The Blazebreak, Blizzbreaker, and Surge Breaker shields are all 3star shields that are fairly pointless. So my idea is to give them a special shield bash which inflicts their related statuses, fire, freeze, and shock respectively. This would be similar to the swiftstrike buckler which is a 3star but is also useful in endgame in some circumstances.
Of course I'm no expert at balancing, so maybe in addition the shields could deal mixed stun and their related status, so the shield bash for the blazebreak shield would deal fire AND stun at the same time.
Also, due to frozen and shocked enemies potentially getting in the way of the bash and defeating the purpose, the shields would deal the statuses by leaving a trail of mist that would inflict the status to enemies behind it, and not in front.
Discuss!
Leaving a trail of mist behind would do absolutely nothing, as your shield bash would push enemies away. Nothing should be behind you when you shield bash.
