The catalan spell isnt worth the trouble storm already got a single-hit rank5 spell, stormzilla.
changes that can be done is:
decrease the damage and make it AoE, that way storm doesnt always have to use lord or tempest as lower rank AoE
decrase damage and add a stun effect (1-2 rounds)
make it remove shield before attacking
make it cleance charm before attacking
make it destroy 1 power pip on opponent
Having another rank5 spell with no special effect just make it pointless, Thank you for your time and i hope you change it.
Catalan is more reliable then Stormzilla. I'd craft it if I could, but I am not the right rank, and I don't foresee myself beating the Zafaria crafting quest right now.
