesnap is a spell of choice if you want so magic and action in your battle where you have to got to the fiends with a spell that have a magic effect and could damage not just one fiend but kore than one in just a few steps and with less mana.
Cracklesnap is a spell that could do some fireworks and hence could eliminate a group of fiends and this is with just 20 mana and this is not much for a spell like it when you could do this magic work with just few spells then you could pass the level.
As I have said with the price of tower that could be used with 80 Mana and more you could use some spells that would do a great action in the battlefield and hence you could pass wave after wave and at the end you could reach higher leagues.
