D&D 5E Storm Sphere (5E) value?

[Donkey Kong]

this spell is good but remember you prolly wont get more then one lightning zap out of it. it lasts for 1 min which is 10 rounds now lets say you have 5 ppl with you and your fighting just 5 enemies. you spell will end by the time it gets back to your turn. and now lets say you have 6 ppl in your grp and are fighting 8 orcs your spell will end in theory before the orcs get threw their turns.

Donkey Kong, keep in mind that everyone gets a turn during a single round. With this in mind, there is 10 rounds, so the spell will likely be up for the entire combat.
