So basically, they’re some sort of guardian thing?
Hmmm… Considering how traditionally bad at taking hits magic users tend to be… That would probably be useful. Also, brace yourself, I have a feeling those things need particualrly powerful spells, like a Tsunami
A large wave rises up behind Tardises and flows towards the machines, passing right by anyone who Tardises was not targeting leaving them unharmed. The wave does not simply pass right by the machines, though. They are caught up in it.
(OOC: Tsunami is multi-target by default. Bubble and Whirlpool were not. The main reason for the sword is so he can use it to work around split damage, really.)
