I'm thinking shock or fire.
I already have an Electron Charge that I could upgrade to 4 star, but its range seems kinda small on the Wiki, and Tier 3 Wolvers can supposedly dig out of the vortex. I don't plan on making any status bomb higher than 4 stars because I'm penny-pinching my only 1000 CE left for a new helmet.
Please provide some suggestions for me to use. I could really appreciate them since I unlocked Tier 3 a while ago but only decided to try out its first half today!
This should probably be move to arsenal.
As for the best...I guess that's a matter of opinion.
I like the freezing series, since it can slow down hoards and have my guild mates set up for some charge attacks. But the Shock and fire series are really good too, but I feel something that can slow a hoard down is much better than just inflicting some damage here and there.
Although, I would really consider upgrading them to 5* in the future, that extra range does help a lot.(Obviously it doesn't have to be now, but its recommended that you do it asap.)
